Hello all,
I'm running a global circulation routine on mitgcm on 32 processor and am looking to see if I can speed up the runtime. I had an IT person help and she sent me part of the profile (below). Most of the time seems to go into the routine "config_summary", which appears to just be IO. Is there any way I can reduce the number of times this routine is called? Does this have anything to do with the generation of STDOUT files?
Thanks for your help.
David
