RTM reports job Mem Request, Mem Reserved in wrong unit

Troubleshooting


Problem

RTM reports job Mem Request, Mem Reserved in wrong unit. GB becomes MB, MB becomes KB.

Symptom

The command bjobs output shows Requested Resources <rusage[mem=400.00]>, which is in MB.

RTM job details show Mem Reserved = 400K

Resolving The Problem

There are two options:

1) apply Fix Pack 1 (rtm-10.1-build413549), preferred

The readme file lists the Fixes. For this issue, it says:

"Fix for the request/reserve memory when LSF_UNIT_FOR_LIMITS is not set in the LSF cluster."

You can also install the latest Fix Pack available from Fix Central, since FP is cumulative.

Or

2) quick fix

Add in lsf.conf

LSF_UNIT_FOR_LIMITS=MB

Then on LSF management node, run

lsadmin reconfig
