Error Loading libmpifort.so.12

Hello,

I am trying to run my executable (PDES Simulator - ROSS) on a cluster and I add the module mpich/ge/gcc/64/3.2rc2 for mpi support.

But I got "while loading shared libraries: libmpifort.so.12: cannot open shared object file: No such file or directory" error.

It looks like I need Fortran support but I do not see any Fortran library on my $PATH and "which libmpifort.so.12" gives me no such library message.

Which module should I add for libmpifort.so.12 ?

Thank you very much and sorry for the long and possibly unrelated details.

Sincerely,

Ali.
