[mvapich-discuss] [EXTERNAL] Running LQCD chroma with MVAPICH2 encountered errors

[Ran Du]

Dear Balint,

        Thanks a lot for your reply.

        My colleague, Yujiang, did the Chroma test, and I am cc'ing him to
answer your questions about the test details.

        And I agree with your advice about issue reproduction, I will help
Yujiang, my colleague to reproduce the issue and post more detailed logs
here.

Kind regards,
Ran
