Phil, what compilers are up and working on the MacOS/M1 combination? I am aware of the NAG compiler, which has issues for commercial development (licensing) so I have been told. Also, given the staggeringly greater interest in C/C++ on all sorts of machines, I would think that portability would suggest alternate languages for new work - Python is a great control-level language, but as you mentioned you need math underneath.
