Power Testbed

Jobs for the power testbed can be submitted for a specific queue.

qsub -q R_powertestbed -l select=16:ncpus=128:mpiprocs=32 -l walltime=24:00:00 ./run.job.16N.mid_power.sh

Depending on the mode of operation the testbed either dynamically steers power consumption per socket of uses a given predefined power per socket level.

Irrespective of the type of execution, two types of files are generated and rsynced to

/lustre/hpe/ws10/logs/powersched: hdf5 raw output, containing 

• RETIRED_INSTRUCTIONS
• CPU_CLOCKS_UNHALTED
• RAPL_PKG_ENERGY

as well as a set of corresponding plots.
