If you compile by yourself MPICH2 locally I suggest to use CC=icc and FC=ifort, do not mix compilers. Most of the time the mixing is harmless but I would not bet money that it is _always_ harmless. Moreover MPICH2 is old, try Open MPI instead (http://www.open-mpi.org/)

Yes, it is called serial compilation :-)

./configure --enable-openmp --disable-parallel

Regards,
Filippo
