My company, Wave Computing, has built a chip with 16,000 8-bit processors on it. And we

ground in new ways to use hundreds of processors to solve problems very quickly.
It's a new way of thinking, and it makes your brain hurt. But is is what the
hardware is giving us, and there is at least another order of magnitude ahead before this
trend starts running out of steam.
This might be going a bit out-of-bounds for the mailing list, but ...
How does what you are doing compare with the work the Myrias folks were doing in the
mid-late 1980s with their n-way 680x0(?) parallel machines? Didn't they make it to
256 processors before it collapsed? I'm not aware of any papers that came out of
their work, although I would think there must have been at least a few. (Dan Wilson, are
you on this mailing list?)
I didn't have the opportunity to see what Myrias was putting together as their OS.
But I did get to play with an indirect off-shoot of their work: a massive scale (for the
time) file server, based on some of that parallel processing technology. It mimicked the
Plan9 Venti in some ways. It was very block-oriented in its external API, and I used that
lowish-level API to write a backend file store for the big-a** IMAP servers we were
developing at the time. I'm sure it would have kicked NetApp and friends around the
block, but this was the late 1990s, and we were limited by 100 Mb/s Ethernet, so there was
no real way to tell.
