I have up till now used Intel Fortran under Windows and also Intel MPI on Intel CPUs. Has anybody experiences from moving to AMD CPUs from such an Intel-based ecosystem? Will Intels OneAPI work on AMD CPUs?
Intel's FORTRAN output does run on contemporary AMD fine. I have a friend who I have helped with FORTRAN make a new test programs for benchmarking.
I suggest C++ is probably as efficient which is more popular than FORTRAN which is comparatively rare these days.
There is F2C available. AMD also had a compiler https://developer.amd.com/amd-aocc/ and it supports flang along wth clang
I have 15 years of experience with mainframes and FORTRAN. If you have any issues I can help. FORTRAN IV through FORTRAN 90.
