BBN Butterfly
<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}.
