BBN Butterfly
<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
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.
