[Nek5000-users] Compilation flags on BG/Q

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

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.
Aleks

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
