- Paths to commands:
- /usr/local/{bin,sbin} for PBS.
- /usr/local/maui/{bin,sbin} for Maui.
- Commands you'll probably use:
- qsub: Submit a job to a PBS queue.
- showq: Shows jobs Maui can schedule.
- qstat: Shows jobs that PBS advertises.
- canceljob: Cancels jobs in Maui.
- qhold: Holds a job from execution.
- Commands have man pages.
- To submit a job to PBS, you'll need to write a shell script wrapper around it and execute it with qsub on b0. There are commented option to PBS that qsub will interpret. Here's an example script:
#!/bin/sh #PBS -N primes_block #PBS -o /cluster/home/skylar/athena/src/primes4/out.txt #PBS -e /cluster/home/skylar/athena/src/primes4/err.txt #PBS -q batch #PBS -m abe
lamboot -v /cluster/home/skylar/athena/lam-bhost.def
mpirun C /cluster/home/skylar/athena/src/primes4/primes_block -n 1000000 -s 500
lamhalt
exit $!
-N gives the job name. -o tells PBS where to copy STDOUT to. -e tells PBS where to copy STDERR to. -q tells PBS which queue to submit the job to. -m abe tells PBS what mail options to use. abe enables all mail information.
- To submit that job, you might run something like this on b0:
qsub -l nodes=8,cput=0:30:0 ./primes_pbs.sh
This will request 8 nodes for a total of 30 minutes CPU time.
- For SMP nodes, use -l ppn=n, where n is the number of processors to request in a machine. For example, use 2 to request dual-processor nodes.
