Static Resources
Static resources are built-in resources that represent host information that does not
change over time, such as the maximum RAM available to user processes or the number
of processors in a machine. Most static resources are determined by the LIM at start-up
time, or when LSF detects hardware configuration changes.
Static resources can be used to select appropriate hosts for particular jobs based on
binary architecture, relative CPU speed, and system configuration.
The resources
ncpus, maxmem, maxswp, and maxtmp are not static on UNIX hosts
that support dynamic hardware reconfiguration.
Static resources reported by LIM
CPU factor (cpuf)
The CPU factor is the speed of the host’s CPU relative to other hosts in the cluster. If
one processor is twice the speed of another, its CPU factor should be twice as large. The
CPU factors are defined by the LSF administrator. For multiprocessor hosts, the CPU
factor is the speed of a single processor; LSF automatically scales the host CPU load to
account for additional processors.
Server
The server static resource is Boolean. It has the following values:
◆ 1 if the host is configured to run jobs from other hosts
◆ 0 if the host is an LSF client for submitting jobs to other hosts
