Differences in LSF configuration on Juno vs Luna

1. GPFS and OS reserve 12GB of RAM per host on Juno CentOS7 hosts. Usable memory for LSF jobs: Total RAM - 12 GB.
2. Memory (GB) is per slot/task on Juno. Memory(GB) is per job on Luna.
3. All jobs should have -W (Walltime) on Juno. LSF enforces it. Please, don't use -We on Juno.
4. To check job information for DONE or EXIT jobs use "bhist -l JobID" or "bhist -n 0 -l JobID". Also "bacct" can be used. " bjobs -l JobID" should be used only for RUNNING or PEND jobs.
5. There is no "iounits" resource on Juno.
