        This update fixes an issue that can occur when a task with multiple dependencies is added to a submitted job. The newly added task fails with the error “Invalid task dependency: no basic or parametric task named '[TaskName]' could be found in the job. A task may only depend on another basic or parametric task. Please check your spelling and try again.”

        An HPC Pack 2012 R2 cluster
      • This update needs to be run only on head nodes.

        It is recommended to stop all active jobs and back up the head node (or head nodes) and HPC databases before installing/uninstalling the update.

        Applying the update

        To apply the update, run the KB2956330.exe on the head node by using an administrator account. A system reboot may be required after the installation.
        Note: If you have high availability head nodes, run the fix on the active head node, move the node to passive, and after failover occurs run the fix on the new active head node. Do this for all head nodes in the cluster.

        Uninstalling the update

        To uninstall the update, in Control Panel, click Programs select View installed updates, and double-click 'HotFix KB2956330 for Microsoft HPC Pack 2012 R2'.
        Note: If you have high availability head nodes, uninstall the update on a passive head node, move the node to active, and then repeat uninstallation on the new passive head node. Do this for all head nodes in the cluster.
