< computer > A supercomputer developed at BBN Technolgoies , named after the "butterfly" multi-stage switching network around which it was built. It could have up to 512 CPU s 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 68020 s. The later TC-2000 models used up to 512 Motorola 88100 s.
Language developed for, or ported to, the BBN Butterfly were Butterfly Common LISP , Butterfly Scheme , Delirium , and MultiScheme .
