NEWS

 -- Do not install /etc/init.d/slurm or /etc/init.d/slurmdbd on AIX systems.
 -- BLUEGENE - fixed check for small blocks if a node card of a midplane is
    in an error state other jobs can still run on the midplane on other
    nodecards.
 -- BLUEGENE - Check to make sure job killing is in the active job table in
    DB2 when killing the job.
 -- Correct logic to support ResvOverRun configuration parameter.
 -- Get --acctg-freq option working for srun and salloc commands.
 -- Fix sinfo display of drained nodes correctly with the summarize flag.
 -- Fix minor memory leaks in slurmd and slurmstepd.
 -- Better error messages for failed step launch.
 -- Modify srun to insure compatability of the --relative option with the node
    count requested.

* Changes in SLURM 2.1.6-2
==========================
 -- In sched/wiki2 - Fix logic in support of Moab being able to identify
    preemptable jobs.
 -- Applied fixes to a debug4 message in priority_multifactor.c sent in by
    Per Lundqvist
 -- BLUEGENE - Fixed issue where incorrect nodecards could be picked when
    looking at combining small blocks to make a larger small block.

* Changes in SLURM 2.1.6
========================
 -- For newly submitted jobs, report expected start time in squeue --start as
    "N/A" rather than current time.
 -- Correct sched/backfill logic so that it runs in a more timely fashion.
 -- Fixed issue if running on accounting cache and priority/multifactor to
    initialize the root association when the database comes back up.
 -- Emulated BLUEGENE - fixed issue where blocks weren't always created
    correctly when loading from state.  This does not apply to a real
    bluegene system, only emulated.
 -- Fixed bug when job is completing and its cpu_cnt would be calculated
    incorrectly, possibly resulting in an underflow being logged.
 -- Fixed bug where if there are pending jobs in a partition which was
    updated to have no nodes in it the slurmctld would dump core.
 -- Fixed smap and sview to display partitions with no nodes in them.
 -- Improve configure script's logic to detect LUA libraries.
 -- Fix bug that could cause slurmctld to abort if select/cons_res is used AND a
    job is submitted using the --no-kill option AND one of the job's nodes goes
    DOWN AND slurmctld restarts while that job is still running.
 -- In jobcomp plugins, job time limit was sometimes recorded improperly if not
    set by user (recorded huge number rather than partition's time limit).

* Changes in SLURM 2.1.5
========================
 -- BLUEGENE - Fixed display of draining nodes for sinfo -R.
 -- Fixes to scontrol and sview when setting a job to an impossible start time.
 -- Added -h to srun for help.
 -- Fix for sacctmgr man page to remove erroneous 'with' statements.
 -- Fix for unpacking jobs with accounting statistics, previously it appears
    only steps were unpacked correctly, for the most case sacct would only
    display this information making this fix a very minor one.
 -- Changed scontrol and sview output for jobs with unknown end times from
    'NONE' to 'Unknown'.
 -- Fixed mysql plugin to reset classification when adding a
    previously deleted cluster.
 -- Permit a batch script to reset umask and have that propagate to tasks
    spawed by subsequent srun. Previously the umask in effect when sbatch was
    executed was propagated to tasks spawed by srun.
 -- Modify slurm_job_cpus_allocated_on_node_id() and
    slurm_job_cpus_allocated_on_node() functions to not write explanation of
    failures to stderr. Only return -1 and set errno.
 -- Correction in configurator.html script. Prolog and Epilog were reversed.
 -- BLUEGENE - Fixed race condition where if a nodecard has an error on an
    un-booted block when a job comes to use it before the state checking
    thread notices it which could cause the slurmctld to lock up on a
    non-dynamic system.
 -- In select/cons_res with FastSchedule=0 and Procs=# defined for the node,
    but no specific socket/core/thread count configured, avoid fatal error if
    the number of cores on a node is less than the number of Procs configured.
 -- Added ability for the perlapi to utilize opaque data types returned from
    the C api.
 -- BLUEGENE - made the perlapi get correct values for cpus per node,
    Previously it would give the number of cpus per cnode instead of midplane.
 -- BLEUGENE - Fixed issue where if a block being selected for a job to use
    and during the process a hardware failure happens, previously the block
    would still be allowed to be used which would fail or requeue the job
    depending on the configuration.
 -- For SPANK job environment, avoid duplicate "SPANK_" prefix for environment
    set by sbatch jobs.
 -- Make squeue select jobs on hidden partitions when requesting more than one.
 -- Avoid automatically cancelling job steps when all of the tasks on some node
    have gracefully terminated.

* Changes in SLURM 2.1.4
========================
 -- Fix for purge script in accounting to use correct options.
 -- If SelectType=select/linear and SelectTypeParameters=CR_Memory fix bug that
    would fail to release memory reserved for a job if "scontrol reconfigure"
    is executed while the job is in completing state.
 -- Fix bug in handling event trigger for job time limit while job is still
    in pending state.
 -- Fixed display of Ave/MaxCPU in sacct for jobs. Steps were printed
    correctly.
 -- When node current features differs from slurm.conf, log the node names
    using a hostlist expression rather than listing individual node names.
 -- Improve ability of srun to abort job step for some task launch failures.
 -- Fix mvapich plugin logic to release the created job allocation on
    initialization failure (previously the failures would cancel job step,
    but retain job allocation).
 -- Fix bug in srun for task count so large that it overflows int data type.
 -- Fix important bug in select/cons_res handling of ntasks-per-core parameter
    that was uncovered by a bug fixed in v2.1.3. Bug produced fatal error for
    slurmctld: "cons_res: cpus computation error".
 -- Fix bug in select/cons_res handling of partitions configured with
    Shared=YES. Prior logic failed to support running multiple jobs per node.

* Changes in SLURM 2.1.3-2
==========================
 -- Modified spec file to obsolete pam_slurm when installing
    the slurm-pam_slurm rpm.

* Changes in SLURM 2.1.3-1
==========================
 -- BLUEGENE - Fix issues on static/overlap systems where if a midplane
    was drained you would not be able to create new blocks on it.
 -- In sched/wiki2 (for Moab): Add excluded host list to job information
    using new keyword "EXCLUDE_HOSTLIST".
 -- Correct slurmd reporting of incorrect socket/core/thread counts.
 -- For sched/wiki2 (Moab): Do not extend a job's end time for suspend/resume
    or startup delay due to node boot time. A job's end time will always be
    its start time plus time limit.
 -- Added build-time option (to configure program) of --with-pam_dir to
    specify the directory into which PAM modules get installed, although it
    should pick the proper directory by default. "make install" and "rpmbuild"
    should now put the pam_slurm.so file in the proper directory.
 -- Modify PAM module to link against SLURM API shared library and use exported
    slurm_hostlist functions.
 -- Do not block new jobs with --immediate option while another job is in the
    process of being requeued (which can take a long time for some node failure
    modes).
 -- For topology/tree, log invalid hostnames in a single hostlist expression
    rather than one per line.
 -- A job step's default time limit will be UNLIMITED rather than partition's
    default time limit. The step will automatically be cancelled as part of the
    job termination logic when the job's time limit is reached.
 -- sacct - fixed bug when checking jobs against a reservation
 -- In select/cons_res, fix support for job allocation with --ntasks_per_node
    option. Previously could allocate too few CPUs on some nodes.
 -- Adjustment made to init message to the slurmdbd to allow backwards
    compatibility with future 2.2 release. YOU NEED TO UPGRADE SLURMDBD
    BEFORE ANYTHING ELSE.
 -- Fix accounting when comment of down/drained node has double quotes in it.

* Changes in SLURM 2.1.2
========================
 -- Added nodelist to sview for jobs on non-bluegene systems
 -- Correction in value of batch job environment variable SLURM_TASKS_PER_NODE
    under some conditions.
 -- When a node silently fails which is already drained/down the reason
    for draining for the node is not changed.
 -- Srun will ignore SLURM_NNODES environment variable and use the count of
    currently allocated nodes if that count changes during the job's lifetime
    (e.g. job allocation uses the --no-kill option and a node goes DOWN, job
    step would previously always fail).
 -- Made it so sacctmgr can't add blank user or account.  The MySQL plugin
    will also reject such requests.
 -- Revert libpmi.so version for compatibility with SLURM version 2.0 and
    earlier to avoid forcing applications using a specific libpmi.so version to
    rebuild unnecessarily (revert from libpmi.so.21.0.0 to libpmi.so.0.0.0).
 -- Restore support for a pending job's constraints (required node features)
    when slurmctld is restarted (internal structure needed to be rebuilt).
 -- Removed checkpoint_blcr.so from the plugin rpm in the slurm.spec since
    it is also in the blcr rpm.
 -- Fixed issue in sview where you were unable to edit the count
    of jobs to share resources.
 -- BLUEGENE - Fixed issue where tasks on steps weren't being displayed
    correctly with scontrol and sview.
 -- BLUEGENE - fixed wiki2 plugin to report correct task count for pending
    jobs.
 -- BLUEGENE - Added /etc/ld.so.conf.d/slurm.conf to point to the
    directory holding libsched_if64.so when building rpms.
 -- Adjust get_wckeys call in slurmdbd to allow operators to list wckeys.

* Changes in SLURM 2.1.1
========================
 -- Fix for case sensitive databases when a slurmctld has a mixed case
    clustername to lower case the string to easy compares.
 -- Fix squeue if job is completing and failed to print remaining
    nodes instead of failed message.
 -- Fix sview core when searching for partitions by state.
 -- Fixed setting the start time when querying in sacct to the
    beginning of the day if not set previously.
 -- Defined slurm_free_reservation_info_msg and slurm_free_topo_info_msg
    in common/slurm_protocol_defs.h
 -- Avoid generating error when a job step includes a memory specification and
    memory is not configured as a consumable resource.
 -- Patch for small memory leak in src/common/plugstack.c
 -- Fix sview search on node state.
 -- Fix bug in which improperly formed job dependency specification can cause
    slurmctld to abort.
 -- Fixed issue where slurmctld wouldn't always get a message to send cluster
    information when registering for the first time with the slurmdbd.
 -- Add slurm_*_trigger.3 man pages for event trigger APIs.
 -- Fix bug in job preemption logic that would free allocated memory twice.
 -- Fix spelling issues (from Gennaro Oliva)
 -- Fix issue when changing parents of an account in accounting all children
    weren't always sent to their respected slurmctlds until a restart.
 -- Restore support for srun/salloc/sbatch option --hint=nomultithread to
    bind tasks to cores rather than threads (broken in slurm v2.1.0-pre5).
 -- Fix issue where a 2.0 sacct could not talk correctly to a 2.1 slurmdbd.
 -- BLUEGENE - Fix issue where no partitions have any nodes assigned them to
    alert user no blocks can be created.
 -- BLUEGENE - Fix smap to put BGP images when using -Dc on a Blue Gene/P
    system.
 -- Set SLURM_SUBMIT_DIR environment variable for srun and salloc commands to
    match behavior of sbatch command.
 -- Report WorkDir from "scontrol show job" command for jobs launched using
    salloc and srun.
 -- Update correctly the wckey when changing it on a pending job.
 -- Set wckeyid correctly in accounting when cancelling a pending job.
 -- BLUEGENE - critical fix where jobs would be killed incorrectly.
 -- BLUEGENE - fix for sview putting multiple ionodes on to nodelists when
    viewing the jobs tab.

* Changes in SLURM 2.1.0
========================
 -- Improve sview layout of blocks in use.
 -- A user can now change the dimensions of the grid in sview.
 -- BLUEGENE - improved startup speed further for large numbers of defined
    blocks
 -- Fix to _get_job_min_nodes() in wiki2/get_jobs.c suggested by Michal Novotny
 -- BLUEGENE - fixed issues when updating a pending job when a node
    count was incorrect for the asked for connection type.
 -- BLUEGENE - fixed issue when combining blocks that are in ready states to
    make a larger block from those or make multiple smaller blocks by
    splitting the larger block.  Previously this would only work with block
    in a free state.
 -- Fix bug in wiki(2) plugins where if HostFormat=2 and the task list is
    greater than 64 we don't truncate.  Previously this would mess up Moab
    by sending a truncated task list when doing a get jobs.
 -- Added update slurmctld debug level to sview when in admin mode.
 -- Added logic to make sure if enforcing a memory limit when using the
    jobacct_gather plugin a user can no longer turn off the logic to enforce
    the limit.
 -- Replaced many calls to getpwuid() with reentrant uid_to_string()
 -- The slurmstepd will now refresh it's log file handle on a reconfig,
    previously if a log was rolled any output from the stepd was lost.
