[mvapich-discuss] DAPL_PROVIDER

[Abhinav Vishnu]

Hi Matthias,

Thanks for your interest in MVAPICH and reporting this issue.

At this point, MVAPICH assumes the presence of a uniform DAPL_PROVIDER
for all participating processes. To solve your problem, we are working on
a solution that would allow the presence of different DAPL_PROVIDER values
for different processes. We will keep the group posted on this front.

Thanks a lot again.

regards,
