Compilation should profit pretty linearly from more cores thrown at it. Considering the Erlang VM is very concurrency-conscious it should be a pretty natural fit.
But I'm not at all in on the intricacies of it, are there any particular CPU features (instruction set or module) it's known to take advantage of ?
You mean like vectorized instructions and such? I don't know, but if I had to guess I'd say no.
Anyway, I'm sure there are some compilation phases that won't benefit from more cores, but the bulk of the compilation seems to do so. Even though Elixir has incremental compilation, due to use of metaprogramming in the Phoenix framework sometimes even changes to a single file will trigger recompilation of hundreds of others, so I was thinking these new AMD CPUs with lots of cores could be very helpful here.
Indeed, the only compiler benchmark one typically sees are for C/C++. But Lots of developers use other languages, and it would be nice to have a cross-section because each language is so different.
BTW, how much does elixir benefit from multiple cores for compilation?
