Example of Script for PBS †
#!/bin/bash
#PBS -q QUEUE CLASS
#PBS -l mppwidth=32
#PBS -l mppdepth=1
cd $PBS_O_WORKDIR
aprun -n 32 -d 1 -N 8 ./a.out
- mppwidth=number of process
- mppdepth=number of thread <-- when mpi program, number of thread = 1.
- $PBS_O_WORKDIR <-- work direcotry
Useful Command †
| Command | Description |
| qsub <PBS script> | submit a job to a PBS batch system |
| nqstat | confirm the state of job |
| qdel <PBS script> | abort your job |
