| RELEASE NOTES FOR SLURM VERSION 1.1.10 |
| 30 August 2006 |
| |
| * There is a new version of the Wiki scheduler plugin to interface with |
| the Maui Scheduler and Moab. It can be accessed with the slurm.conf |
| parameter "SchedulerType=sched/wiki2" (it will replace "sched/wiki" |
| in SLURM version 1.2, but will co-exist in version 1.1.10+). Key |
| differences include: |
| - Node and job data returned is correct (several errors in old plugin) |
| - Node data includes partition information (CCLASS field) |
| - Improved error handling |
| - Support added for configuration file ("wiki.conf" in same directory |
| as "slurm.conf" file, see "man wiki.conf" for details) |
| - Support added for job suspend/resume |
| - Authentication of communications now supported |
| - Improved performance |
| - Memory leaks fixed |

| RELEASE NOTES FOR SLURM VERSION 1.1 |
| 15 May 2006 |
| See the file NEWS for more details. |
| |
| * Added support for file broadcast to allocated compute nodes (see |
| "man sbcast") |
| * Added support for different executable files and arguments by task, based |
| upon a configuration file (see "man srun" option "--multi-prog") |
| * Added support for hierarchical communications. Added new configuration |
| option "TreeWidth" (see "man slurm.conf") |
| * Major re-write of accounting logic, some sacct format changes (see |
| "man sacct") |
| * Slurm.conf option "JobAcctType=jobacct/log" is no longer supported, |
| use "JobAcctType=jobacct/none", "JobAcctType=jobacct/linux" or |
| "JobAcctType=jobacct/aix" (see "man slurm.conf") |
| * Support large (over 2 GB) files on 32-bit Linux systems |
| * Change in support for test suite: 'testsuite/expect/globals.example' |
| is now 'testsuite/expect/globals' and you can override variable |
| settings with a new file 'testsuite/expect/globals.local' |
| * Job suspend now sends SIGTSTP, sleep(1), sends SIGSTOP for better |
| MPI support |
| * Change time format in job completion logging (JobCompType=jobcomp/filetxt) |
| from "MM/DD HH:MM:SS" to "YYYY-MM-DDTHH:MM:SS", conforming with the ISO8601 |
| standard format |
| * Add support for ISO8601 time format for all SLURM commands by defining |
| "CFLAGS=-DISO8601" before configuration. NOTE: This may break Moab, |
| Maui, and/or LSF schedulers. |
| * Sacct can get accounting information about currently running jobs and |
| job steps (see "man sacct") |
| * Added support for mapping "%h" in configured SlurmdLog to the hostname |
| (see "man slurm.conf") |
| * Add PropagatePrioProcess to control propagation of a user's nice value |
| to spawned tasks (see "man slurm.conf") |
| * Add support for srun to set PMI communications address (see "man srun" |
| option "--ctrl-comm-ifhn") |
| * Re-wrote slurm.conf parsing logic. A "NodeName" may now occur only once |
| in a slurm.conf file. If you want to make nodes DOWN in slurm.conf, use |
| the new "DownNodes" keyword (see "man slurm.conf") |
| * Added support for XCPU task launch mechanism |
| * Gracefully handle request to submit batch job from within an existing |
| batch job |
| * Warn user attempting to create a job allocation from within an existing |
| job allocation |
| * Add new function to get a job's time limit (see "man slurm_get_rem_time") |
| * "JobAcctType=jobacct/log" |
| * Slurm.conf parameter "InactiveLimit" is not enforced for RootOnly partitions |
| (see "man slurm.conf") |
| * Added support for memory affinity (see "man srun" option "--mem_bind") |
| * Configuration parameter "HeartBeatInterval" is deprecated. Now uses half |
| of "SlurmdTimeout" and "SlurmctldTimeout" for communications to slurmd and |
| slurmctld daemons respectively (see "man slurm.conf") |
| * Support node-specific resource limits controlled via Pluggable Authentication |
| Mechanism (PAM, see "man slurm.conf" parameter "UsePAM") |
| * Support stackable plugins to be called before and/or after execution of |
| each task spawned as part of a user's job step (see "man slurm.conf" |
| parameter "PlugStackConfig") |
| * Slurm.conf paramter "JobAcctLoc" has been changed to "JobAcctLogFile" |
| |
| BLUEGENE SPECIFIC UPDATES |
| * Resource allocations based upon c-node counts rather than base partition |
| counts, all commands and configuration parameters effected |
| * Added support for overlapping blocks (see "man bluegene.conf") |
| * Added support for dynamic block creation (see "man bluegene.conf") |
| * Added support for srun -w option |
| * Before assigning a job to a block the plugin will check the base |
| partitions to make sure they aren't in error state |
