Dear All
I want to run gromacs in parallel on cluster.for this I follow below steps:
1-I connect to a node with ssh comand,fro example: ssh compute-o-1
2-cd scratch
3-grompp -f md.mdp -c input.gro -o output.tpr -p
topol.top -n index.ndx
4- nohup mpirun -np 8 mdrun -deffnm output &
The result is running mdrun on one node(compute-0-1) (on its 4 CPUs)
Besides when I used the following command I get an executeable Error:
mpirun -np 8 mdrun_mpi -deffnm output &
The Error is related to mdrun_mpi
I think is related to my cluster,because both of above commands work in my
laptop
Please let me know how can I run mdrun on all of CPUs of my cluster.
Thanks in advance
Mohsen
