Subject: [mvapich-discuss] Support for non-blocking collectives with    GPUDirect aSync feature

Hi,

as presented at GTC 2017 in the talk "MVAPICH2-GDR: Pushing the Frontier
of HPC and Deep Learning", there is initial support for the GPUDirect
aSync (GDS) feature in MVAPICH2-GDR. The slides show how to call
MPI_Isend, and present results for Send and Recv.

Is this feature already available for non-blocking collectives like
MPI_Ibcast?

Best Regards

Marius
