I never had the pleasure of playing with Transputers, but it sounds nice.
Of course, I'd want the networking to be Ethernet/IP centric these days.

You mean like INMOS's Transputer architecture from back in the late
eighties and early nineties?  Each processor had a thread scheduling and
message passing microkernel implemented in its microcode, and had four
bi-directional links to other processors, so you could build a grid.
They designed the language Occam along with it, to be its lowest level
language; it and the instruction set were designed to match.  Occam has
threads and message passing as built-in concepts, of course.
