How to run multiple jobs on the same partition without a reboot for each run?


This option is obsolete when using llrun to submit interactive LoadLeveler jobs.


If you want to run a sequence of jobs using the same partition and don't want to reboot the partition every time a new job starts you can call the mpirun command using the -nofree option:
    mpirun [-np <p> | -partition <part>] -nofree ......

If a partition has been dynamically allocated with -np (resulting in the allocation of a partition named RMP....) and -nofree, use this partition name in all consecutive runs:

    mpirun -partition RMP... [-nofree] ......

Use llstat to find the name of the partition, which is allocated to you.

CAUTION:

After using -nofree once (!) on a partition the partition remains allocated to the user (and accounted), even if -nofree is left out on mpirun.

So at the end of multiple mpiruns a partition must be freed with:

    freepartition <partname>
