Examples of running UCVM Query on compute nodes on Discovery

allocation interactive nodes

Information To Prepare:

  • scalloc - command that will reserve a dedicated worker compute node for your program.
    • Using dedicated worker nodes should let your program run faster than shared headnode
  • Number of tasks - typically 1 unless running MPI codes
  • Expected max duration of program : Format HH:MM:SS
    • Longer runtimes can
    • HPC systems typically have max runtime (e.g. 24:00:00 or 48:00:00).
    • Must make arrangements with HPC system operates for longer runtimes
  • allocation account - who's allocation will be charged for computing time
    • CARC offers "no-cost" allocations to University researchers that request them
    • Allocation will also include dedicated disk storage on CARC /project filesystem (e.g. /project/maechlin_162 /project/scec_608)
  • Example command for running program on discovery:
    • %salloc --ntasks=1 --time=1:00:00 --account=scec_608

Example profile query

%ucvm_query -f /project/scec_608/<username>/ucvm_bin/conf/ucvm.conf -m cvmsi < rpv.in > rpv_cvmsi.out

  • ucvm_query -f /project/maechlin_162/ucvm_bin/conf/ucvm.conf -m cvmsi < rpv.in > rpv_cvmsi.out

slurm batch script

  • %cat ucvm_query.job
  • %sbatch ucvm_query.job
  • %squeue -u maechlin
  • %cat rpv_cvmsi.out
