Submitting and Managing Jobs

User Job Submission Parameters:

HPCC users are expected to specify resource usage and charging parameters. Specifically, when submitting a job to the resource manager users are expected to designate WC, Nodes, CC, JP, queue, and the charging account associated the run. These parameters are to be passed to the resource manager in the form of script comments as follows:
----------------------------------------------------------------------------
#PBS -l nodes=<number of nodes or list of nodes>:ppn=<number of processors to user per node>,walltime=<dd:hh:mm:ss>
#PBS -N <job name>
#PBS -o <job output file>
#PBS -e <job error file>
#PBS –A <job account to charge>
#PBS -q <queue to submit job to>
#PBS –p <job priority>
<command to be executed>
----------------------------------------------------------------------------
In such a case that the user does not specify these parameters a default set of parameters will be appointed to the job submitted to the resource manager by the user. The following are a list of charging parameters available in the IBM HPCC:
  • Available parameters for the line: #PBS -l nodes=<number of nodes or list of nodes>:ppn=<number of processors to user per node>,walltime=<dd:hh:mm:ss>
    • nodes=(1-28, ec1-ec24, or evc1-evc4)
    • ppn=(1-8)
    • walltime=(00:00:00:01 - 11:10:00:00)
  • Available parameters for the line: #PBS -q <queue to submit job to>
    • Queues available are:
      • batch: default batch with access to all priorities and an unlimited wall clock limit
  • Available parameters for the line: #PBS –p <job priority>
    • Priorities available are:
      • low: low priority queue charging factor of 0.75
      • normal: standard priority queue charging factor of 1.0
      • highpriority: higher priority queue charging factor of 1.25
      • deadline: highest priority queue charging factor of 1.5

Default Submission Parameters:

Default parameters that will be assigned to job submission scripts that are missing required parameter definitions are assigned as follows:
  • Default parameters for the line: #PBS -l nodes=<number of nodes or list of nodes>:ppn=<number of processors to user per node>,walltime=<dd:hh:mm:ss>
    • nodes=1
    • ppn=8
    • walltime=00:01:00:00
  • Default parameter for the line: #PBS -q <queue to submit job to>
    • #PBS -q batch
  • Available parameters for the line: #PBS –p <job priority>
    • #PBS -p normal
