Gilles, Thank you so much for the quick response! openMPI installed by brew is compiled on gcc and gfortran using the original compilers by Apple. Now I haven't figured out how to use this gcc openMPI for the inversion software :( Given by your answer, I think I'll pause for now with the M1-intel compilers-openMPI route and switch to an intel cluster until someone figured out the M1 chip problem ~
Thanks again for your help!
