In the above script, the #BSUB... lines are more than just comments in this Bourne shell script. They are also LSF "bsub" directives. The first two #BSUB directives tell LSF that the batch queue is "atlas-t3" and the wall time limit is 120 minutes. Please always specify a wall time. Otherwise, your jobs will be killed after 30 minutes (wall time). The third #BSUB directive is optional. It tells LSF that the job wants to run on RHEL6 platform ("rhel60") with cvmfs ("cvmfs") and outbound internet connection ("inet"), and that the job needs up to 5GB of space under /scratch, 1000MB of RAM (these are advises to the LSF scheduler, not caps or limits).
