LSF_PE_NETWORK_NUM

Syntax

LSF_PE_NETWORK_NUM=num_networks

Description

For LSF IBM Parallel Environment (PE) integration. Specify a value between 0 and 8 to set the number of InfiniBand networks on the host. If the number is changed, run lsadmin reconfig and badmin mbdrestart to make the change take effect

LSF_PE_NETWORK_NUM must be defined with a non-zero value in lsf.conf for LSF to collect network information to run PE jobs.

Note: If LSF_PE_NETWORK_NUM is configured with a valid value, MAX_JOBID in lsb.params should not be configured with a value larger than 4194303 and MAX_JOB_ARRAY_SIZE in lsb.params should not be configured with a value larger than 1023. Otherwise, the jobID may not be represented correctly in PE and jobs do not run as expected.

Example

For example, hostA has two networks: 18338657685884897280 and 18338657685884897536. Each network has 256 windows. Set LSF_PE_NETWORK_NUM=2.

Maximum
