-LLNL-SPECIFIC RELEASE NOTES FOR SLURM VERSION 2.0
-19 February 2009
+LLNL CHAOS-SPECIFIC RELEASE NOTES FOR SLURM VERSION 2.1
+16 October 2009
 
-For processor-scheduled clusters (*not* allocating whole nodes to jobs):
-Set "DefMemPerCPU" and "MaxMemPerCPU" as appropriate to restrict memory 
-available to a job. Also set "JobAcctGatherType=jobacct_gather/linux"
-for enforcement (periodic sampling of memory use by the job).  You can change 
-said sampling rate from the default (every 30 seconds) by setting the 
-"JobAcctGatherFrequency" option to a different number of seconds in 
-the slurm.conf.
+This lists only the most significant changes from Slurm v2.0 to v2.1
+with respect to Chaos systems. See the file RELEASE_NOTES for other
+changes.
 
-For InfiniBand switch systems, set TopologyType=topology/tree in slurm.conf
-and add switch topology information to a new file called topology.conf. 
-Options used are SwitchName, Switches, and Nodes. The SwitchName is any 
-convenient name for bookkeeping purposes only. For example:
-# Switch Topology Information
-SwitchName=s0 Nodes=tux[0-11]
-SwitchName=s1 Nodes=tux[12-23]
-SwitchName=s2 Nodes=tux[24-35]
-SwitchName=s3 Switches=s[0-2]
+For system administrators:
+* The pam_slurm Pluggable Authentication Module for SLURM previously
+  distributed separately has been moved within the main SLURM distribution
+  and is packaged as a separate RPM.
+* Configuration parameter MaxTasksPerNode has been added to control how many 
+  tasks that the slurmd can launch.
+* Added command "sacctmgr show problems" to display problems in the accounting 
+  database (e.g. accounts with no users, users with no UID, etc.).
 
-Remove the "preserve-env.so" SPANK plugin. The functionality is now
-directly in SLURM.
+Mostly for users:
+* Added -"-signal=<int>@<time>" option to salloc, sbatch and srun commands to
+  notify programs before reaching the end of their time limit.
+* Added a --detail option to "scontrol show job" to display the cpu/memory
+  allocation informaton on a node-by-node basis.
+* Add new job wait reason, ReqNodeNotAvail: Required node is not available 
+  (down or drained).
 
-SLURM version 2.0 must use a database daemon (slurmdbd) at version 2.0
-or higher. While we are testing version 2.0, set "AccountingStoragePort=????".
-Once we upgrade the production slurmdbd to version 2.0, this change will
-not be required.  You can likewise test 1.3.7+ clusters with the same port 
-since 2.0 slurmdbd will talk to 1.3.7+ SLURM.
-
-SLURM state files in version 2.0 are different from those of version 1.3.
-After installing SLURM version 2.0, plan to restart without preserving 
-jobs or other state information. While SLURM version 1.3 is still running, 
+SLURM state files in version 2.1 are different from those of version 2.1.
+After installing SLURM version 2.1, plan to restart without preserving 
+jobs or other state information. While SLURM version 2.0 is still running, 
 cancel all pending and running jobs (e.g.
 "scancel --state=pending; scancel --state=running"). Then stop and restart 
 daemons with the "-c" option or use "/etc/init.d/slurm startclean".
