Error while executing LINQToHPC DupPic2 Sample RRS feed

    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.

    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.
