P101493. This fix enables the LSF GPU feature to prevent jobs without GPU requirements from accessing GPU resources.

Description

Readme documentation for IBM Platform LSF 9.1.3 Fix 377982 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issue:

Jobs without GPU requirements have access to GPU resources.

This fix prevents jobs without GPU requirements from accessing GPU resources. If at least one of the LSF GPU resources (ngpus_shared, ngpus_excl_p and ngpus_excl_t) is configured, LSF configures the following for jobs without GPU requirements :

1. Sets CUDA_VISIBLE_DEVICES="" for the job.
2. If the GPU enforcement feature is enabled, LSF creates a devices cgroup for the job and sets the GPU denied list for this cgroup. The GPU denied list includes all GPU resources on the host.
