IBM Spectrum LSF ELIM for IBM Spectrum Scale

IBM Spectrum Scale is a scale-out high performance global parallel file system. For product information, see the IBM Spectrum Scale website.

You can configure LSF to monitor IBM Spectrum Scale and to check the health of the file system. This is performed by two ELIMs:

The elim.gpfshost ELIM monitors IBM Spectrum Scale counters at the LSF host level:

• Average MB In/Out per second
• Maximum MB In/Out per second
• Average file Reads/Writes per second
• Average file Opens/Closes/Directory Reads/Node Updates per second
• Health of the host

The elim.gpfsglobal ELIM monitors available IBM Spectrum Scale bandwidth at the LSF cluster level:

• MB available capacity In/Out

You can also view and graph these metrics in IBM Spectrum LSF RTM (LSF RTM). You can also define alerts.

Example usage:

• Check that the file system is healthy before dispatching a job:

  bsub -q normal -R"rusage[gstatus=ok]" ./myapplication myapplication_options

• Reserve 100 kilobytes of inbound bandwidth at the cluster level for 20 minutes:

  bsub -q normal -R"rusage[gtotalin=100:duration=20]" ./myapplication myapplication_options
