Syntax

Valid values

unique

Default

Notes

At job submission, LSF reserves the correct number of processors and PAM starts only 1 process per host. For example, to reserve 32 processors and run on 4 processes per host, resulting in the use of 8 hosts:

bsub -n 32 -R "span[ptile=4]" pam yourOpenMPJob

Where defined

This parameter can alternatively be set as an environment variable. For example:

setenv LSF_PAM_HOSTLIST_USE unique
