The connection machine combines a vast array of 1-bit processors and a
modified N-dimensional router network into a SIMD architecture. It cannot do
symmetric multiprocessing (other than simulating it, of course). And FYI, it
is not sparc based, never has been, and (RIP) never will be; it uses some
very custom silicon driven by a specialized microcontroller. Yours truly
designed the original CM-1 microcontroller documented in the DARPA proposal,
and its first host-bus interface.
