    Baris,
    Still strugling to get this case running.
    I assume the materials has not been uploaded yet.

    My case resolves already after 7 itterations. Not sure what I need to change.

    WARNING: Linux kernel CMA support was requested via the
    btl_vader_single_copy_mechanism MCA variable, but CMA support is
    not available due to restrictive ptrace settings.

    The vader shared memory BTL will fall back on another single-copy
    mechanism if one is available. This may result in lower performance.

    mpirun detected that one or more processes exited with non-zero status, thus causing
    the job to be terminated. The first process to do so was:
