Hi Lorenzo, My understanding is that you must have ISO_Fortran_binding support in your Fortran compiler in order to use the mpi_f08 capabilities of MPICH. Currently, GFortran (as of 8.2) does not support ISO_Fortran_binding natively. However, you may try downloading and installing ISO_Fortran_binding from: https://github.com/sourceryinstitute/iso_fortran_binding. Currently, the tests make use of C VLAs, so if you compile with a C compiler other than GCC the tests may fail to build. However, the runtime *should* (AFAIK) still work, as I don't believe we used VLAs or any other (breaking) GNU extensions in the source itself. If you install ISO_Fortran_binding onto your default system search path before configuring MPICH, then I think MPICH will find it and enable the f08 module. I have no idea what is wrong with TotalView. Good luck!

Hello,
After the mpich installation I have these two issues:
- I cannot use the module mpi_f08 in a Fortran program, only the old mpi module. The compilation error is:
Fatal Error: Can't open module file ?mpi_f08.mod? for reading at (1): No such file or directory compilation terminated.
- I cannot debug with Totalview. Totalview freezes when starting a debug session with "go" and a breakpoint, without error message. Maybe there was something wrong in my debug configuration options?
Attached are my c.txt and m.txt files.
Thanks for helping! Best, Lorenzo
