Hi Hesam,
According to an earlier work of our ALCF Catalyst, using a combination of -O3 and -qhot was improving the performance in previous generations of BG/Q compilers so further testing could be helpful.
Best.

Dear Neks
I was wondering if anyone here could give me the recommended set of
compilers and flags for running nek on BG/Q so that I could modify
makenek. I guess the experienced users of Mira could be of great help.
Regards,
Hesam
