More details from TSCC on compiling MPI

• Use the command

  qsub -I -l nodes=1:ppn=2 -l walltime=00:15:00 
  

  to start an interactive job on a single node with 2 cores for at most 15 minutes.

  Once you run it, it will wait until a node is available, and then it will create an SSH session to that node. Your job will last until you exit that SSH session.

• Then run a pthread program as a regular Linux job:

   binaryname 

  You may supply the number of pthreads as an argument so your program may create a given number of threads.

  Notes:

  • The interactive mode is the best for compiling code and debugging your program in a small setting. To report the execution time of your program, it is better to use the batch mode and the system can allocate more dedicated resources.
  • Remember to exit so that you don't waste a bunch of time doing nothing.

Make sure your code does not wait for an input from a user keyboard!

• The head part of this script file should contain information on the number of machines and cores to be be requested. You always use "hotel" queue to submit your job. More details on how to specify the head part
• To start a Pthread binary job after the resource specification, your script can include the two lines in the following format:

  cd ~/path-to-program
  binaryname 
  

• Command

  qsub job-script-file 

  will submit your job to the scheduler and assign it a job number. Be careful when you are submitting multiple jobs with the same output file names since they may get overwritten by subsequent or concurrent jobs.

• qstat -a and showq -u $USER are useful for examining the current state of your jobs. In qstat, Q means queued, R means running, and C means complete. showq will give you slightly more detailed information about your jobs.

• You may delete a job with "qdel jobnumber" where jobnumber was assigned by qsub.
