This file describes changes in recent versions of SLURM. It primarily
documents those changes that are of interest to users and admins.
* Changes in SLURM 1.2.2
========================
-- srun --get-user-env now sends su's stderr to /dev/null
-- MPICHGM support bug fixes from Ernest Artiaga, BSC.
-- Support longer hostlist strings, from Ernest Artiaga, BSC.
-- Srun to use env vars for SLURM_PROLOG, SLURM_EPILOG, SLURM_TASK_PROLOG,
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.
-- Set SLURM_DIST_CYCLIC = 1 (needed for HP MPI, slurm.hp.env.patch).
* 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.
* Changes in SLURM 1.2.0-pre12
==============================
Danny Auble
committed
-- BLUEGENE - Added correct node info for sinfo and sview for viewing
allocated nodes in a partition.
-- BLUEGENE - Added state save on slurmctld shutdown of blocks in an error
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 multi-core options to slurm_step_launch API.
-- Add man pages for slurm_step_launch() and related functions.
Danny Auble
committed
-- 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).
-- 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 bug in MASK_CPU calculation,
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).

(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
=============================

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.
-- Race condition for forwarding logic fix from Hongjia Cao

http://www.open-mpi.org/software/plpa).

it's job steps that lack switch windows. Needed for LSF operation.
Based upon slurm.hp.node_fail.patch.
