IBM Spectrum LSF 10.1 Fix 521095 Readme File

Abstract

P103007. This fix maintains a consistent order for the GPU ID sequence among the job's tasks.

Description

Readme documentation for IBM Spectrum LSF 10.1 Fix 521095 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issue:

When the task number is larger than the GPU number for GPU affinity jobs, the sequence of the GPU ID column might be out of order.

For example:

        If the following GPU affinity job is dispatched to a candidate host that has two sockets and each socket has 4 GPUs:

               bsub -n 16 -R "affinity[core(1)]" -gpu "num=8:mode=exclusive_process:mps=yes" sleep 10000

        LSF cannot keep a consistent order for the GPU ID sequence among the job's tasks.
