ChangeLog

2011-03-22 Mark Grondona <mgrondona@llnl.gov>

	* : tag v0.17.

	* cpuset/cpuset.c :
	  Remove code supporting slurm version < 2.1.0.

	* Makefile :
	  Remove oom-detect.so.

	* slurm-spank-plugins.spec :
	  Remove oom-detect.so.

2011-01-12 Mark Grondona <mgrondona@llnl.gov>

	* : tag v0.16.

	* slurm-spank-plugins.spec :
	  Package lua-schedutils with slurm-spank-plugins-lua.

	* lua/lua-schedutils, lua/Makefile :
	  Added lua 'schedutils' module for use in spank-lua modules.

2011-01-10 Mark Grondona <mgrondona@llnl.gov>

	* : tag v0.15.

	* auto-affinity.c : Fix up bug in CPU affinity enable.

	* auto-affinity.c : Add repeat operator to masks= option.
	  e.g. 0xf0*4 == 0xf0,0xf0,0xf0,0xf0.

2010-10-28 Mark Grondona <mgrondona@llnl.gov>

	* : tag v0.14.

2010-10-27 Mark Grondona <mgrondona@llnl.gov>

	* auto-affinity.c : If int(ncpus / ntasks) > 1, use this result as
	  the value of cpus_per_task even when the number of CPUs is not
	  an exact multiple of the number of tasks. A new option,
	  multiples_only given in the plugstack.conf will reinstate the
	  old behavior.

	* auto-affinity.c : If user provided -c, --cpus-per-task of >= 2
	  to SLURM, and the user did not explicitly set cpus_per_task/cpt
	  in the auto-affinity module, then use the SLURM value of
	  cpus_per_task as if it had been passed to auto-affinity.

2010-08-19 Mark Grondona <mgrondona@llnl.gov>

	* : tag v0.13.

2010-08-11 Mark Grondona <mgrondona@llnl.gov>

	* auto-affinity.c : Add 'cpus' and 'masks' options to allow
	  users to explicitly specify CPU affinity for tasks.

2010-03-08 Mark Grondona <mgrondona@llnl.gov>

	* : tag v0.12.

	* cpuset/util.c : Fix unchecked return code from slurm_load_jobs(3)
	  which could lead to segv in various components, including
	  slurmstepd and cpuset_release_agent.

	* cpuset/cpuset.c : Fix signed comparison of unsinged variable.

2010-03-07 Mark Grondona <mgrondona@llnl.gov>

	* : tag v0.11.

2010-03-06 Mark Grondona <mgrondona@llnl.gov>

	* lua/lua.c :
	  Avoid lua stack overflow.

2010-03-06 Mark Grondona <mgrondona@llnl.gov>

	* cpuset/pam_slurm_cpuset.c :
	  Remove unecessary logging.

	* cpuset/Makefile, cpuset/cpuset.c, cpuset/slurm.c,
	  cpuset,slurm.h, cpuset/util.c, cpuset/pam_slurm_cpuset.c :

	  Instead link to liblslurm directly.

	* cpuset/cpuset.c :
	  Add get_nodeid() call.

	* cpuset/cpuset.c :
	  Move slurmstepd process back to user cpuset after last task
	  has exited. This prevents a hanging slurmstepd from consuming
	  CPUs when SLURM job is marked as completed.

2010-03-05 Mark Grondona <mgrondona@llnl.gov>

	* use-env/log_msg.c :

	  Use slurm_load_job in preference to slurm_load_jobs where
	  appropriate. 

2009-10-30 Matthieu Hautreux <matthieu.hautreux@cea.fr>
	
	* setsched.c : add setsched plugin which enables to enforce
	  a particular kernel scheduling policy for tasks spawned

2009-05-12 Jim Garlick <garlick@llnl.gov>

	* : tag v0.7.

	* private-mount.c : Insert a statfs(1) call after the mount.
	  This is a trick to cause lustre to wait for all its servers to

	* : tag v0.6.

	* private-mount.c : New.

2009-03-13 Mark Grondona <mgrondona@llnl.gov>

	* : tag v0.5.

	* slurm-spank-plugins.spec :
	  Remove preserve-env.so from RPM, this functionality is
	  now available in SLURM 1.4.x. The plugin remains as a
	  reference. Also remove oom-detect.so, from the base 
	  slurm-spank-plugins RPM. It belongs only in the llnl RPM.

	* auto-affinity.c :
	  Use the physical layout of CPUs as documented under
	  /sys/devices/system/cpu/cpu*/topology/ to assign CPUs
	  to tasks, instead of assuming that logical CPU IDs
	  match the actual CPU layout.

2008-10-09 Mark Grondona <mgrondona@llnl.gov>

	* : tag v0.4.

	* preserve-env.c :
	  Fix crash in slurmstepd when dealing with environment entries
	  larger than 64 bytes. Make all environment variable name and
	  value buffers (except for save_SLURM*) dynamic.

2008-10-06 Mark Grondona <mgrondona@llnl.gov>

	* : tag v0.3.

	* slurm-spank-plugins.spec :
	  Obsoletes: chaos-spankings.

2008-10-03 Mark Grondona <mgrondona@llnl.gov>

	  Removed.

	* slurm-spank-plugins.spec :
	  New spec file for slurm-spank-plugins RPM. 

	* META :
	  Rename project to slurm-spank-plugins.

	* Makefile, cpuset/Makefile, 
	  overcommit-memory/Makefile, 
	  use-env/Makefile :
	  Update to build system to not build cpuset and oom-detect
	  plugins by default, and to support "make install" target.


2008-09-25 Mark Grondona <mgrondona@llnl.gov>

	* : tag v0.34.

	* preserve-env.c :
	  Added.

	* auto-affinity.c :
	  Check current CPU mask in task context as well as in
	  post opt and abort auto-set of affinity if CPU masks
	  have changed. This probably means something else is 
	  controlling CPU affinity (or cpusets).

2008-09-11 Mark Grondona <mgrondona@llnl.gov>

	* : tag v0.33.

	* cpuset/log.c :
	  Fix off-by-one use of log level.

	* cpuset/conf-parser.y :
	  Change message about opening config file from verbose to debug.

	* cpuset/cpuset.c, cpuset/create.c, cpuset/util.c :
	  Change locking methodology to use global lockfile in /var/lock
	  instead of using lockfile under /dev/cpuset/slurm. Advisory
	  locks are dropped if any fd open against a locked file is closed,
	  not just the original fd. Since libcpuset opens all files under
	  the /dev/cpuset heirarchy, no file within that fs is usable
	  as a lockfile for slurm cpuset.

2008-09-10 Mark Grondona <mgrondona@llnl.gov>

	* use-env/use-env.c :
	  Fix generation of SLURM_CMDLINE. (Was accidentally generated
	  in reverse order).

2008-08-21 Mark Grondona <mgrondona@llnl.gov>

	* : tag v0.32.

	* oom-detect.c :
	  Add 'do_syslog' parameter, which, when true,
	  sends a message via syslog(3) when any task of
	  a job step is thought to have been terminated by
	  the OOM killer.

2008-08-19 Mark Grondona <mgrondona@llnl.gov>

	* : tag v0.31.

	* oom-detect.c :
	  Delay slightly if an OOM killed task is detected.
	  This should give srun more time to recv the error
	  message.

2008-08-04 Mark Grondona <mgrondona@llnl.gov>

	* : tag v0.30.

	* cpuset/conf-parser.y, cpuset/cpuset.c :
	  Improve config file parse errors.

	* auto-affinty.c :
	  Update --auto-affinity=help.

2008-07-29 Mark Grondona <mgrondona@llnl.gov>
	
	* : tag v0.29.

	  Document `tasks' option to --use-cpusets.

	* cpuset/cpuset.c, cpuset/util.c  :
	  Add --use-cpusets=tasks support to constrain tasks to
	  their own cpusets under the job step cpuset.

	* : tag v0.26

	* cpuset/README :
	  Add documentation for --use-cpusets option.

	* cpuset/cpuset.c, cpuset/util.h, cpuset/util.c,
	  cpuset/nodemap.c, cpuset/Makefile :
	  Add spank user option --use-cpusets to optionally allow
	  per-job-step cpusets, which are created under the overall
	  job cpuset.

	* auto-affinity.so : 
	  Move check for cpuset to after user options have been 
	  processed, in case cpuset was changed. Open cpuset related
	  proc files with O_RDONLY instead of O_RDWR.

	* : tag v0.25.

	* chaos-spankings.spec :
	  Add cpuset subpackage for SLURM cpuset plugin,
	  /etc/init.d/slurm-cpuset init script, and 
	  /sbin/cpuset_release_agent binary.

	* cpsuet/cpuset.init :
	  Add initscript to mount /dev/cpuset.

	* cpuset/nodemap.c :
	  Allocate CPUs from nodes in reverse for best-fit and
	  worst-fit, but in order for first-fit.

	* cpuset/cpuset.c :
	  Be sure to call slurm_cpuset_create() early in plugin,

	  of memory nodes. Change "idle-first" options to 
	  !idle-1st, idle-1st=gt, idle-1st=mult, idle-1st=no.

	* Makefile :
	  Add cpuset to subdirs.

	* cpuset/Makefile, cpuset/util.h, cpuset/util.c,
	  cpuset/nodemap.h, cpuset/nodemap.c, cpuset/cpsuet.c,
	  cpuset/test.c, cpuset/release-agent.c :
	  Add initial version of SLURM cpuset.so module.

	* auto-affinity.c : 
	  Allow auto-affinity to work when running inside a cpuset.
	  Map CPUs as chosen for CPU affinity back to actual CPUs
	  available to tasks inside their cpuset. (Plugin should
	  work the same as before, except that the number of available
	  CPUs is adjusted to the number of CPUs in the cpuset).

2008-06-10 Mark Grondona <mgrondona@llnl.gov>

	* : tag v0.24.

	* Makefile :
	  auto-affinity.so now needs to link against libslurm.

	* auto-affinity.c :
	  If SLURM_JOB_CPUS_PER_NODE is not set, fall back to querying
	  slurm controller for necessary information. This is only
	  used in exclusive_only mode, and is a temporary solution
	  until the env var above is set for all SLURM jobs.

2008-06-10 Mark Grondona <mgrondona@llnl.gov>

	* : tag v0.23.

	* auto-affinity.c :

	  Add `exclusive' option to auto-affinity plugin, which, when
	  used, will disable auto-affinity when the running job does
	  not have exclusive access to the node.

2008-05-15 Mark Grondona <mgrondona@llnl.gov>

	* addr-no-randomize.c : 
	  Added plugin to set ADDR_NO_RANOMIZE personality on 
	  processes, thus disabling address space randomization.

	  overcommit-memory/overcommit.c, overcommit-memory/overcommit.h :
	  Also adjust overcommmit_ratio when overcommit-memory plugin is 
	  used (mainly for the "no overcommit" case). Reset original 
	  value when the last user exits.

	* : tag v0.18.

2007-02-02 Mark Grondona <mgrondona@llnl.gov>
	
	* : tag v0.17. 

2007-02-02 Mark Grondona <mgrondona@llnl.gov>

	* overcommit-memory.c, overcommit-memory/overcommit-memory.c

	  overcommit-memory/util.c, lib/fd.c, lib/fd.h  : 
	  Move overcommit-memory source into its own dir. 
	  Plugin now uses a shared memory file to track current users
	  and restores default overcommit policy when the last user
	  exits. Supply a utility, overcommit-util, to clean up state
	  of shared memory file, query current users, etc.

	* chaos-spankings.spec : 
	  Updates for changes in overcommit-memory plugin.

2007-02-02 Mark Grondona <mgrondona@llnl.gov>

	* auto-affinity.c : Force enable auto-affinity if any user option is

	* use-env : 
	  Moved use-env plugin into its own directory.
	  Complete redesign of use-env parser implemented with lex & yacc. 
	  - Support for double-quoted strings.
	  - Added support for conditional if/else if/else/endif blocks.
	  - Added support for expansion of symbols with $ID and ${ID}
	    constructs. Symbols are use-env keywords, locally defined
		symbols, or environment variables (searched in that order).
	  - Added support for keywords SLURM_NNODES, SLURM_NPROCS, SLURM_JOBID,
	    SLURM_STEPID for testing attributes of the current job.

	    system settings.
	  - User default file is always called "default"
	  - Allow a list of names to be specified to --use-env, e.g.
	    --use-env=mvapich,test. The settings are applied in order
	    i.e. test after mvapich.

	* use-env.c : 
	  - Check for slurm_spank_local_user_init support from SPANK,
	    and if it exists, read environment overrides in that 
	    callback instead of in spank_init and option processing hooks.

	 * list.c, list.h, split.c, split.h : Added.
