Running PWscf (Example)
Download QE benchmarks
| Code Block |
|---|
git clone https://github.com/QEF/benchmarks.git |
Practice with one of the small benchmarks called “AUSURF112” (not part of the online task, just to practice)
| Code Block |
|---|
cd benchmarks/AUSURF112 mpirun -np <NPROC> <MPI FLAGS> pw.x -inp ausurf.in |
...
We will look for the final wallclock time (WALL).
