Basic Unix
- Hands-on Linux Introduction
- How to submit parallel VASP jobs over 4 cores of keldysh:
$ module load vasp/5.4.4-intel-2023 $ mpirun -n 4 vasp_std
- How to submit parallel openmx jobs over 16 cores of keldysh:
$ module load openmx $ mpirun -np 16 openmx material.dat -nt 4 > material.std
Note that OpenMX has hybrid MPI/OpenMP parallelization, so nt specifies the number of threads in each process managed by MPI. If '-nt' is not specified, then the number of threads is set to 1, which corresponds to the flat MPI parallelization.
