Dear all,

I am new in Gromacs 4.0.7 before this I was using the GROMACS 3.3.3.....
I have some doubt in the grompp commands when i want to run in parallel

In Gromacs 3, I just use:

grompp_mpi -v -f _ _ _ -np 4
then,

mdrun_mpi -v -f -deffnm -np 4

but in Gromacs 4, I cant use 4 nodes in grompp in order to prepare tpr file for 
4 nodes to be used in mdrun_mpi....
there is no option -np in grompp and grompp_mpi

Is it there is change in the command?

or is due to other problems?

THANKS.....


You posted this message already, and received two replies, one of which pointed you to a web link with a very clear solution:

And you can always check the options of every command with "-h", i.e.:

grompp -h

should give you some very obvious information.
