<computer> A supercomputer developed at BBN Technologies, named after the
"butterfly" multi-stage switching network around which it was built. It could
have up to 512 CPUs connected to allow every CPU access to every other CPU's
memory, albeit with about 15 times the latency than for its own. The earlier
GP-1000 models used up to 256 Motorola 68020s. The later TC-2000 models used up
to 512 Motorola 88100s.
Language developed for, or ported to, the BBN Butterfly were Butterfly Common
LISP, Butterfly Scheme, Delirium, and MultiScheme.
