One of our users has asked a question regarding the PGI MPI setup:
Anyway, I found the latency and bandwith of the GNU MPI library are
both 10 times better than the PGI MPI library.
Can you confirm if either PGI and GNU are installed to perform TCP/IP
between cores or do they both use local memory references.
Can someone tell me which is the case for PGI?
It’s just a default installation - no extra configuration.
