[mvapich-discuss] MVAPICH on POWER9 + Volta

[Kate Clark]

Hi DK,

Thanks for the response, and it is great to hear that this working.

- Will the OpenPOWER / CUDA 9.0 binary that is available work on Summit as is (when used in conjunction with CUDA 9.0) or is a new build required?

- Since CUDA 9.2 is available on Summit, are you going to provide a pre-built binary for CUDA 9.2 on Summit?

Thank you,

Kate.

    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.
