It's possible that the language you're looking for is Julia. https://docs.julialang.org/en/v1/manual/parallel-computing/ https://docs.julialang.org/en/v1/manual/parallel-computing/ I know almost nothing about Crystal, so I can't make a fair comparison between them. Julia is used in scientific computing, where parallel clustered processing is essential. I don't like subthreads which hijack a Language A post to talk about Language B, so I'll resist making an elaborate pitch, but Julia does fit the bill for what you're on the lookout for.
