Multi-threaded MPI communication

[mshiryaev]

Hello,

I wonder if multiple endpoints feature from Intel MPI 2019 can be beneficial for SNAP. As far as I understand SNAP has mode in which multiple OpenMP threads can communicate over MPI in parallel.

You can find more information about multiple endpoints here:

Still have this noted as question for investigation, but closing the ticket unless (until) further feedback is needed. Thanks.
