  • Everyone with access to a terminal (via Macintosh, Linux, or PuTTY for Windows) is a participant.
    • People without access are observers. Feel free to look on with a participant or get terminal access and become one.

    • Only the local leader may communicate with the global leader

    • Log into cluster.earlham.edu with your assigned username and password.

      3. cd acca
      4. cd stats
      5. perl stat.pl -t al-salam.sh --scheduler pbs --cl 'mpirun -np $processes ~/acca/area-under-curve/area-mpi -s 100000000000' --processes Your Number --ppn 8 --proxy-output
  • You should receive a message that your job has been submitted. It will take about five minutes to run, depending on the number of processes you used.
