Nyx currently has 8 compute nodes na01-08 with Gclisi Isilon as the main file system. The login node is 'nyx'.

Differences in LSF Configuration between Nyx and luna

1. When specifying RAM for LSF jobs, specify GB of RAM per task (slot) on Nyx (unlike luna, where RAM is specified per job).

2. Job may have -W (maximum execution Walltime). Please do not use -We on Nyx.

3. There is no /swap on compute nodes. Memory usage is enforced by cgroups so jobs never swap. A job will be terminated if memory usage exceeds its LSF specification.

4. There is no iounits resource on Juno.

5. To check jobs which are DONE or status EXIT, use "bhist -l JobID" or "bhist -n 0 -l JobID". bacct is also available. "bjobs -l JobID" only shows RUNNING and PEND jobs.
