Hi,
I am trying to run lammps on 6-core cpu and 1 gpu system as:
3 mpi ranks x 2 OMP threads per rank + 1 gpu
kind of as done in this mail: http://lammps.sandia.gov/threads/msg58668.html
I compiled with yes-gpu and yes-user-omp
lmp_mpi -h does show various omp suffixed styles.
But when i run, either as:
lmp_mpi -sf hybrid gpu omp -pk gpu 1 -pk omp 2 -in input.in
or as
package gpu 1
package omp 2
in input file i get following warning:
WARNING: OpenMP support not enabled during compilation; using 1 thread only
why is that?
OMP_NUM_THREADS variable is also set to 2
