[gmx-users] MPI gromacs usage

[Diane Fournier]

Hi gromacs users
 
I've already used gromacs single-processor version and I want to use the parallel version of gromacs on a SGI Altix 2700 with 32 processors. I'm wondering how to proceed, because this does not seem to be explained properly anywhere. Do I have to give special instructions in grompp to split the simulation on several processors, or can I use the same .tpr file I'm using with the single-processor version of mdrun ?
 
Thank you
