NAME

       wiki.conf - Slurm configuration file for wiki and wiki2 scheduler plugins

DESCRIPTION

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 or at execution time by setting the SLURM_CONF environment variable. 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. 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.

HidePartitionNodes
Identifies partitions whose nodes are not to be reported to Moab/Maui. Nodes which are configured
only in hidden partitions will not be accounted for or otherwise visible to Moab/Maui. Any
partitions included here will normally also be included in the ExcludePartitions and
HidePartitionJobs parameters. 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 occurring 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
