Dear CP2K users and developers,
I am a little confused about how to run cp2k with openmp or mpi+openmp.
1. ssmp with openmp in one node (not popt, sorry for the error in the
subject)
$ export OMP_NUMBER_THREADS=12
$ cp2k.popt test.in
or just
$ mpirun -np 12 cp2k.popt test.in
2. psmp with mpi+openmp in 8 nodes
$ mpirun -np 12 -machinefiles mpd.hosts cp2k.psmp test.in
If this cmd is correct, how do I make openmp work? export
OMP_NUMBER_THREADS before this cmd?
Thanks.
Zhengyi Zhang
