Arkansas High Performace Computing Center [hpcwiki]

To start an interactive use the qsub command with the -I option:

razor-l1:pwolinsk:$ qsub -I 
qsub: waiting for job 1451274.sched to start
qsub: job 1451274.sched ready

PBS_NODEFILE=/var/spool/torque/aux/1451274.sched PBS_NUM_NODES=walltime=03 PBS_PPN=walltime=03:00:00 PBS_PPA=12
Currently Loaded Modulefiles:
  1) os/el6
compute1141:pwolinsk:$ 

This command starts an interactive job with default parameters:

• 1 core on 1 node on the tiny12core queue for 3 hours

To explicitly specify these options please use the following parameters to the qsub command.

razor-l1:pwolinsk:$ qsub -I -l walltime=2:01:00 -l nodes=1:ppn=2 -q student48core
qsub: waiting for job 1451283.sched to start
qsub: job 1451283.sched ready

PBS_NODEFILE=/var/spool/torque/aux/1451283.sched PBS_NUM_NODES=1 PBS_PPN=2 PBS_PPA=48

For information about the available queues on Razor and Trestles please see queues.

Interactive jobs end when you disconnect. If your job is done computing and is at a system prompt, please exit the compute node so it can be reused. If you have unreliable network access that doesn't last as long as an interactive job, see GNU Screen at Yale CRC.
