7.4.7 Submitting a Job from a Non-HP XC Host
You can submit a job from a non-HP XC host to the HP XC system. This can be accomplished
by adding a resource requirement string to the LSF command line. A resource requirement
string describes the resources a job needs. LSF uses resource requirements to select hosts for
remote execution and job execution. LSF then runs the job on a host that meets the specified
resource requirements.
To submit a job from a non-HP XC host to the HP XC system, use the LSF -R option, and
the HP XC host type SLINUX64 (defined in lsf.shared ) in the job submission resource
requirement string. The necessary resource requirement string to submit a job from a non-HP
XC host is specified as follows:
-R "type=SLINUX64"
