There are three major configuration steps required to enable
the automatic CPU frequency selection feature of LSF:
Install benchmarking programs
Calculate coefficients data
Submit a job using an energy policy tag name
Installing and configuring benchmarking programs
You must install and run 7 benchmark programs (6 NPB and
1 STREAM) on all compute nodes that will calculate coefficients (or
make them available in a location accessible by all compute nodes).
Checking compute node performance
Before calculating coefficient data for each
compute node it is necessary to check that the performance of each
compute node in the cluster performs as predicted. This is done by
running the STREAM benchmarking program.
Calculating coefficient data
LSF provides an initialization script (initialize_eas
in $LSF_BINDIR) that calculates coefficients and must be run on all
compute nodes.
Setting a default CPU frequency
Compute nodes run in the nominal frequency by default.
When the node is idle or when it finishes running a job with an energy
policy, the compute node switches back to the nominal frequency.
