Specifying exclusive resources
An exclusive resource may be used in the resource requirement string of any placement
or scheduling command, such as
bsub, lsplace, lsrun, or lsgrun. An exclusive
resource is a special resource that is assignable to a host. This host will not receive a job
unless that job explicitly requests the host. For example, use the following command to
submit a job requiring the exclusive resource
bigmem:
% bsub -R "bigmem" myjob
Jobs will not be submitted to the host with the bigmem resource unless the command
uses the
-R option to explicitly specify "bigmem".
To configure an exclusive resource, first define a static Boolean resource in
lsf.shared. For example:
Begin Resource
...
bigmem Boolean () ()
End Resource
Assign the resource to a host in the Host section of lsf.cluster.cluster_name.
Prefix the resource name with an exclamation mark (!) to indicate that the resource is
exclusive to the host. For example:
Begin Host
HOSTNAME model type server r1m pg tmp RESOURCES RUNWINDOW
...
hostE ! ! 1 3.5 () () (linux !bigmem) ()
...
End Host
