Introduction
Cpmd is provided so jobs can be run in the mpi queue on sharcnet clusters.
Usage on Graham
Version Selection
module load cpmd/3.17.1
Job Submission
Graham uses Slurm scheduler, which is different from the sq command used on other Sharcnet clusters. For details about submitting jobs, see Running Jobs.
Example script for a parallel job
#!/bin/bash #SBATCH --nodes=1 --ntasks-per-node=32 # 1 node with 32 cpus, MPI job #SBATCH --mem-per-cpu=2G # memory, should be less than 4G #SBATCH --time=00-01:00 # time (DD-HH:MM) #SBATCH --output=%J.log # output .log file module load cpmd/3.17.1 srun cpmd-mpi.x inputfile.inp # srun command
You can modify the script to fit your job's requirements for compute resources.
Usage on Legacy systems
Version Selection
module load cpmd/3.17.1
Job Submission
sqsub -r 1h -q mpi -n 16 -o ofile%J cpmd-mpi.x methan-fd-nosymm.inp
where 2 < -n ncpus < ncpusmax should be established by running scaling tests for ncpu= 2, 4, 8, 16 ...
Example Job
To run the std/wat32 example from cpmd-test.tar.gz do the following:
cp -a /opt/sharcnet/cpmd/3.17.1/test/CPMD-test/std /scratch/$USER/std/wat32 cd /scratch/$USER/std/wat32 module load cpmd/3.17.1 sqsub -r 1h -q mpi -n 16 --mpp=500M -o ofile%J cpmd-mpi.x inp-1
Warning: The femd example contains a bug that results in jobs crashing if run under cpmd/3.17.1 described in http://cpmd.org/track-issues/issues-tracker/10.
