I got paid to do the LAPACK port, back in the mid 2000s, for a federal contractor working on satellite imaging type apps. I was still a good coder, back then... Took me about a month, as I recall. Maybe 6 weeks.

But I'm one of those old-school HPC guys who believes that libraries are mostly irrelevant, and absolutely no substitute for compilers and targeted code generation.

Julia is cool, btw. It could very well end up supplanting Fortran, once they fix the poor performance code generation issues.

I think you are right on the libraries, that's why there's currently an initiative in D eco-system to have D compiler DMD as a library, and the aim is probably for compiler should be the only way to run the library without extra code [1].

I really wished any modern language should try supplanting Fortran for HPC and personally my bet is on D.
