[mvapich-discuss] MVAPICH2 2.3rc2 XRC bug fix details

Tue May 1 13:08:35 EDT 2018

Hi Mvapich expert,

I am evaluating the latest MVAPICH2 2.3rc2 release. From the changelog, it
has a bug fix " Fix issue with XRC connection establishment". Can you
provide more details on this bug fix?

When I used MVAPICH2 2.3 rc1 on Mellanox ConnectX4 RoCE last week, I found
XRC will cause MPI to hang. Is the bug fix related to this issue?

Thanks,

Liwei
