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
========================

code before switch/federation is initialized.
* Changes in SLURM 1.2.0-pre14
==============================

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

Danny Auble
committed

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).
* Changes in SLURM 1.2.0-pre11
==============================

-- Add man pages for slurm_step_launch() and related functions.
Danny Auble
committed

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.

* 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).
-- Make mask_cpu options of srun and slaunch commands not requeue prefix
of "0x". patch.1.2.0-pre9.061208.srun_maskparse from Dan Palermo (HP).
-- Add -c support to the -B automatic mask generation for multi-core
support, patch.1.2.0-pre9.061208.mcore_cpuspertask from Dan Palermo (HP).

=============================
-- 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".

slurmctld and srun launch command. This is done with a tree type
algorithm. Spawn and batch mode work the same as before. New slurm.conf
variable TreeWidth=50 is default. This is the number of threads per
-- Configuration parameter HeartBeatInterval is depracated. Now used half
of SlurmdTimeout and SlurmctldTimeout for communications to slurmd and
slurmctld daemons repsectively.
-- Add hash tables for select/cons_res plugin (Susanne Balle, HP,
patch_02222006).

the number of requested tasks.
-- sched/backfill to schedule around jobs that are hung in a completing
state.

reconfig by saving and restoring a hostlist of nodes still completing
the job.
* Changes in SLURM 1.0.15
=========================
-- In srun, reset stdin to blocking mode (if it was originally blocking before
we set it to O_NONBLOCK) on exit to avoid trouble with things like running
srun under a bash shell in an emacs *shell* buffer.
-- Fix srun race condition that occasionally causes segfaults at shutdown
-- Fix obscure locking issues in log.c code.
-- Explicitly close IO related sockets. If an srun gets "stuck", possibly
because of unkillable tasks in its job step, it will not hold many TCP
sockets in the CLOSE_WAIT state.
-- Increase the SLURM protocol timeout from 5 seconds to 10 seconds.
(In 1.2 there will be a slurm.conf parameter for this, rather than having
it hardcoded.)
* Changes in SLURM 1.0.14
