LSF Version 7.3 - Administering Platform LSF

Common LSF Problems
710 Administering Platform LSF
incorrect CPU factors. A DEFAULT type may also cause binary incompatibility
because a job from a DEFAULT host type can be migrated to anotherDEFAULT
host type.
1 Run lshosts. If Model or Type are displayed as DEFAULT when you use
lshosts and automatic host model and type detection is enabled, you can leave
it as is or change it. For example:
lshosts
HOST_NAME type model cpuf ncpus maxmem maxswp server RESOURCES
hostA DEFAULT DEFAULT 1 2 256M 710M Yes ()
If model is DEFAULT, LSF will work correctly but the host will have a CPU
factor of 1, which may not make efficient use of the host model.
If type is DEFAULT, there may be binary incompatibility. For example, there are
2 hosts, one is Solaris, the other is HP. If both hosts are set to type DEFAULT, it
means jobs running on the Solaris host can be migrated to the HP host and
vice-versa.
Fixing DEFAULT matched host type or matched model
1 Run lim -t on the host whose type is DEFAULT:
lim -t
Host Type : LINUX86
Host Architecture : SUNWUltra2_200_sparcv9
Physical Processors : 2
Cores per Processor : 4
Threads per Core: : 2
Matched Type: DEFAULT
Matched Architecture: DEFAULT
Matched Model: DEFAULT
CPU Factor : 60.0
Note the value of Host Type and Host Architecture.

a In the
HostType section, enter a new host type. Use the host type name
detected with
lim -t. For example:
Begin HostType
TYPENAME
DEFAULT
CRAYJ
LINUX86
...
End HostType
