I would like to know if somebody have used the MPICH implementation with the Intel's Fortran 90 compiler for Linux or the Lahey's Fortran 90 for Windows.

I have a problem using both compilers under a Fortran 90 source code. The compiler does not recognize the mpi module or library.

Thanks in advance.

You probably want to test the MPICH installation by compiling its test programs and running them with different "-np *". If this works, you can then start thinking of using MPI in your own code.

Thank you for the answer.

The first thing I tried, was to compile the examples that come with MPICH.

But the fortran 90 ones fail to compile with the cited compilers.

Before you install the MPICH, you may have to set some environments first. Such as:

setenv FC f90

setenv F90 f90

configure

good luck!

There is NO problem for Intel Compiler 8.0 + MPICH + Linux. I have tried it.
