LSF Version 7.3 - Administering Platform LSF

Viewing Host Information
64 Administering Platform LSF
View host load by host
The lsload command reports the current status and load levels of hosts in a cluster.
The
lshosts -l command shows the load thresholds.
The
lsmon command provides a dynamic display of the load information. The LSF
administrator can find unavailable or overloaded hosts with these tools.
1 Run lsload to see load levels for each host:
lsload
HOST_NAME status r15s r1m r15m ut pg ls it tmp swp mem
hostD ok 1.3 1.2 0.9 92% 0.0 2 20 5M 148M 88M
hostB -ok 0.1 0.3 0.7 0% 0.0 1 67 45M 25M 34M
hostA busy 8.0 *7.0 4.9 84% 4.6 6 17 1M 81M 27M
The first line lists the load index names, and each following line gives the load
levels for one host.
Viewing host architecture (type and model) information
An LSF cluster may consist of hosts of differing architectures and speeds. 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. For example:
lshosts
HOST_NAME type model cpuf ncpus maxmem maxswp server RESOURCES
hostD SUNSOL SunSparc 6.0 1 64M 112M Yes (solaris cserver)
hostM RS6K IBM350 7.0 1 64M 124M Yes (cserver aix)
hostC SGI6 R10K 14.0 16 1024M 1896M Yes (irix cserver)
hostA HPPA HP715 6.0 1 98M 200M Yes (hpux fserver)
In the above example, the host type SUNSOL represents Sun SPARC systems
running Solaris, and
SGI6 represents an SGI server running IRIX 6. The lshosts
command also displays the resources available on each host.
type The host CPU architecture. Hosts that can run the same binary programs should
have the same type.
An
UNKNOWN type or model indicates the host is down, or LIM on the host is down.
See UNKNOWN host type or model on page 709 for instructions on measures to
take.
When automatic detection of host type or model fails (the host type configured in
lsf.shared cannot be found), the type or model is set to DEFAULT. LSF will work
on the host, but a
DEFAULT model may be inefficient because of incorrect CPU
factors. A
DEFAULT type may also cause binary incompatibility because a job from
