As an example for GNU parallel we are printing out all combinations of the letters A,B and C with D, E and F in parallel.

[leonhard@euler07 ~]$ module load new gcc/4.8.2 gnu_parallel/20140622
[leonhard@euler07 ~]$ bsub -n 2 -W 0:10 -R "rusage[mem=20]" "parallel echo ::: A B C ::: D E F"
Generic job.
Job <35259068> is submitted to queue <normal.4h>.
[leonhard@euler07 ~]$ bjobs
JOBID      USER       STAT  QUEUE      FROM_HOST   EXEC_HOST   JOB_NAME   SUBMIT_TIME
35259068   leonhard   PEND  normal.4h  euler07                 *::: D E F Jan  9 08:13
[leonhard@euler07 ~]$ bjobs
JOBID      USER       STAT  QUEUE      FROM_HOST   EXEC_HOST   JOB_NAME   SUBMIT_TIME
35259068   leonhard   RUN   normal.4h  euler07     2*e2121     *::: D E F Jan  9 08:13
[leonhard@euler07 ~]$ bjobs
No unfinished job found
[leonhard@euler07 ~]$ tail -n 9 lsf.o35259068
