[Nek5000-users] changing the number of cores in conjunction with new restart

[nek5000-users at lists.mcs.anl.gov]

Hi Johan;

I used both PN_PN and PN_PN-2. I had the same experience with PN_PN-2;
however, PN_PN survived and ran very well. By any chance, I just wanted
to say thanks to Paul for developing this new restart features. It's
amazingly well preserving the field.

Best regards
Azad
