HpcQueryGraphManager.exe is missing on compute nodes when running LinqToHpc jobs RRS feed

  • Question

  • Hi,

    We just installed the LinqToHpc beta, and started running the example code.

    When submitting the DupPic2 job, we found following error msg on one compute node via Hpc job manager.

    'HpcQueryGraphManager.exe' is not recognized as an internal or external command,
    operable program or batch file.

    We're sure that 'HpcQueryGraphManager.exe' is installed in HPC R2 bin directory in the head node, but not in that directory in compute nodes. Is there some component or service of LinqToHpc we forget to install?

    Thank you,

    Hui

  • Hello Arijit,

    Our system administrator has installed the LinqToHpc in compute nodes as you pointed out.

    The sample program run successfully without problem.

    Many thanks!

  • Hello Hui,

    HpcQueryGraphManager.exe is installed as part of compute node installation of LinqToHpc. A non-default installation directory may not be automatically put in the path. Please make sure that the installation directory is in the path (set path). If the default installation directory is chosen which is usually C:\Program Files\Microsoft HPC Pack 2008 R2\Bin\ then it will be in the path and nothing more needs to be done.

    How were the compute nodes installed?  If you are using LinqToHpcSetup.exe make sure you use the -computenode option as in "LinqToHpcSetup.exe -computenode:<Headnode Name>" or if you are using DISC_x64.msi use ADDLOCAL=Computenode option as in "DISC_x64.msi ADDLOCAL=Computenode"

    After the installation please review Control Panel -> Programs -> Programs and Features to make sure LinqToHpc is really installed.

    Please do post back if this doesn't solve the issue.

    Thanks, Arijit
