    updated job prevents it's recovery when slurmctld restarts.
 -- Add support for cluster-wide consumable resources. See "Licenses"
    parameter in slurm.conf man page and "--licenses" option in salloc, 
    sbatch and srun man pages.
 -- Major changes in select/cons_res to support FastSchedule=2 with more
    resources configured than actually exist (useful for testing purposes).
 -- Modify srun --test-only response to include expected initiation time 
    for a job as well as the nodes to be allocated and processor count
    (for use by Moab).
 -- Correct sched/backfill to properly honor job dependencies.
 -- Correct select/cons_res logic to allocate CPUs properly if there is
    more than one thread per core (previously failed to allocate all cores).
 -- Correct select/linear logic in shared job count (was off by 1).
 -- Add support for job preeption based upon partition priority (in sched/gang,
    preempt.patch from Chris Holmes, HP).
 -- Added much better logic for mysql accounting.  
 -- Finished all basic functionality for sacctmgr.
 -- Added load file logic to sacctmgr for setting up a cluster in one step.
 -- NOTE: We needed to change an RPC from version 1.3.0. You must upgrade 
    all nodes in a cluster from v1.3.0 to v1.3.1 at the same time.
 -- NOTE: Work is currently underway to improve placement of jobs for gang
    scheduling and preemption.
 -- NOTE: Work is underway to provide additional tools for reporting 
    accounting information.

* Changes in SLURM 1.3.0
========================
 -- In sched/wiki2, add processor count to JOBWILLRUN response.
 -- Add event trigger for node entering DRAINED state.
 -- Build properly without OpenSSL installed (OpenSSL is recommended, but not 
    required).
 -- Added slurmdbd, and modified accounting_storage plugin to talk to it. 
    Allowing multiple slurm systems to securly store and gather information
    not only about jobs, but the system also. See accounting web page for more
    information.    

* Changes in SLURM 1.3.0-pre11
==============================
 -- Restructure the sbcast RPC to take advantage of larger buffers available
    in Slurm v1.3 RPCs.
 -- Fix several memory leaks.
 -- In scontrol, show job's Requeue value, permit change of Requeue and Comment
    values.
 -- In slurmctld job record, add QOS (quality of service) value for accounting
    purposes with Maui and Moab.
 -- Log to a job's stderr when it is being cancelled explicitly or upon reaching
    it's time limit.
 -- Only permit a job's account to be changed while that job is PENDING.
 -- Fix race condition in job suspend/resume (slurmd.sus_res.patch from HP).

* Changes in SLURM 1.3.0-pre10
==============================
 -- Add support for node-specific "arch" (architecture) and "os" (operating 
    system) fields. These fields are set based upon values reported by the
    slurmd daemon on each compute node using SLURM_ARCH and SLURM_OS environment 
    variables (if set, the uname function otherwise) and are intended to support
    changes in real time changes in operating system. These values are reported
    by "scontrol show node" plus the sched/wiki and sched/wiki2 plugins for Maui
    and Moab respectively.
 -- In sched/wiki and sched/wiki2: add HostFormat and HidePartitionJobs to 
    "scontrol show config" SCHEDULER_CONF output.
 -- In sched/wiki2: accept hostname expression as input for GETNODES command.
 -- Add JobRequeue configuration parameter and --requeue option to the sbatch
    command.
 -- Add HealthCheckInterval and HealthCheckProgram configuration parameters.
 -- Add SlurmDbdAddr, SlurmDbdAuthInfo and SlurmDbdPort configuration parameters.
 -- Modify select/linear to achieve better load leveling with gang scheduler.
 -- Develop the sched/gang plugin to support select/linear and
    select/cons_res. If sched/gang is enabled and Shared=FORCE is configured
    for a partition, this plugin will gang-schedule or "timeslice" jobs that
    share common resources within the partition. Note that resources that are
    shared across partitions are not gang-scheduled.
 -- Add EpilogMsgTime configuration parameter. See "man slurm.conf" for details.
 -- Increase default MaxJobCount configuration parameter from 2000 to 5000. 
 -- Move all database common files from src/common to new lib in src/database.
 -- Move sacct to src/accounting added sacctmgr for scontrol like operations 
    to accounting infrastructure.
 -- Basic functions of sacctmgr in place to make for administration of 
    accounting.
 -- Moved clusteracct_storage plugin to accounting_storage plugin,
    jobacct_storage is still it's own plugin for now.
 -- Added template for slurm php extention.
 -- Add infrastructure to support allocation of cluster-wide licenses to jobs.
    Full support will be added some time after version 1.3.0 is released.
 -- In sched/wiki2 with select/bluegene, add support for WILLRUN command
    to accept multiple jobs with start time specifications.

* Changes in SLURM 1.3.0-pre9
=============================
 -- Add spank support to sbatch. Note that spank_local_user() will be called 
    with step_layout=NULL and gid=SLURM_BATCH_SCRIPT and spank_fini() will 
    be called immediately afterwards.
 -- Made configure use mysql_config to find location of mysql database install
    Removed bluegene specific information from the general database tables.
 -- Re-write sched/backfill to utilize new will-run logic in the select 
    plugins. It now supports select/cons_res and all job options (required
    nodes, excluded nodes, contiguous, etc.).
 -- Modify scheduling logic to better support overlapping partitions.
 -- Add --task-mem option and remove --job-mem option from srun, salloc, and 
    sbatch commands. Enforce step memory limit, if specified and there is
    no job memory limit specified (--mem). Also see DefMemPerTask and
    MaxMemPerTask in "man slurm.conf". Enforcement is dependent upon job
    accounting being enabled with non-zero value for JoabAcctGatherFrequency.
 -- Change default node tmp_disk size to zero (for diskless nodes).

* Changes in SLURM 1.3.0-pre8
=============================
 -- Modify how strings are packed in the RPCs, Maximum string size 
    increased from 64KB (16-bit size field) to 4GB (32-bit size field).
 -- Fix bug that prevented time value of "INFINITE" from being processed.
 -- Added new srun/sbatch option "--open-mode" to control how output/error 
    files are opened ("t" for truncate, "a" for append).
 -- Added checkpoint/xlch plugin for use with XLCH (Hongjia Cao, NUDT).
 -- Added srun option --checkpoint-path for use with XLCH (Hongjia Cao, NUDT).
 -- Added new srun/salloc/sbatch option "--acctg-freq" for user control over 
    accounting data collection polling interval.
 -- In sched/wiki2 add support for hostlist expression use in GETNODES command
    with HostFormat=2 in the wiki.conf file.
 -- Added new scontrol option "setdebug" that can change the slurmctld daemons
    debug level at any time (Hongjia Cao, NUDT).
 -- Track total total suspend time for jobs and steps for accounting purposes.
 -- Add version information to partition state file.
 -- Added 'will-run' functionality to all of the select plugins (bluegene,
    linear, and cons_res) to return node list and time job can start based 
    on other jobs running.
 -- Major restructuring of node selection logic. select/linear now supports
    partition max_share parameter and tries to match like size jobs on the 
    same nodes to improve gang scheduling performance. Also supports treating 
    memory as consumable resource for job preemption and  gang scheduling if 
    SelectTypeParameter=CR_Memory in slurm.conf.
 -- BLUEGENE: Reorganized bluegene plugin for maintainability sake.
 -- Major restructuring of data structures in select/cons_res.
 -- Support job, node and partition names of arbitrary size.
 -- Fix bug that caused slurmd to hang when using select/linear with
    task/affinity.

* Changes in SLURM 1.3.0-pre7
=============================
 -- Fix a bug in the processing of srun's --exclusive option for a job step.

* Changes in SLURM 1.3.0-pre6
=============================
 -- Add support for configurable number of jobs to share resources using the 
    partition Shared parameter in slurm.conf (e.g. "Shared=FORCE:3" for two 
    jobs to share the resources). From Chris Holmes, HP.
 -- Made salloc use api instead of local code for message handling.

* Changes in SLURM 1.3.0-pre5
=============================
 -- Add select_g_reconfigure() function to node changes in slurmctld configuration
    that can impact node scheduling.
 -- scontrol to set/get partition's MaxTime and job's Timelimit in minutes plus
    new formats: min:sec, hr:min:sec, days-hr:min:sec, days-hr, etc.
 -- scontrol "notify" command added to send message to stdout of srun for 
    specified job id.
 -- For BlueGene, make alpha part of node location specification be case insensitive.
 -- Report scheduler-plugin specific configuration information with the 
    "scontrol show configuration" command on the SCHEDULER_CONF line. This
    information is not found in the "slurm.conf" file, but a scheduler plugin 
    specific configuration (e.g. "wiki.conf").
 -- sview partition information reported now includes partition priority.
 -- Expand job dependency specification to support concurrent execution, 
    testing of job exit status and multiple job IDs.

* Changes in SLURM 1.3.0-pre4
=============================
 -- Job step launch in srun is now done from the slurm api's all further
    modifications to job launch should be done there.
 -- Add new partition configuration parameter Priority. Add job count to 
    Shared parameter.
 -- Add new configuration parameters DefMemPerTask, MaxMemPerTask, and 
    SchedulerTimeSlice.
 -- In sched/wiki2, return REJMESSAGE with details on why a job was 
    requeued (e.g. what node failed).

* Changes in SLURM 1.3.0-pre3
=============================
 -- Remove slaunch command
 -- Added srun option "--checkpoint=time" for job step to automatically be 
    checkpointed on a period basis.
 -- Change behavior of "scancel -s KILL <jobid>" to send SIGKILL to all job
    steps rather than cancelling the job. This now matches the behavior of
    all other signals. "scancel <jobid>" still cancels the job and all steps.
 -- Add support for new job step options --exclusive and --immediate. Permit
    job steps to be queued when resources are not available within an existing 
    job allocation to dedicate the resources to the job step. Useful for
    executing simultaneous job steps. Provides resource management both at 
    the level of jobs and job steps.
 -- Add support for feature count in job constraints, for example
    srun --nodes=16 --constraint=graphics*4 ...
    Based upon work by Kumar Krishna (HP, India).
 -- Add multi-core options to salloc and sbatch commands (sbatch.patch and
    cleanup.patch from Chris Holmes, HP).
 -- In select/cons_res properly release resources allocated to job being 
    suspended (rmbreak.patch, from Chris Holmes, HP).
 -- Removed database and jobacct plugin replaced with jobacct_storage 
    and jobacct_gather for easier hooks for further expansion of the
    jobacct plugin.

* Changes in SLURM 1.3.0-pre2
=============================
 -- Added new srun option --pty to start job with pseudo terminal attached 
    to task 0 (all other tasks have I/O discarded)
 -- Disable user specifying jobid when sched/wiki2 configured (needed for 
    Moab releases until early 2007).
 -- Report command, args and working directory for batch jobs with 
    "scontrol show job".

* Changes in SLURM 1.3.0-pre1
=============================
 -- !!! SRUN CHANGES !!!
    The srun options -A/--allocate, -b/--batch, and -a/--attach have been
    removed!  That functionality is now available in the separate commands
    salloc, sbatch, and sattach, respectively.
 -- Add new node state FAILING plus trigger for when node enters that state.
 -- Add new configuration paramter "PrivateData". This can be used to 
    prevent a user from seeing jobs or job steps belonging to other users.
 -- Added configuration parameters for node power save mode: ResumeProgram
    ResumeRate, SuspendExcNodes, SuspendExcParts, SuspendProgram and 
    SuspendRate.
 -- Slurmctld maintains the IP address (rather than hostname) for srun 
    communications. This fixes some possible network routing issues.
 -- Added global database plugin.  Job accounting and Job completion are the 
    first to use it.  Follow documentation to add more to the plugin.
 -- Removed no-longer-needed jobacct/common/common_slurmctld.c since that is
    replaced by the database plugin.
 -- Added new configuration parameter: CryptoType.
    Moved existing digital signature logic into new plugin: crypto/openssl.
    Added new support for crypto/munge (available with GPL license).

* Changes in SLURM 1.2.36
=========================
 -- For spank_get_item(S_JOB_ARGV) for batch job with script input via STDIN,
    set argc value to 1 (rather than 2, argv[0] still set to path of generated
    script).
 -- sacct will now display more properly allocations made with salloc with only 
    one step.

* Changes in SLURM 1.2.35
=========================
 -- Permit SPANK plugins to dynamically register options at runtime base upon
    configuration or other runtime checks.
 -- Add "include" keywork to SPANK plugstack.conf file to optionally include
    other configuration files or directories of configuration files.
 -- Srun to wait indefinitely for resource allocation to be made. Used to
    abort after two minutes.

* Changes in SLURM 1.2.34
=========================
 -- Permit the cancellation of a job that is in the process of being 
    requeued.
 -- Ignore the show_flag when getting job, step, node or partition information
    for user root.
 -- Convert some functions to thread-safe versions: getpwnam, getpwuid, 
    getgrnam, and getgrgid to similar functions with "_r" suffix. While no
    failures have been observed, a race condition would in the worst case
    permit a user access to a partition not normally allowed due to the
    AllowGroup specification or the wrong user identified in an accounting
    record. The job would NOT be run as the wrong user.
 -- For PMI only (MPICH2/MVAPICH2) base address to send messages to (the srun)
    upon the address from which slurmd gets the task launch request rather then
    "hostname" where srun executes.
 -- Make test for StateSaveLocation directory more comprehensive.
 -- For jobcomp/script plugin, PROCS environment variable is now the actual
    count of allocated processors rather than the count of processes to 
    be started.

* Changes in SLURM 1.2.33
=========================
 -- Cancelled or Failed jobs will now report their job and step id on exit
 -- Add SPANK items available to get: SLURM_VERSION, SLURM_VERSION_MAJOR,
    SLURM_VERISON_MINOR and SLURM_VERSION_MICRO.
 -- Fixed handling of SIGPIPE in srun. Abort job.
 -- Fix bug introduced to MVAPICH plugin preventing use of TotalView debugger.
 -- Modify slurmctld to get srun/salloc network address based upon the incoming
    message rather than hostname set by the user command (backport of logic in
    SLURM v1.3).

* Changes in SLURM 1.2.32
=========================
 -- LSF only: Enable scancel of job in RootOnly partition by the job's owner.
 -- Add support for sbatch --distribution and --network options.
 -- Correct pending job's wait reason to "Priority" rather than "Resources" if
    required resources are being held in reserve for a higher priority job.
 -- In sched/wiki2 (Moab) report a node's state as "Drained" rather than 
    "Draining" if it has no allocated work (An undocumented Moab wiki option, 
    see CRI ticket #2394).
 -- Log to job's output when it is cancelled or reaches it's time limit (ported
    from existing code in slurm v1.3).
 -- Add support in salloc and sbatch commands for --network option.
 -- Add support for user environment variables that include '\n' (e.g. 
    bash functions).
 -- Partial rewrite of mpi/mvapich plugin for improved scalability.

* Changes in SLURM 1.2.31
=========================
 -- For Moab only: If GetEnvTimeout=0 in slurm.conf then do not run "su" to get
    the user's environment, only use the cache file.
 -- For sched/wiki2 (Moab), treat the lack of a wiki.conf file or the lack 
    of a configured AuthKey as a fatal error (lacks effective security).
 -- For sched/wiki and sched/wiki2 (Maui or Moab) report a node's state as 
    Busy rather than Running when allocated if SelectType=select/linear. Moab
    was trying to schedule job's on nodes that were already allocated to jobs
    that were hidden from it via the HidePartitionJobs in Slurm's wiki.conf.
 -- In select/cons_res improve the resource selection when a job has specified
    a processor count along with a maximum node count.
 -- For an srun command with --ntasks-per-node option and *no* --ntasks count,
    spawn a task count equal to the number of nodes selected multiplied by the 
    --ntasks-per-node value.
 -- In jobcomp/script: Set TZ if set in slurmctld's environment.
 -- In srun with --verbose option properly format CPU allocation information 
    logged for clusters with 1000+ nodes and 10+ CPUs per node.
 -- Process a job's --mail_type=end option on any type of job termination, not
    just normal completion (e.g. all failure modes too).

* Changes in SLURM 1.2.30
=========================
 -- Fix for gold not to print out 720 error messages since they are
    potentally harmful.
 -- In sched/wiki2 (Moab), permit changes to a pending job's required features:
    CMD=CHANGEJOB ARG=<jobid> RFEATURES=<features>
 -- Fix for not aborting when node selection doesn't load, fatal error instead
 -- In sched/wiki and sched/wiki2 DO NOT report a job's state as "Hold" if it's
    dependencies have not been satisfied. This reverses a changed made in SLURM
    version 1.2.29 (which was requested by Cluster Resources, but places jobs 
    in a HELD state indefinitely).

* Changes in SLURM 1.2.29
=========================
 -- Modified global configuration option "DisableRootJobs" from number (0 or 1)
    to boolean (YES or NO) to match partition parameter.
 -- Set "DisableRootJobs" for a partition to match the global parameters value 
    for newly created partitions.
 -- In sched/wiki and sched/wiki2 report a node's updated features if changed
    after startup using "scontrol update ..." command.
 -- In sched/wiki and sched/wiki2 report a job's state as "Hold" if it's 
    dependencies have not been satisfied.
 -- In sched/wiki and sched/wiki2 do not process incoming requests until
    slurm configuration is completely loaded.
 -- In sched/wiki and sched/wiki2 do not report a job's node count after it 
    has completed (slurm decrements the allocated node count when the nodes
    transition from completing to idle state).
 -- If job prolog or epilog fail, log the program's exit code.
 -- In jobacct/gold map job names containing any non-alphanumeric characters 
    to '_' to avoid MySQL parsing problems.
 -- In jobacct/linux correct parsing if command name contains spaces.
 -- In sched/wiki and sched/wiki2 report make job info TASK count reflect the 
    actual task allocation (not requested tasks) even after job terminates.
    Useful for accounting purposes only.

* Changes in SLURM 1.2.28
=========================
 -- Added configuration option "DisableRootJobs" for parameter 
    "PartitionName".  See "man slurm.conf" for details.
 -- Fix for faking a large system to correctly handle node_id in the task
    afffinity plugin for ia64 systems.

* Changes in SLURM 1.2.27
=========================
 -- Record job eligible time in accounting database (for jobacct/gold only).
 -- Prevent user root from executing a job step within a job allocation 
    belonging to another user.
 -- Fixed limiting issue for strings larger than 4096 in xstrfmtcat
 -- Fix bug in how Slurm reports job state to Maui/Moab when a job is requeued
    due to a node failure, but we can't terminate the job's spawned processes.
    Job was being reported as PENDING when it was really still COMPLETING.
 -- Added patch from Jerry Smith for qstat -a output
 -- Fixed looking at the correct perl path for Slurm.pm in torque wrappers.
 -- Enhance job requeue on node failure to be more robust.
 -- Added configuration parameter "DisableRootJobs". See "man slurm.conf" 
    for details.
 -- Fixed issue with account = NULL in Gold job accounting plugin

* Changes in SLURM 1.2.26
=========================
 -- Correct number of sockets/cores/threads reported by slurmd (from
    Par Andersson, National Supercomputer Centre, Sweden).
 -- Update libpmi linking so that libslurm is not required for PMI use
    (from Steven McDougal, SiCortex).
 -- In srun and sbatch, do not check the PATH env var if an absolute pathname 
    of the program is specified (previously reported an error if no PATH).
 -- Correct output of "sinfo -o %C" (CPU counts by node state).

* Changes in SLURM 1.2.25
=========================
 -- Bug fix for setting exit code in accounting for batch script.
 -- Add salloc option, --no-shell (for LSF).
 -- Added new options for sacct output
 -- mvapich: Ensure MPIRUN_ID is unique for all job steps within a job.
    (Fixes crashes when running multiple job steps within a job on one node)
 -- Prevent "scontrol show job" from failing with buffer overflow when a job 
    has a very long Comment field.
 -- Make certain that a job step is purged when a job has been completed.
    Previous versions could have the job step persist if an allocated node
    went DOWN and the slurmctld restarted.
 -- Fix bug in sbcast that can cause communication problems for large files.
 -- Add sbcast option -t/--timeout and SBCAST_TIMEOUT environment variable 
    to control message timeout.
 -- Add threaded agent to manage a queue of Gold update requests for 
    performance reasons.
 -- Add salloc options --chdir and --get-user-env (for Moab).
 -- Modify scontrol update to support job comment changes.
 -- Do not clear a DRAINED node's reason field when slurmctld restarts.
 -- Do not cancel a pending job if Moab or Maui try to start it on unusable nodes.
    Leave the job queued.
 -- Add --requeue option to srun and sbatch (these undocumented options have no
    effect in slurm v1.2, but are legitimate options in slurm v1.3).
 
* Changes in SLURM 1.2.24
=========================
 -- In sched/wiki and sched/wiki2, support non-zero UPDATE_TIME specification
    for GETNODES and GETJOBS commands.
 -- Bug fix for sending accounting information multiple times for same 
    info.  patch from Hongjia Cao (NUDT).
 -- BLUEGENE - try FILE pointer rotation logic to avoid core dump on 
    bridge log rotate
 -- Spread out in time the EPILOG_COMPLETE messages from slurmd to slurmctld
    to avoid message congestions and retransmission.

* Changes in SLURM 1.2.23
=========================
 -- Fix for libpmi to not export unneeded variables like xstr*
 -- BLUEGENE - added per partition dynamic block creation
 -- fix infinite loop bug in sview when there were multiple partitions
 -- Send message to srun command when a job is requeued due to node failure.
    Note this will be overwritten in the output file unless JobFileAppend
    is set in slurm.conf. In slurm version 1.3, srun's --open-mode=append
    option will offer this control for each job.
 -- Change a node's default TmpDisk from 1MB to 0MB and change job's default 
    disk space requirement from 1MB to 0MB.
 -- In sched/wiki (Maui scheduler) specify a QOS (quality of service) by 
    specifying an account of the form "qos-name".
 -- In select/linear, fix bug in scheduling required nodes that already have
    a job running on them (req.load.patch from Chris Holmes, HP).
 -- For use with Moab only: change timeout for srun/sbatch --get-user-env 
    option to 2 secs, don't get DISPLAY environment variables, but explicitly 
    set ENVIRONMENT=BATCH and HOSTNAME to the execution host of the batch script.
 -- Add configuration parameter GetEnvTimeout for use with Moab. See
    "man slurm.conf" for details.
 -- Modify salloc and sbatch to accept both "--tasks" and "--ntasks" as 
    equivalent options for compatibility with srun.
 -- If a partition's node list contains space separators, replace them with 
    commas for easier parsing.
 -- BLUEGENE - fixed bug in geometry specs when creating a block.
 -- Add support for Moab and Maui to start jobs with select/cons_res plugin
    and jobs requiring more than one CPU per task.

* Changes in SLURM 1.2.22
=========================
 -- In sched/wiki2, add support for MODIFYJOB option "MINSTARTTIME=<time>"
    to modify a job's earliest start time.
 -- In sbcast, fix bug with large files and causing sbcast to die.
 -- In sched/wiki2, add support for COMMENT= option in STARTJOB and CANCELJOB
    commands.
 -- Avoid printing negative job run time in squeue due to clock skew.
 -- In sched/wiki and sched/wiki2, add support for wiki.conf option
    HidePartitionJobs (see man pages for details).
 -- Update to srun/sbatch --get-user-env option logic (needed by Moab).
 -- In slurmctld (for Moab) added job->details->reserved_resources field
    to report resources that were kept in reserve for job while it was 
    pending.
 -- In sched/wiki (for Maui scheduler) report a pending job's node feature 
    requirements (from Miguel Roa, BSC).
 -- Permit a user to change a pending job's TasksPerNode specification 
    using scontrol (from Miguel Roa, BSC).
 -- Add support for node UP/DOWN event logging in jobacct/gold plugin
    WARNING: using the jobacct/gold plugin slows the system startup set the
    MessageTimeout variable in the slurm.conf to around 20+.
 -- Added check at start of slurmctld to look for /tmp/slurm_gold_first if
    there, and using the gold plugin slurm will make record of all nodes in
    downed or drained state.

* Changes in SLURM 1.2.21
=========================
 -- Fixed torque wrappers to look in the correct spot for the perl api
 -- Do not treat user resetting his time limit to the current value as
    an error.
 -- Set correct executable names for Totalview when --multi-prog option 
    is used and more than one node is allocated to the job step.
 -- When a batch job gets requeued, record in accounting logs that 
    the job was cancelled, the requeued job's submit time will be 
    set to the time of its requeue so it looks like a different job.
 -- Prevent communication problems if the slurmd/slurmstepd have a 
    different JobAcct plugin configured than slurmctld.
 -- Adding Gold plugin for job accounting
 -- In sched/wiki2, add support for MODIFYJOB option "JOBNAME=<name>"
    to modify a job's name.
 -- Add configuration check for sys/syslog.h and include it as needed.
 -- Add --propagate option to sbatch for control over limit propagation.
 -- Added Gold interface to the jobacct plugin.  To configure in the config
    file specify...  
    JobAcctType=jobacct/gold
    JobAcctLogFile=CLUSTER_NAME:GOLD_AUTH_KEY_FILE:GOLDD_HOST:GOLDD_PORT7112
 -- In slurmctld job record, set begin_time to time when all of a job's
    dependencies are met.

* Changes in SLURM 1.2.20
=========================
 -- In switch/federation, fix small memory leak effecting slurmd.
 -- Add PMI_FANOUT_OFF_HOST environment variable to control how message 
    forwarding is done for PMI (MPICH2). See "man srun" for details.
 -- From sbatch set SLURM_NTASKS_PER_NODE when --ntasks-per-node option is 
    specified.
 -- BLUEGENE: Documented the prefix should always be lower case and the 3
    digit suffix should be uppercase if any letters are used as digits. 
 -- In sched/wiki and sched/wiki2, add support for --cpus-per-task option.
    From Miguel Ros, BSC.
 -- In sched/wiki2, prevent invalid memory pointer (and likely seg fault) 
    for job associated with a partition that has since been deleted.
 -- In sched/wiki2 plus select/cons_res, prevent invalid memory pointer 
    (and likely seg fault) when a job is requeued.
 -- In sched/wiki, add support for job suspend, resume, and modify.
 -- In sched/wiki, add suppport for processor allocation (not just node allocation)
    with layout control.
 -- Prevent re-sending job termination RPC to a node that has already completed 
    the job. Only send it to specific nodes which have not reported completion.
 -- Support larger environment variables 64K instead of BUFSIZ (8k on some 
    systems).
 -- If a job is being requeued, job step create requests will print a 
    warning and repeatedly retry rather than aborting.
 -- Add optional mode value to srun and sbatch --get-user-env option.
 -- Print error message and retry job submit commands when MaxJobCount 
    is reached. From Don Albert, Bull.
 -- Treat invalid begin time specification as a fatal error in sbatch and 
    srun. From Don Albert, Bull.
 -- Validate begin time specification to avoid hours >24, minutes >59, etc.

* Changes in SLURM 1.2.19
=========================
*** NOTE IMPORTANT CHANGE IN RPM BUILD BELOW ****
 -- slurm.spec file (used to build RPMs) was updated in order to support Mock, a
    chroot build environment. See https://hosted.fedoraproject.org/projects/mock/
    for more information. The following RPMs are no longer build by default:
    aix-federation, auth_none, authd, bluegene, sgijob, and switch-elan. Change 
    the RPMs built using the following options in ~/rpmmacros: "%_with_authd 1", 
    "%_without_munge 1", etc. See the slurm.spec file for more details.
 -- Print warning if non-privileged user requests negative "--nice" value on
    job submission (srun, salloc, and sbatch commands).
 -- In sched/wiki and sched/wiki2, add support for srun's --ntasks-per-node 
    option.
 -- In select/bluegene with Groups defined for Images, fix possible memory 
    corruption. Other configurations are not affected. 
 -- BLUEGENE - Fix bug that prevented user specification of linux-image, 
    mloader-image, and ramdisk-image on job submission.
 -- BLUEGENE - filter Groups specified for image not just by submitting 
    user's current group, but all groups the user has access to.
 -- BLUEGENE - Add salloc options to specify images to be loaded (--blrts-image, 
    --linux-image, --mloader-image, and --ramdisk-image).
 -- BLUEGENE - In bluegene.conf, permit Groups to be comma separated in addition 
    to colon separators previously supported.
 -- sbatch will accept batch script containing "#SLURM" options and advise
    changed to "#SBATCH".
 -- If srun --output or --error specification contains a task number rather 
    than a file name, send stdout/err from specified task to srun's stdout/err
    rather than to a file by the same name as the task's number.
 -- For srun --multi-prog option, verify configuration file before attempting 
    to launch tasks, report clear explanation of any configuration file errors.
 -- For sched/wiki2, add optional timeout option to srun's --get-user-env
    parameter, change default timeout for "su - <user> env" from 3 to 8 seconds.
    On timeout, attempt to load env from file at StateSaveLocation/env_cache/<user>.
    The format of this file is the same as output of "env" command. If there
    is no env cache file, then abort the request.
 -- squeue modified for completing job to remove nodes that have already 
    completed the job before applying node filter logic.
 -- squeue formatted output option added for job comment, "%q" (the obvious 
    choices for letters are already in use).
 -- Added configure option --enable-load-env-no-login for use with Moab. If
    set then the user job runs with the environment built without a login
    ("su <user> env" rather than "su - <user> env").
 -- Fix output of "srun -o %C" (allocated CPU count) for running jobs. This was
    broken in 1.2.18 for handling requeue of Moab jobs.
 -- Added logic to mpiexec wrapper to read in the MPIEXEC_TIMEOUT var
 -- Updated qstat wrapper to display information for partitions (-Q) option
 -- NOTE: SLURM should now work directly with Globus using the PBS GRAM.

* Changes in SLURM 1.2.18
=========================
 -- BLUEGENE - bug fix for smap stating passthroughs are used when they aren't
 -- Fixed bug in sview to be able to edit partitions correctly
 -- Fixed bug so in slurm.conf files where SlurmdPort isn't defined things
    work correctly.
 -- In sched/wiki2 and sched/wiki add support for batch job being requeued
    in Slurm either when nodes fail or upon request.
 -- In sched/wiki2 and sched/wiki with FastSchedule=2 configured and nodes 
    configured with more CPUs than actually exist, return a value of TASKS 
    equal to the number of configured CPUs that are allocated to a job rather 
    than the number of physical CPUs allocated.
 -- For sched/wiki2, timeout "srun --get-user-env ..." command after 3 seconds 
    if unable to perform pseudo-login and get user environment variables.
 -- Add contribs/time_login.c program to test how long pseudo-login takes
    for specific users or all users. This can identify users for which Moab 
    job submissions are unable to set the proper environment variables.
 -- Fix problem in parallel make of Slurm.
 -- Fixed bug in consumable resources when CR_Core_Memory is enabled
 -- Add delay in slurmctld for "scontrol shutdown" RPC to get propagated 
    to slurmd daemons.

 -- Add srun support for SLURM_THREADS and PMI_FANOUT environment variables.
 -- Fix support in squeue for output format with left justification of 
    reason (%r) and reason/node_list (%R) output.
 -- Automatically requeue a batch job when a node allocated to it fails
    or the prolog fails (unless --no-requeue or --no-kill option used).
 -- In sched/wiki, enable use of wiki.conf parameter ExcludePartitions to
    directly schedule selected partitions without Maui control.
 -- In sched/backfill, if a job requires specific nodes, schedule other jobs
    ahead of it rather than completely stopping backfill scheduling for that
    partition.
 -- BLUEGENE - corrected logic making block allocation work in a circular 
    fashion instead of linear.
 
* Changes in SLURM 1.2.16
=========================
 -- Add --overcommit option to the salloc command.
 -- Run task epilog from job's working directory rather than directory
    where slurmd daemon started from.

 -- In sched/wiki2, fix bug processing condensed hostlist expressions.
 -- Release contribs/mpich1.slurm.patch without GPL license. 
 -- Fix bug in mvapich plugin for read/write calls that return EAGAIN.
 -- Don't start MVAPICH timeout logic until we know that srun is starting 
    an MVAPICH program.
 -- Fix to srun only allocating number of nodes needed for requested task
    count when combining allocation and step creation in srun.

    be directly schedule by Slurm without Moab control
 -- Optimize load leveling for shared nodes (alloc.patch, contributed 
    by Chris Holmes, HP).
 -- Added PMI_TIME environment variable for user to control how PMI 
    communications are spread out in time. See "man srun" for details.
 -- Added PMI timing information to srun debug mode to aid in tuning.
    Use "srun -vv ..." to see the information.
 -- Added checkpoint/ompi (OpenMPI) plugin (still under development).
 -- Fix bug in load leveling logic added to v1.2.13 which can cause an 
    infinite loop and hang slurmctld when sharing nodes between jobs.

    from the user when excluding nodes, to avoid an error message.
 -- Disable salloc, sbatch and srun -I/--immediate options with 
    Moab scheduler.
 -- Added "contribs" directory with a Perl API and Torque wrappers for Torque 
    to SLURM migration.  This directory should be used to put anything that 
    is outside of SLURM proper such as a different API. Perl APIs contributed 
    by Hongjia Cao (NUDT).
 -- In sched/wiki2: add support for tasklist with node name expressions 
    and task counts (e.g. TASKLIST=tux[1-4]*2:tux[12-14]*4").
 -- In select/cons_res with sched/wiki2: fix bug in task layout logic.
 -- Removed all curses info from the bluegene plugin putting it into smap
    where it belongs.  
 -- Add support for job time limit specification formats: min, min:sec, 
    hour:min:sec, and days-hour:min:sec (formerly only supported minutes).
    Applies to salloc, sbatch, and srun commands.
 -- Improve scheduling support for exclusive constraint list, nodes can 
    now be in more than one constraint specific exclusively for a job
    (e.g. "srun -C [rack1|rack2|rack3|rowB] srun")
 -- Create separate MPICH/MX plugin (split out from MPICH/GM plugin)
 -- Increase default MessageTimeout (in slurm.conf) from 5 to 10 secs.
 -- Fix bug in batch job requeue if node zero of allocation fails to respond 
    to task launch request.
 -- Improve load leveling logic to more evenly distribute the workload 
    (best_load.patch, contributed by Chris Holmes, HP).
 
* Changes in SLURM 1.2.12
=========================
 -- Increase maximum message size from 1MB to 16MB (from Ernest Artiaga, BSC). 
 -- In PMI_Abort(), log the event and abort the entire job step.
 -- Add support for additional PMI functions: PMI_Get_clique_ranks and 
    PMI_Get_clique_size (from Chuck Clouston, Bull).
 -- Report an error when a hostlist comes in appearing to be a box but not 
    formatted in XYZxXYZ format.
 -- Add support for partition configuration "Shared=exclusive". This is 
    equivalent to "srun --exclusive" when select/cons_res is configured.
 -- In sched/wiki2, report the reason for a node being unavailable for the 
    GETNODES command using the CAT="<reason>" field.
 -- In sched/wiki2 with select/linear, duplicate hostnames in HOSTLIST, one
    per allocated processor.
 -- Fix bug in scancel with specific signal and job lacks active steps.
 -- In sched/wiki2, add support for NOTIFYJOB ARG=<jobid> MSG=<message>.
    This sends a message to an active srun command.
 -- salloc will now set SLURM_NPROCS to improve srun's behavior under salloc.
 -- In sched/wiki2 and select/cons_res: insure that Slurm's CPU allocation
    is identical to Moab's (from Ernest Artiaga and Asier Roa, BSC).
 -- Added "scontrol show slurmd" command to status local slurmd daemon.
 -- Set node DOWN if prolog fails on node zero of batch job launch.
 -- Properly handle "srun --cpus-per-task" within a job allocation when 
    SLURM_TASKS_PER_NODE environment varable is not set.
 -- Fixed return of slurm_send_rc_msg if msg->conn_fd is < 0 set errno ENOTCONN
    and return SLURM_ERROR instead of return ENOTCONN

 -- Enable nice file propagation from sbatch command.
 
* Changes in SLURM 1.2.11
=========================
 -- Updated "etc/mpich1.slurm.patch" for direct srun launch of MPICH1_P4
    tasks. See the "README" portion of the patch for details.
 -- Added new scontrol command "show hostlist <hostnames>" to translate a list 
    of hostnames into a hostlist expression (e.g. "tux1,tux2" -> "tux[1-2]")
    and "show hostnames <list>", returns a list of of nodes (one node per line)
    from SLURM hostlist expression or from SLURM_NODELIST environment variable 
    if no hostlist specified.
 -- Add the sbatch option "--wrap".
 -- Add the sbatch option "--get-user-env".

 -- Use SLURM_UMASK environment variable (if set) at job submit time as umask 
    for spawned job.
 -- Correct some format issues in the man pages (from Gennero Oliva, ICAR).
 -- Added support for parallel make across an existing SLURM allocation
    based upon GNU make-3.81. Patch is in "etc/make.slurm.patch".
 -- Added '-b' option to sbatch for easy MOAB trasition to sbatch instead of
    srun.  Option does nothing in sbatch.
 -- Changed wiki2's handling of a node state in Completing to return 'busy' 
    instead of 'running' which matches slurm version 1.1

* Changes in SLURM 1.2.10
=========================
 -- Fix race condititon in jobacct/linux with use of proctrack/pgid and a
    realloc issue inside proctrack/linux
 -- Added MPICH1_P4 plugin for direct launch of mpich1/p4 tasks using srun
    and a patched version of the mpi library. See "etc/mpich1.slurm.patch".
    NOTE: This is still under development and not ready for production use.

* Changes in SLURM 1.2.9
========================
 -- Add new sinfo field to sort by "%E" sorts by the time associated with a 
    node's state (from Prashanth Tamraparni, HP).
 -- In sched/wiki: fix logic for restarting backup slurmctld.
 -- Preload SLURM plugins early in the slurmstepd operation to avoid
    multiple dlopens after forking (and to avoid a glibc bug
    that leaves dlopen locks in a bad state after a fork).
 -- Added MPICH1_P4 patch to launch tasks using srun rather than rsh and
    automatically generate mpirun's machinefile based upon the job's 
    allocation.    See "etc/mpich1.slurm.patch".
 -- BLUEGENE - fix for overlap mode to mark all other base partitions as used
    when creating a new block from the file to insure we only use the base 
    partitions we are asking for.

* Changes in SLURM 1.2.8
========================
 -- Added mpi/mpich1_shmem plugin.

========================
 -- BLUEGENE - code to make it so you can make a 36x36x36 system.  
    The wiring should be correct for a system with x-dim of 1,2,4,5,8,13
    in emulation mode.  It will work with any real system no matter the size.
 -- Major re-write of jobcomp/script plugin: fix memory leak and 
    general code clean-up.
 -- Add ability to change MaxNodes and ExcNodeList for pending job 
    using scontrol.
 -- Purge zombie processes spawned via event triggers.
 -- Add support for power saving mode (experimental code to reduce voltage
    and frequency on nodes that stay in the IDLE state, for more information

 -- In forward logic fix to check if the forwarding node recieves a connection
    but doesn't ever get the message from the sender (network issue or
    something) also check to make sure if we get something back we make sure
    we account for everything we sent out before we call it good.
 -- Another fix to make sure steps with requested nodes have correct cpus
    accounted for and a fix to make sure the user can't allocate more 
    cpus than the have requested.

* Changes in SLURM 1.2.3
========================
 -- Cpuset logic added to  task/affinity, from Don Albert (Bull) and
    Moe Jette (LLNL).  The /dev/cpuset file system must be mounted and 
    set "TaskPluginParam=cpusets" in slurm.conf to enable.
 -- In sched/wiki2, fix possible overflow in job's nodelist, from 
    Ernest Artiaga, BSC.
 -- Defer creation of new job steps until a suspended job is resumed.
 -- In select/linear - fix for potential stack corruption bug.

    and SLURM_TASK_EPILOG. patch.1.2.0-pre11.070201.envproepilog from 
    Dan Palermo, HP.
 -- Documenation update. patch.1.2.0-pre11.070201.mchtml from Dan Palermo, HP.

* Changes in SLURM 1.2.0-pre15
==============================
 -- Fix for another spot where the backup controller calls switch/federation
    code before switch/federation is initialized.

* Changes in SLURM 1.2.0-pre14
==============================
 -- In sched/wiki2, clear required nodes list when a job is requeued.
    Note that the required node list is set to every node used when 
    a job is started via sched/wiki2.
 -- BLUEGENE - Added display of deallocating blocks to smap and other tools. 
 -- Make slurmctld's working directory be same as SlurmctldLogFile (if any),
    otherwise StateSaveDir (which is likely a shared directory, possibly 
    making core file identification more difficult).
 -- Fix bug in switch/federation that results in the backup controller
    aborting if it receives an epilog-complete message.

* Changes in SLURM 1.2.0-pre13
==============================
 -- Fix for --get-user-env.

    state on real systems and total block config on emulation systems.
 -- Major update to Slurm's PMI internal logic for better scalability.
    Communications now supported directly between application tasks via 
    Slurm's PMI library. Srun sends single message to one task on each node
    and that tasks forwards key-pairs to other tasks on that nodes. The old 
    code sent key-pairs directly to each task. 
    NOTE: PMI applications must re-link with this new library.
 -- For multi-core support: Fix task distribution bug and add automated 
    tests, patch.1.2.0-pre11.070111.plane from Dan Palermo (HP).

==============================
 -- Add multi-core options to slurm_step_launch API.
 -- Add man pages for slurm_step_launch() and related functions.
 -- Jobacct plugin only looks at the proctrack list instead of the entire
    list of processes running on the node. Cutting down a lot of unnecessary
    file opens in linux and cutting down the time to query the procs by
    more than half.
 -- Multi-core bug fix, mask re-use with multiple job steps,
    patch.1.2.0-pre10.061214.affinity_stepid from Dan Palermo (HP).
 -- Modify jobacct/linux plugin to completely eliminate open /proc files.
 -- Added slurm_sched_plugin_reconfig() function to re-read config files.
 -- BLUEGENE - --reboot option to srun, salloc, and sbatch actually works.
 -- Modified step context and step launch APIs.

* Changes in SLURM 1.2.0-pre10
==============================
 -- Fix for sinfo node state counts by state (%A and %F output options).
 -- Add ability to change a node's features via "scontrol update". NOTE: 
    Update slurm.conf also to preserve changes over slurmctld restart or 
    reconfig.
    NOTE: Job and node state information can not be preserved from earlier 
          versions.
 -- Added new slurm.conf parameter TaskPluginParam.
 -- Fix for job requeue and credential revoke logic from Hongjia Cao (NUDT).
 -- Fix for incorrectly generated masks for task/affinity plugin,
    patch.1.2.0-pre9.061207.bitfmthex from Dan Palermo (HP).

    patch.1.2.0-pre9.061211.avail_cpuspertask from Dan Palermo (HP).
 -- BLUEGENE - Added --reboot option to srun, salloc, and sbatch commands.
 -- Add "scontrol listpids [JOBID[.STEPID]]" support.
 -- Multi-core support patches, fixed SEGV and clean up output for large 
    task counts, patch.1.2.0-pre9.061212.cpubind_verbose from Dan Palermo (HP).
 -- Make sure jobacct plugin files are closed before exec of user tasks to 
    prevent problems with job checkpoint/restart (based on work by 
    Hongjia Cao, NUDT).

* Changes in SLURM 1.2.0-pre9
=============================
 -- Fix for select/cons_res state preservation over slurmctld restart,
    patch.1.2.0-pre7.061130.cr_state from Dan Palermo.
 -- Validate product of socket*core*thread count on node registration rather 
    than individual values. Correct values will need to be specified in slurm.conf 
    with FastSchedule=1 for correct multi-core scheduling behavior.

* Changes in SLURM 1.2.0-pre8
=============================
 -- Modity job state "reason" field to report why a job failed (previously 
    previously reported only reason waiting to run). Requires cold-start of 
    slurmctld (-c option).
 -- For sched/wiki2 job state request, return REJMESSAGE= with reason for 
    a job's failure.
 -- New FastSchedule configuration parameter option "2" means to base 
    scheduling decisions upon the node's configuration as specified in 
    slurm.conf and ignore the node's actual hardware configuration. This 
    can be useful for testing. 
 -- Add sinfo output format option "%C" for CPUs (active/idle/other/total).
    Based upon work by Anne-Marie Wunderlin (BULL).
 -- Assorted multi-core bug fixes (patch1.2.0-pre7.061128.mcorefixes).
 -- Report SelectTypeParameters from "scontrol show config".
 -- Build sched/wiki plugin for Maui Scheduler (based upon new sched/wiki2 
    code for Moab Scheduler).
 -- BLUEGENE - changed way of keeping track of smaller partitions using 
    ionode range instead of quarter nodecard notation. 
    (i.e. bgl000[0-3] instead of bgl000.0.0)
 -- Patch from Hongjia Cao (EINPROGRESS error message change)
 -- Fix for correct requid for jobacct plugin
 -- Added subsec timing display for sacct

* Changes in SLURM 1.2.0-pre7
=============================
 -- BLUEGENE - added configurable images for bluegene block creation.
 -- Plug a bunch of memory leaks.
 -- Support processors, core, and physical IDs that are not in numeric 
    order (in slurmd to gathering node state information, based on patch
    by Don Albert, Bull).
 -- Fixed bug with aix not looking in the correct dir for the proctrack
    include files
 -- Removed global_srun.* from common merged it into srun proper
 -- Added bluegene section to troubleshooting guide (web page). 
 -- NOTE: Requires cold-start when moving from 1.2.0-pre6, save state 
    info for jobs changed.
 -- BLUEGENE - Changed logic for wiring bgl blocks to be more maintainable.
    (Haven't tested on large system yet, works on 2 base partition system)
 -- Do not read the select/cons_res state save file if slurmctld is 
    cold-started (with the "-c" option).

* Changes in SLURM 1.2.0-pre6
=============================
 -- Maintain actually job step run time with suspend/resume use.
 -- Allow slurm.conf options to appear multiple times.  SLURM will use the
    last instance of any particular option.
 -- Add version number to node state save file. Will not recover node 
    state information on restart from older version.
 -- Add logic to save/restore multi-core state information.
 -- Updated multi-core logic to use types uint16_t and uint32_t instead 
    of just type int.

 -- Add support for Portable Linux Processor Affinity (PLPA, see
    http://www.open-mpi.org/software/plpa).
 -- When a job epilog completes on all non-DOWN nodes, immediately purge
    it's job steps that lack switch windows. Needed for LSF operation. 
    Based upon slurm.hp.node_fail.patch.
