Research: Connection Machine (*Lisp and C*), SIMT done right--*Feyman* was behind that bad boy.  If you scale this thing, and interconnect with hypercube topology, you might get a connection machine emerging.

But, OK given your anti-SMT logic why not throw away Vulkan, the descendent of OpenGL, meant for SIMD GPU designs?  For the prototype use OpenGL 3.1.  You have painted yourself back into the original design case for OpenGL anyway.  It would run Curv and my Open Inventor 3D Lisp desktop.  Doug pointed out that we might have to add a patch for "noise()".  Many, many people know OpenGL and use it everyday.  It's like the "make" thing I guess, will we ever get rid of Autotools?
