EGO_DEFINE_NCPUS

Syntax

EGO_DEFINE_NCPUS=procs | cores | threads

Description

If defined, enables an administrator to define a value other than the number of cores available. Follow one of the three equations below for an accurate value.

  • EGO_DEFINE_NCPUS=procs-ncpus=number of processors

  • EGO_DEFINE_NCPUS=cores-ncpus=number of processors x number of cores

  • EGO_DEFINE_NCPUS=threads-ncpus=number of processors x number of cores x number of threads.

Note:

When PARALLEL_SCHED_BY_SLOT=Y in lsb.params, the resource requirement string keyword ncpus refers to the number of slots instead of the number of CPUs, however lshosts output will continue to show ncpus as defined by EGO_DEFINE_NCPUS in lsf.conf.

Default

EGO_DEFINE_NCPUS=cores
