I have a soft written in Fortran and usion MPICH distribution. I need to compile it using pgf90, ( presence of dynamic fortran allocation). Options ‘-i4 -r8’ are necessary to the compilation source.
But I try to use MPICH 1 distribution, so I guess that I need the same Fortran option.
If I’m not wrong, MPICH 1 seems to be written in C (the main part of the source). So I need to have equivalent option (which one?) for pgcc, no?
I have the same question for a compilation of MPICH 1 using ‘-i8’ Fortran option…? ( equivalent option of the C PGI compiler… ?)
thank for your help
