Specifically distributed would be helped (multiple nodes).

Right now the typical paradigm is this really clunky lock-step across nodes waiting for each other (everything is blocking). If your hardware is non-homogenous (both interconnects and accelerators) or your program needs to be run in a pipelined way, you're fighting an extremely uphill battle.

Go, JavaScript etc are the usual languages of choice for this type of stuff because it's easy to express non-blocking code.
