NAME

cray.conf - Slurm configuration file for the Cray-specific information

DESCRIPTION

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.
