And their async/await is being redesigned IIRC, but at least the last version would make for a low overhead (in both developer time and runtime) way to parallelize any of the above. In the old version it was totally trivial to write a high performance parallel variant (knight's move and whatnot) sudoku solver, and I doubt the new version will be any worse. Not that the interior of a linear algebra operation is often the best place to apply parallelization, but if you had a good reason to do so it wouldn't be hard.

I'm not aware of anything in particular that would make multi-machine computations even slightly less painful than other languages, but maybe someone can chime in here with ideas.

C++ / Eigen performs a lot of optimizations that you might expect from a Fortran compiler. For example, it ability to broadcast and perform reductions is pretty slick, e.g.:

        X.noalias() = (A - B).colwise().squaredNorm().mean();

Short of having tensor cores, this does a good job of static optimization for underlying vectorization support.
