This example covers adding IB as a Boolean resource to LSF:

Type Boolean: Either a nodes has it (1) or doesnt (0)

Add the Resource to LSF

• In file /etc/cfm/templates/lsf/default.lsf.shared, add to following line to the RESOURCE stanza.

Begin Resource
RESOURCENAME  TYPE    INTERVAL INCREASING  DESCRIPTION        # Keywords
...
ib            Boolean     ()    ()          (Infiniband Availability)
End Resource

Assign Resource to Hosts

• In file /etc/cfm/templates/lsf/default.lsf.cluster, add the following after the XXX_lsfmc_XXX tag. NOTE: Nodes with the IB tag have to be listed individually.

Begin   Host
HOSTNAME  model    type        server r1m  mem  swp  RESOURCES    #Keywords
...
XXX_lsfmc_XXX   !   !   1   3.5   ()   ()   (mg)
cn109   !       !       1       3.5     ()      ()      (openmpi mpich2 mvapich ib)
cn110   !       !       1       3.5     ()      ()      (openmpi mpich2 mvapich ib)
cn111   !       !       1       3.5     ()      ()      (openmpi mpich2 mvapich ib)
cn112   !       !       1       3.5     ()      ()      (openmpi mpich2 mvapich ib)
