Error while executing LINQToHPC DupPic2 Sample RRS feed

  • Question

  • I have set up Windows HPC PACK 2008 R2 environment with 1 head (Windows Server 2008 R2 ) and 2 compute nodes (Windows Server 2008 R2 ) , and client (Windows 2003 Server) I can able to execute SOA samples from the client .

    But when I try to run LINQToHPC samples, DupPic2 , when it tries to check context.DscService.FileSetExists(inputFileSetName), it throws exception saying {"Failed to get fileset /user_DupPicImages from DSC service headnode. Cannot connect to headnode."} Source=Microsoft.Hpc.Dsc
      ErrorCode=290.

    I am unable to trouble shoot the issue .

    Note: On the client machine i separatly installed LINQToHPC client utils as it didn't get installed as part of Windows HPC client setup.

    when i debug the program HPCLinQContext object has ClientVersion = {3.2.3718.0} and ServerVersion = {3.2.3639.0}, I suspect some sort of version compatability.

  • Hi Aravindakumar,

    I think client and server version mismatch is most likely what's causing you the problems. And I think there are two things you can try here"

    1. go to C:\Program Files\Microsoft HPC Pack 2008 R2\Bin on your headnode, copy everything and paste into your client machine, the overwriting should get rid of any version mismatch.

    2.re-install L2H on your headnode, compute node, and client, using the same installation file.

     

    Hope this helps, and please let me know how things goes.

  • Hi Aravindakumar,

    Do you hve the DSC server setup? Can you check if you have the process "hpcdsc" running on your head node?

  • Thanks Michael for your reply.

    hpcdsc service is running on the head node.

        Also when i tries to run the DSC Node List command from client machine , I am getting error ,Please see details below

    >DSC NODE LIST /Service:headNodeInst

    Error: Failed to list nodes. Cannot connect to headNodeInst.

    But I can able to telnet to headNodeInst on port 6498

  • Hi Aravindakumar,

    What happens if you run DSC node list from the headnode? Do you get any response?

  • Thanks Michael, copying the bin folder, to client machine worked out...

    One thing i want to clarify...i copied the bin folder dlls to a 32 bit client machine and a 64 bit client machine...

    In both client machines DSC command prompt commands worked out...but  DupPic2 sample failed at context.DscService.FileSetExists(inputFileSetName)on 32 bit client machine saying unable to connect to head node but 64 bit client machine is fine.... Any thoughts why?

  • Hi Aravindakumar,

    32-bit DSC client is not supported, please stay with 64-bit client, thanks.
