I've tried to recompile gromacs, this time i tried to enable mpi so tha t i can run in parallel. I did what you advised in my last post. I've checked on the gromacs homepage, and tried to find instructions for that. Eventually what i did was.<br>
In the gromacs directory i typed:<br>make distclean<br><br>and then i wrote the command line described below.<br>i says it can't compile and link mpi code with cc.<br>lam-mpi is already installed, i would really appreciate some help with this problem.<br>
