NAME
wiki.conf - Slurm configuration file for wiki and wiki2 scheduler
plugins
DESCRIPTION
/etc/wiki.conf is an ASCII file which describes wiki and wiki2
scheduler specific SLURM configuration information. The file location
can be modified at system build time using the DEFAULT_SLURM_CONF
parameter. The file will always be located in the same directory as the
slurm.conf file.
Parameter names are case insensitive. Any text following a "#" in the
configuration file is treated as a comment through the end of that
line. The size of each line in the file is limited to 1024 characters.
Changes to the configuration file take effect upon restart of SLURM
daemons, daemon receipt of the SIGHUP signal, or execution of the
command "scontrol reconfigure" unless otherwise noted.
The overall configuration parameters available include:
AuthKey
Authentication key for communications. This should be no more
than a 32-bit unsigned integer and match the KEY configured in
the moab-private.cnf file (for the Moab Scheduler) or the
--with-key= value used to configure the Maui Scheduler.
EHost Name the computer on which Moab server executes. It is used in
establishing a communications path for event notification. By
default EHost will be identical in value to the ControlAddr
configured in slurm.conf. Not applicable to wiki plugin, only
the wiki2 plugin.
EHostBackup
Name the computer on which the backup Moab server executes. It
is used in establishing a communications path for event
notification. By default EHostBackup will be identical in value
to the BackupAddr configured in slurm.conf. Not applicable to
wiki plugin, only the wiki2 plugin.
EPort Port to be used to notify Moab of events (job submitted to
SLURM, job terminates, etc.). This numeric value should match
EPORT configured in the moab.cnf file. Not applicable to wiki
plugin, only the wiki2 plugin.
ExcludePartitions
Identifies partitions whose jobs are to be scheduled directly by
SLURM rather than Moab/Maui. This only effects jobs which are
submitted using SLURM commands (i.e. srun, salloc or sbatch, NOT
msub from Moab). These jobs will be scheduled on a
First-Come-First-Served basis directly by SLURM. Note that
SLURM recognizes jobs submitted via msub based upon the value
FirstJobId configured in slurm.conf. Set the values MINJOBID
and MAXJOBID in moab.cfg accordingly. For example MINJOBID=1,
MAXJOBID=65535 and FirstJobId=65536. Jobs submitted using msub
will have job ID values in the range of 1 and 65535 while jobs
submitted directly using SLURM commands will have a job ID of
65536 or higher. Moab/Maui controls for resource reservation,
fair share scheduling, etc. will not apply to the initiation of
these jobs. While Moab/Maui will not control the initiation of
jobs in these partitions, it will account for and report the
jobs. If more than one partition is to be scheduled directly by
SLURM, use a comma separator between their names. This may
provide faster response times than Moab/Maui scheduling.
HidePartitionJobs
Identifies partitions whose jobs are not to be reported to
Moab/Maui. These jobs will not be accounted for or otherwise
visible to Moab/Maui. Any partitions listed here must also be
listed in ExcludePartitions. This only effects jobs which are
submitted using SLURM commands (i.e. srun, salloc or sbatch,
NOT msub from Moab). If more than one partition is to have its
jobs hidden, use a comma separator between their names.
HostFormat
Controls the format of host lists exchanged between SLURM and
Moab. The default value is "0". Not applicable to wiki plugin,
only the wiki2 plugin.
0 No data compression. Each host name is listed
individually.
1 SLURM hostlist expressions are exchanged with task counts
(e.g. "tux[0-16]*2") in job state information and job
initiation requests.
2 SLURM hostlist expressions are used to report node state
information.
JobAggregationTime
This is used to avoid notifying Moab of large numbers of events
occuring about the same time. If an event occurs within this
number of seconds since Moab was last notified of an event,
another notification is not sent. This should be an integer
number of seconds. The default value is 10 seconds. The value
should match JOBAGGREGATIONTIME configured in the moab.cnf file.
Not applicable to wiki plugin, only the wiki2 plugin.
JobPriority
Controls initial job priority. The default value is "hold".
Not applicable to wiki plugin, only the wiki2 plugin.
run Job permitted to run directly under SLURM’s control
hold Hold all incoming jobs until Moab or Maui tell them to
run
