This file describes changes in recent versions of SLURM. It primarily
documents those changes that are of interest to users and admins.
-- Added SLURM_VERSION_NUMBER and removed SLURM_API_VERSION from
slurm/slurm.h.
Danny Auble
committed
-- Added support to handle communication with SLURM 2.1 clusters. Job's
should not be lost in the future when upgrading to higher versions of
SLURM.
-- Added withdeleted options for listing clusters, users, and accounts
-- Remove PLPA task affinity functions due to that package being deprecated.
-- Preserve current partition state information and node Feature and Weight
information rather than use contents of slurm.conf file after slurmctld
restart with -R option or SIGHUP. Replace information with contents of
slurm.conf after slurmctld restart without -R or "scontrol reconfigure".
See RELEASE_NOTES file fore more details.
-- Modify SLURM's PMI library (for MPICH2) to properly execute an executable
program stand-alone (single MPI task launched without srun).
-- Made GrpCPUs and MaxCPUs limits work for select/cons_res.
Danny Auble
committed
-- Moved all SQL dependant plugins into a seperate rpm slurm-sql. This
should be needed only where a connection to a database is needed (i.e.
where the slurmdbd is running)
-- Add command line option "no_sys_info" to PAM module to supress system
logging of "access granted for user ...", access denied and other errors
will still be logged.
Danny Auble
committed
-- sinfo -R now has the user and timestamp in separate fields from the reason.
* Changes in SLURM 2.1.3
=============================
* 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
=============================
Danny Auble
committed

clustername to lower case the string to easy compares.
Danny Auble
committed
-- 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.
Danny Auble
committed
-- 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

-- Patch for small memory leak in src/common/plugstack.c
-- 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

-- 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 childern
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.
-- 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.
Danny Auble
committed
-- 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.
Danny Auble
committed
-- 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()
Danny Auble
committed
-- 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.
* Changes in SLURM 2.1.0-pre9
=============================
-- Added the "scontrol update SlurmctldDebug" as the preferred alternative to
the "scontrol setdebug" command.
Danny Auble
committed

the block are set correctly in accounting as not in error.
Danny Auble
committed
-- Fixed issue where if slurmdbd is not up qos' are set up correctly for
-- scontrol, squeue, sview all display the correct node, cpu count along with
correct corresponding nodelist on completing jobs.
-- Patch (Mark Grondona) fixes serious security vulnerability in SLURM in
the spank_job_env functionality.
-- Improve spank_job_env interface and documentation
-- Add ESPANK_NOT_LOCAL error code to spank_err_t
-- Made the #define DECAY_INTERVAL used in the priority/multifactor plugin
a slurm.conf variable (PriorityCalcPeriod)
Danny Auble
committed
-- Added new macro SLURM_VERSION for use in autoconf scripts to determine
current version of slurm installed on system when building against the api.
-- Patch from Matthieu Hautreux that adds an entry into the error file when
a job or step receives a TERM or KILL signal.
Danny Auble
committed
-- Make it so env var SLURM_SRUN_COMM_HOST is overwritten if already in
* Changes in SLURM 2.1.0-pre8
=============================
-- Rearranged the "scontrol show job" output into functional groupings
-- Change the salloc/sbatch/srun -P option to -d (dependency)
-- Removed the srun -d option; must use srun --slurmd-debug instead
-- When running the mysql plugin natively MUNGE errors are now eliminated
when sending updates to slurmctlds.
-- Check to make sure we have a default account before looking to
fill in default association.
-- Accounting - Slurmctld and slurmdbd will now set uids of users which were
created after the start of the daemons on reconfig. Slurmdbd will
attempt to set previously non-existant uids every hour.
Danny Auble
committed
-- Patch from Aaron Knister and Mark Grondona, to parse correctly quoted
#SBATCH options in a batch script.
-- job_desc_msg_t - in, out, err have been changed to std_in, std_out,

as a keyword.
-- Changed the type of addr to struct sockaddr_in in _message_socket_accept()
Danny Auble
committed
in sattach.c, step_launch.c, and allocate_msg.c, and moved the function
into a common place for all the calls since the code was very similar.
-- proctrack/lua support has been added see contribs/lua/protrack.lua
-- replaced local gtk m4 test with AM_PATH_GTK_2_0
-- changed AC_CHECK_LIB to AC_SEARCH_LIBS to avoid extra libs in
compile lines.

ReturnToService=2
Danny Auble

restarting or reconfiguring.
* Changes in SLURM 2.1.0-pre6
=============================

name of NULL rather than returning no information about the node so that
node index information is still valid.
-- When querying database for jobs in certain state and a time period is

committed
given only jobs in that state during the period will be returned,
previously if a time period was given in sacct jobs eligible to run or
running would be displayed, which is still the default if no states are
