cray.conf - Slurm configuration file for the Cray-specific
information
cray.conf is an ASCII file which defines parameters used by
Slurm's select/cray plugin in support of Cray systems. 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.
The default configuration parameters will work properly in a typical
installation and this file will not be required.
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 configuration parameters available include:
- AlpsEngine=<engine_version>
- Communication protocol version number to be used between Slurm and
ALPS/BASIL. The default value is BASIL's response to the ENGINE query. Use
with caution: Changes in ALPS communications which are not recognized by
Slurm could result in loss of jobs. Currently supported values include
1.1, 1.2.0, 1.3.0, 3.1.0, 4.0, 4.1.0, 4.2.0, 5.0, 5.1, 5.2 or
"latest". A value of "latest" will use the most
current version of Slurm's logic and can be useful for validation with new
versions of ALPS.
- AlpsDir=<pathname>
- Fully qualified pathname of the directory in which ALPS is installed. The
default value is /usr.
- apbasil=<pathname>
- Fully qualified pathname to the apbasil command. The default value is
/usr/bin/apbasil.
- apbasilTimeout=<seconds>
- How many seconds to wait for the apbasil command to complete before
killing it. By default, wait indefinitely
- apkill=<pathname>
- Fully qualified pathname to the apkill command. The default value is
/usr/bin/apkill.
- NoAPIDSignalOnKill=Yes
- When set to yes this will make it so the slurmctld will not signal the
apid's in a batch job. Instead it relies on the rpc coming from the
slurmctld to kill the job to end things correctly.
- SDBdb=<dbname>
- Name of the ALPS database. The default value is XTAdmin.
- SDBhost=<dbname>
- Hostname of the database server. The default value is sdb.
- SDBpass=<password>
- Password used to access the ALPS database. The default value is NULL,
which will load the password from the my.cnf file.
- SDBport=<port_number>
- Port used to access the ALPS database. The default value is 0.
- SDBuser=<user_name>
- Name of user used to access the ALPS database. The default value is NULL,
which will load the user name from the my.cnf file.
- SubAllocate=Yes
- Only allocate requested node resources instead of the whole node. In both
cases the user will be charged for the entire node.
- SyncTimeout=<seconds>
- Slurm does not normally schedule jobs while its job or node state
information is out of synchronization with that of ALPS. This parameter
specifies a maximum time to defer job scheduling while waiting for
consistent state. The inconsistent state might be caused by a variety of
hardware or software failures and proceeding could result in more
failures. The default value is 3600 (one hour). A value of zero will wait
indefinitely for consistent state.
