Hi, John.
I recognize that build string as an old Cray release.  FWIW, I’m guessing that HZ==100 on that system.  I suggest that reach back to Cray support with questions.  Also inquire about the latest patch set for that release.

If you have the opportunity, I suggest that you try this code on system capable of running the latest 2.9.0 release.  There have been lots of client performance enhancements between ~2.5.2 from Cray and the new 2.9.0 release.  I’d be interested in what the new code improves.

Thanks,
-Cory
