Help with Purdue Tasks

• Connecting to the supercomputer (Windows):
  1. Download an ssh client - Click here for PuTTY
  2. Download an X client - Click here to download Cygwin
  3. (Optional) Forward X11 packets in the ssh client, and start X client, if using X applications
  4. (Optional) Upload files to server carter.rcac.purdue.edu using WinSCP - download here
  5. Connect to carter.rcac.purdue.edu with the ssh client using your Purdue credentials
  6. Read the Carter new user's guide -- click here
  7. Setup your account to automatically load necessary modules and environment variables with cd $HOME; ln -s ~pbermel/.profile; source ~/.profile.
  8. • FOR TEST JOBS: run meep with meep-mpi or meep-mpi my.ctl
     • FOR BIGGER, INTERACTIVE JOBS: run everything using the interactive version of qsub. For example, try echo $DISPLAY; qsub -I -q pbermel -l walltime=1:00:00 -l ncpus=16 to run for 1 hour on 16 cpu cores. Also use export DISPLAY=[earlier output] for running graphical programs (e.g., MATLAB).
     • FOR BIGGER, NONINTERACTIVE JOBS: run meep with the queueing system. First create a ctl file, then type, e.g., ~pbermel/meepctlq my.ctl $PWD/targetdir 48 1:30 to run my.ctl for an hour and 30 minutes on 48 cores, with output in targetdir. Check your job status in the queue via qstat -u `whoami`. If it's empty, your job is done. :-)
