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

[Subramoni, Hari]

Hi, Liwei.

This is different from the issue that was reported on mvapich-discuss a few days ago. We are still trying to investigate whether this combination is expected to work. We will get back to you soon with more details.

Thx,
Hari.

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

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
