NAME

       gres.conf - Slurm configuration file for generic resource management.

DESCRIPTION

       /etc/gres.conf  is  an  ASCII file which describes the configuration of
       generic resources on each  compute  node.  Each  node  must  contain  a
       gres.conf  file if generic resources are to be scheduled by SLURM.  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:

       Count  Number  of  resources  of this type available on this node.  The
              default value is set to the number of File values specified  (if
              any),  otherwise  the default value is one. A suffix of "K", "M"
              or "G" may be used to mulitply the number by  1024,  1048576  or
              1073741824 respectively.

       CPUs   Specify  the  CPU  index numbers for the specific CPUs which can
              use this resources. For example, it may be  strongly  preferable
              to  use  specific  CPUs  with  specific  devices (e.g. on a NUMA
              architecture). Multiple CPUs may  be  specified  using  a  comma
              delimited list or a range may be specified using a "-" separator
              (e.g. "0,1,2,3" or "0-3").  If not specified, then any  CPU  can
              be  used  with  the  resources.  If any CPU can be used with the
              resources, then do not specify  the  CPUs  option  for  improved
              speed in the SLURM scheduling logic.

       File   Fully  qualified  pathname of the device files associated with a
              resource.  The name can include a numberic range  suffix  to  be
              interpretted  by SLURM (e.g. File=/dev/nvidia[0-3]).  This field
              is  generally  required  if  enforcement  of  generic   resource
              allocations  is  to  be  supported  (i.e.  prevents a users from
              making use of resources allocated to a different user).  If File
              is specified then Count must be either set to the number of file
              names specified or not set (the default value is the  number  of
              files specified).  NOTE: If you specify the File parameter for a
              resource on some node, the option must be specified on all nodes
              and SLURM will track the assignment of each specific resource on
              each node. Otherwise SLURM will only track a count of  allocated
              resources rather than the state of each individual device file.

       Name   Name  of  the  generic  resource.  Any desired name may be used.
              Each generic resource has an optional plugin which  can  provide
              resource-specific  options.   Generic  resources  that currently
              include an optional plugin are:

              gpu    Graphics Processing Unit

              nic    Network Interface Card
