Dear Gromacs Users,
I have two questions about the multi-level parallelism of Gromacs.
1. Is this feature is only supported by Gromacs 4.6? Or we can get it
in 4.5.3 also?
2. In Gromacs 4.5.3, I have used OMP_NUM_THREADS=12 mpirun -np 16
mdrun_mpi -s imd.tpr command to run 16 gromacs processes each with 12
In the log file, I can see
nodeid: 0 nnodes: 16
Its clear that 16 nodes are being used in work load distribution. But
its not clear whether 12 thread is being used in each of those
processes /nodes because there is no mention about the number of
Does anyone know about this?
