[MPICH] MPI Program in C++ Compilation problem

[Rajeev Thakur]

It's probably because the NFS on your machine is very slow. mpicc and mpiCC
are just simple scripts that call the real C and C++ compilers. If your
MPICH installation or code is on a slow NFS volume, it will take time to
compile.  

Also, 1.2.5 is a very old version of MPICH. You should use MPICH2 instead.
