I think so too. It's a system-specific problem.
The Benchmark runs and finish with the following:
NODE (s) Real (s) (%)
Time:782.000782.000100.0
13:02
(Mnbf/s) (GFlops) (ns/day) (hour/ns)
Performance: 56.745
It could be system-specific. Could you try out dppc in tutor/gmxbench or
download gmxbench from gromacs' website (section Benchmark)?

Why don't you use Fedora's fftw & lam?
I have been using Fedora's fftw & openmpi with Gromacs without any
problems.
Do you have some other processes running on you
same problem as mpich2.

I don't think Python is to be blamed.
How about lam-mpi?

Pertinent information would include:
1. Gromacs version
2. MPI implementation you are using (OpenMPI, lam, etc.)
3. Hardware details
4. MPI host configuration
5. GROMACS command lines you're using

Otherwise, we're left to assume that you've simply done something wrong,
