there were the '' languages on the connection machine. in C for example, 'shapes', which were cartesian arrays of values were part of the type system. communications operations were explicit through the use of indirection on these indices. I doubt its the case on a modern gpu, but aside from the router, performance on the CM was deterministic so you really could understand what you were going to get from the source. completely agree with you, general parallel programming languages are a thing and really pretty valuable to try to exploit all that machinery. Chapel is the only recent work I'm familiar with.
