Change default actions.
Description:
Change the default maximum number of processes (-P) to use all processes
instead of just 1 (old default). Someone most likely wants to test
the I/O performance with all processes involved.
Also starts performance measurement with maximum number of processes
and decrement it with each loop. If the performance measurement
needs to restart, it can run with fewer processes if those loops
have completed.
Platforms tested:
modi4 and eirene.
