[mvapich-discuss] MVAPICH on POWER9 + Volta

[Panda, Dhabaleswar]

Hi, 

Sorry for the delay in replying as nv_peer_mem modules were not available on Sierra compute nodes. Once these modules were made available a few days back, it has been verified that MVAPICH2-GDR with its GPU Direct RDMA feature works well on Sierra. 

No detailed performance comparison against Spectrum MPI has been carried out yet. 

Thanks, 

DK

Hi,

Does MVAPICH2-GDR support rdma transfers between GPU and NIC when running on IBM’s POWER9 platform, eg the Summit and Sierra systems at ORNL and LLNL?

Has there been a comparison against performance of Spectrum MPI?

Thank you,

Kate.
