 Priority:  minor       |   Milestone:          
Component:  SimFactory  |     Version:

 Submitting on Kraken with;

 sim --remote kraken create-submit maxwell_1proc --testsuite --procs 6
 --num-threads 6 --walltime 4:00:00

 leads to an error from aprun along the lines of -n cannot exceed -N
 (sorry, I deleted the error message). The idea was to get one MPI process
 with 6 threads. This same simfactory submission command works on Datura.
 The workaround is to use additionally --ppn-used=6.  Is there some
 documentation for what each of these command line options precisely does?
