cuda + mpi RRS feed

  • Question

  • Some people use cuda+mpi on HPC Server 2008 ?

    I have 4 PC OS: Windows HPC Server 2008(x64)
    Hardware : Tesla C1060 +Quadro NVS 295
    compile tool : Visual Studio 2008 C++ with MSMPI library .
    I run example by nvidia GPU Computing SDK (Device Query)

    When only run Device Query , I get some message....

    There are 2 devices supporting CUDA ...
    Device 0 : "Tesla C1060 ".....
    Device 1 : "Quadro NVS 295"....

    But when I mpi+cuda by HPC Cluster Manager , I get message...

    Hi, I am CPU 0
    "There is no device supporting CUDA."
    "Device 0: "Device Emulation (CPU)"

    What are your views ?
    By the way...my Tesla C1060 driver software is Vista x64 because I could not fount the driver for Windows HPC Server 2008.

  • Hi.

    There is a WDM driver from NVidia for their Tesla devices available, it works with CUDA on HPC Server 2008 (including R2). If you are not using this driver, you have to have an interactive session open on the same compute node with the same user name as the job is running on (see http://resourcekit.windowshpc.net/MORE_INFO/33b-GPU%20Computing%20in%20Windows%20HPC%20Server%202008.html for details on this).

     

    Kind regards,
