From GridLAB-D Wiki
The processor affinity API uses a global map of the processor affinities for all instances of GridLAB-D running on a machine. To display the global process map, use the --pstatus command line option.
host% gridlabd --randtest & gridlabd --pstatus PROC PID STATE CLOCK COMMAND 0 16807 Running INIT /usr/lib/gridlabd/gridlabd.bin --pstatus 1 16808 Running INIT /usr/lib/gridlabd/gridlabd.bin --randtest
This global map can become corrupted in the event of the failure of an instance of GridLAB-D that leaves a zombie entry in the process map. In such circumstances the --clearmap command option can be used to purge the map. A process can be killed and removed from the list using the --pkill command option.
