    9 The logger is started with `mpiexec` and subsequently starts the application to monitor. It will create a directory (default: `.memlog` in the `PBS_O_WORKDIR`, => `wrkdir`, option `-w`) and by default each task will create its own logfile in that directory. The logger checks now each time step (=> `delay`, option `-d`) for the following keys in the status file of each process (`/proc/<id>/status`):
    10   * `VmExe`
    11   * `VmSt`
    12   * `VmData`
    13   * `VmSize`
    14   * `VmLck`
    15   * `VmLib`
    16   * `VmRSS`
