HFSS15: bsub Arguments

The LSF bsub command has a large number of options that may be used to control the submission process. Only a few options which are often used with Ansoft jobs are mentioned here. The following options may be used to submit serial or parallel LSF jobs.

-n min_proc, max_proc or -n min_proc

Submits a parallel job, specifying the number of processors (or slots) required for the job. Here, min_proc is the minimum number of processors, and max_proc is the maximum number of processors. If no maximum is specified, then exactly min_proc processors are requested. If PARALLEL_SCHED_BY_SLOT=Y in lsb.params, this option specifies the number of slots required to run the job, not the number of processors. If the -n command line option is not specified, then the job is submitted as a serial batch job.

-R "span[ptile=n]"

There are many ways to use the -R "res_req" option to the bsub command. We only cover -R "span[ptile=n]" here, because this option is very useful for Ansoft jobs. When this option is specified, the LSF scheduler will allocate n processors (or slots) on each host to this job, even if more processors are available on the host.

-x

All hosts running this job operate in exclusive execution mode. The job will only run on a host having no other jobs running on that host. No other batch jobs will be started on a host while this job is running on that host. The -m host_name option of the lsrun or lsgrun commands may be used to force an interactive job to run on a host in exclusive mode. The -m host_name option of the brun command may be used to force a batch job to run on a host in exclusive mode.

See the LSF documentation for a complete list of options for the bsub command.
