If the program contains MPI calls and MPICH is installed on the machine (true for
all Linux CTC machines with interactive access), one may type
> gcc parhello.c -lmpich -o parhello
or
> ifort parhello.f -lmpich -o parhello
This is sufficient because the mpi.h and mpif.h header files are in /usr/local/include
which is on your default include path. Similarly, the default library path includes
/usr/local/lib, where libmpich.a lives.
