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
