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.
