Platform LSF Administration Guide Version 6.2

Viewing Host Information

Administering Platform LSF

LOAD THRESHOLD USED FOR SCHEDULING:

r15s r1m r15m ut pg io ls it tmp swp mem

loadSched - - - - - - - - - - -

loadStop - - - - - - - - - - -

THRESHOLD AND LOAD USED FOR EXCEPTIONS:

JOB_EXIT_RATE

Threshold 4.00

Load 0.00

Use bhosts -x to see hosts whose job exit rate has exceeded the threshold for longer

than JOB_EXIT_RATE_DURATION, and are still high. By default, these hosts will be

closed the next time LSF checks host exceptions and invokes

eadmin.

If no hosts exceed the job exit rate,

bhosts -x displays:

There is no exceptional host found

Viewing dynamic host information

Use lshosts to display information on dynamically added hosts.

An LSF cluster may consist of static and dynamic hosts. The

lshosts command

displays configuration information about hosts. All these parameters are defined by the

LSF administrator in the LSF configuration files, or determined by the LIM directly

from the system.

Host types represent binary compatible hosts; all hosts of the same type can run the

same executable. Host models give the relative CPU performance of different

processors. Server represents the type of host in the cluster. “Yes” is displayed for LSF

servers, “No” is displayed for LSF clients, and “Dyn” is displayed for dynamic hosts. For

example:

lshosts

HOST_NAME type model cpuf ncpus maxmem maxswp server RESOURCES

hostA SOL64 Ultra60F 23.5 1 64M 112M Yes ()

hostB LINUX86 Opteron8 60.0 1 94M 168M Dyn ()

In the above example, hostA is a static host while hostB is a dynamic host.
