Problem in runnig mpirun command
Posted: Fri Oct 06, 2023 5:00 am
After generating all 4 files i.e. POTCAR, POSCAR, INCAR, and KPOINT required for further calculations, i tried to run the command:
[pc@fedora ~]$ cd ~/Downloads/VASP/Calculation/GST/
[pc@fedora GST]$ mpirun -np2 vaspstd
But it's showing:
Open MPI has detected that a parameter given to a command line
option does not match the expected format:
Option: n
Param: vaspstd
This is frequently caused by omitting to provide the parameter
to an option that requires one. Please check the command line and try again.
I am not able for figure it out that what are the changes that required to make in which file or anything else can fix this problem?
