LSF Version 7.3 - Platform LSF Configuration Reference

The operating system can assign other processes to run on the same CPU; however, if

utilization of the bound CPU is lower than utilization of the unbound CPUs.

Related parameters

To improve scheduling and dispatch performance of all LSF daemons, you should use

LSF_DAEMONS_CPUS together with EGO_DAEMONS_CPUS (in ego.conf or

lsf.conf), which controls LIM CPU allocation, and MBD_QUERY_CPUS, which binds

mbactchd query processes to specific CPUs so that higher priority daemon processes can run

more efficiently. To get best performance, CPU allocation for all four daemons should be

assigned their own CPUs. For example, on a 4 CPU SMP host, the following configuration

gives the best performance:

EGO_DAEMONS_CPUS=0 LSF_DAEMONS_CPUS=1:2 MBD_QUERY_CPUS=3

Examples

If you specify

LSF_DAEMONS_CPUS="1:2"

the mbatchd processes run only on CPU number 1 on the master host, and mbschd run on

only on CPU number 2.

If you specify

LSF_DAEMONS_CPUS="1 2:1 2"

both mbatchd and mbschd run CPU 1 and CPU 2.

Important

You can specify CPU affinity only for master hosts that use one of the following operating

systems:

•

Linux 2.6 or higher

•

Solaris 8 or higher

EGO parameter

LSF_DAEMONS_CPUS=lim_cpu_list: run the EGO LIM daemon on the specified CPUs.
