[gmx-users] problems with MPI

[giorgio colombo]

Dear All,

I just installed gromacs3.0.5 on a pc with two AMD Athlon processors.
gromacs compiled fine, but when I try to run it with the command:

mpirun -np 2 /home/gmx3.0/i686-pc-linux-gnu/bin/mdrun -s topol.tpr

nothing happens, I just get the shell-prompt back.
I tried several times to recompile it and reinstall mpi, but I always
get the same result.

the tpr file was correctly prepared for runs on two processor with
grompp.

Thanks for your help
