Viewing host architecture 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)
hostB ALPHA DEC3000 10.0 1 94M 168M Yes (alpha 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 608 for instructions on measures to
take.
When automatic detection of host type or model fails, the type or model is set to
DEFAULT. LSF will work on the host. A DEFAULT model may be inefficient because of
incorrect CPU factors. A
DEFAULT type may cause binary incompatibility because a job
from a
DEFAULT host type can be migrated to another DEFAULT host type.
Viewing host history
Run badmin hhist to view the history of a host such as when it is opened or closed.
For example:
% badmin hhist hostB
Wed Nov 20 14:41:58: Host <hostB> closed by administrator
<lsf>.
Wed Nov 20 15:23:39: Host <hostB> opened by administrator
<lsf>.
Viewing host model and type information
Run lsinfo -m to display information about host models that exist in the cluster:
