LSF_GPU_AUTOCONFIG

Syntax

LSF_GPU_AUTOCONFIG=Y|N

Description

LSF_GPU_AUTOCONFIG controls whether LSF enables use of GPU resources automatically.

If set to Y, LSF automatically configures built-in GPU resources and automatically detects GPUs.

If set to N, manual configuration of GPU resources is required to use GPU features in LSF.

Whether LSF_GPU_AUTOCONFIG is set to Y or N, LSF will always collect GPU metrics from hosts.

The lsload -l command does not show GPU metrics. GPU metrics can be viewed using the lsload -gpu command, lsload -gpuload command, and lshosts -gpu command.

In addition, if LSF_GPU_RESOURCE_IGNORE is set to Y and LSB_GPU_NEW_SYNTAX is set to Y or extend, all built-in GPU resources (gpu_<num>n) are completely removed from the management host LIM, except for the following resources: ngpus, ngpus_physical, gpu_driver, and gpu_maxfactor. LSF uses a different method for the management host LIM and server host LIMs to collect GPU information. This improves LSF response time because there are fewer LSF resource metrics to configure and collect. Do not set LSF_GPU_RESOURCE_IGNORE=Y if you are using LSF RTM.

Note: On LSF systems using RHEL, version 7 or higher is required to support LSF_GPU_AUTOCONFIG.

Default

Y
