For context, *Lisp (pronounced "star Lisp") was a parallel programming extension to lisp on the Connection Machine System, which was a series of supercomputers. The front-end machine for talking to the CM was either a Unix box or a Symbolics Lisp machine.
Do you know how similar the Connection Machine was to a modern GPU? The descriptions I've seen sound similar, but I don't really know enough to say how similar.
They aren't targeting similar hardware, so aren't very similar. The constructs introduced by *Lisp are designed mainly for issuing SIMD-style instructions to a grid of 256+ processors (in some versions, 10k+).
