    Hi,

    I have an application that runs across 2-3 nodes that write data to a local c:\scratch on each node.

    I would like to have this directory cleaned out on each node at the end of the job before the next job starts, even if the job is cancelled.

    Is their a "Prologue" functionality in CCS, or what is the recommended way to do this.

    Thanks,

    Cham Dorr

    Cham,

     

    Unfortunately there is no prologue, but you can add a clean up task in your job that depends on your write data.

    I suggest you to write a little batch file that you can mpiexec like this :

     

    mpiexec -hosts %CCP_NODES: 4= 1% cmd /c cleanup.cmd

     

    this is to execute on 4 core servers only one cleanup.cmd batch file.

     

    If the job failed or is cancelled, this task may be executed. I suggest you eventually to do a cleanup before starting your job too.

    So in your job you ay have 3 tasks :

    cleanup

    compute

    cleanup
