-- BLUEGENE SPECIFIC - added load function to smap to load an already
exsistant bluegene.conf file.
-- Fix bug in sacct: If user requests specific job or job step ID,

-- Removes the slurmd's use of SysV shared memory. Instead the slurmd
communicates with the slurmstepd processes through the slurmstepd's
new named unix domain socket. The "stepd_api" is used to talk to the
slurmstepd (src/slurmd/common/stepd_api.[ch]).
-- Bluegene specific - bluegene block allocator will find most any
partition size now. Added support to start at any point in smap
to request a partition instead of always starting at 000.
-- Bluegene specific - Support to smap to down or bring up nodes in
configure mode. Added commands include allup, alldown,
up [range], down [range]

D-HH:MM:SS per POSIX standards document.
-- Treat scontrol update request without any requested changes as an
error condition.

simple messaging protocol.
-- Added task plugin and use task prolog/epilog(s).
-- New slurmd_step functionality added. Fork exec instead of using shared
memory. Not completely tested.
-- BGL small partition logic in place in plugin and smap. Scheduler needs
to be rewritten to handle multiple partitions on a single node. No
documentation written on process yet.
-- If running select/bluegene plugin without access to BGL DB2, then
full-system bglblock is of system size defined in bluegene.conf.
* Changes in SLURM 0.7.0-pre1

TaskProlog, TaskEpilog, TaskPlugin; srun --task-prolog, --task-epilog).
* Changes in SLURM 0.6.11
=========================
-- Fix bug in sinfo partition sorting order.
-- Fix bugs in srun use of #SLURM options in batch script.

=========================
-- Fix for slurmd job termination logic (could hang in COMPLETING state).
-- Sacct bug fixes: Report correct user name for job step, show "uid.gid"
as fifth field of job step record (Andy Riebs, slurm.hp.sacct_uid.patch).
-- Add job_id to maui scheduler plugin start job status message.
-- Fix for srun's handling of null characters in stdout or stderr.

=============================
-- Remove debugging xassert in switch/federation that were accidentally
committed
-- Make slurmd step manager retry slurm_container_destroy() indefinitely
instead of giving up after 30 seconds. If something prevents a job
step's processes from being killed, the job will be stuck in the
completing until the container destroy succeeds.
* Changes in SLURM 0.6.0-pre7
=============================
-- Disable localtime_r() calls from forked processes (semaphore set
in another pthread can deadlock calls to localtime_r made from
the forked process, this will be properly fixed in the next
major release of SLURM).

srun --cpus-per-task option
-- Generate error file to note prolog failures.
* Changes in SLURM 0.6.0-pre5
=============================
-- Modify sfree (BGL command) so that --all option no longer requires
an argument.

nodes that the user can't access, otherwise there are holes in
its maps).
-- Added module to parse time string (src/common/parse_time.c) for
future use.
-- Fix BlueGene hostlist processing for non-rectangular prisms and
add string length checking.
-- Modify orphan batch job time calculation for BGL to account for
slowness when booting many bglblocks at the same time.

-- Modify squeue --user option to accept not only user names, but also
user IDs.
