model
Description
Host model
The name must be defined in the HostModel section of
lsf.shared. This determines
the CPU speed scaling factor applied in load and placement calculations.
Optionally, the
! keyword for the model or type column, indicates that the host model
or type is to be automatically detected by the LIM running on the host.
nd
Description
Number of local disks
This corresponds to the
ndisks static resource. On most host types, LSF automatically
determines the number of disks, and the nd parameter is ignored.
nd should only count local disks with file systems on them. Do not count either disks
used only for swapping or disks mounted with NFS.
Default
The number of disks determined by the LIM, or 1 if the LIM cannot determine this
RESOURCES
Description
The static Boolean resources available on this host
The resource names are strings defined in the Resource section of
lsf.shared. You
may list any number of resources, enclosed in parentheses and separated by blanks or
tabs. For example:
(fs frame hpux)
Optionally, you can specify an exclusive resource by prefixing the resource with an
exclamation mark (!). For example, resource
bigmem is defined in lsf.shared, and is
defined as an exclusive resource for
hostE:
Begin Host
HOSTNAME model type server r1m pg tmp RESOURCES RUNWINDOW
...
hostE ! ! 1 2.0 10 0 (linux !bigmem) ()
...
End Host
You must explicitly specify the exclusive resources in the resource requirements for the
job to select a host with an exclusive resource for a job. For example:
% bsub -R "bigmem" myjob
or
% bsub -R "defined(bigmem)" myjob
