DIY 1980s "Non-Von" Supercomputer
Brietech writes "Ever wanted to own your own supercomputer? This guy recreated a 31-processor SIMD supercomputer from the early 1980s called the 'Non-Von 1' in an FPGA. It uses a 'Non-Von Neumann' architecture, and was intended for extremely fast database searches and artificial intelligence applications. Full-scale models were intended to have more than a million processors. It's a cool project for those interested in 'alternative' computer architectures, and yes, full source code (Verilog) is available, along with a python library to program it with." Hope the WIPO patent has expired.

Everything that you wanted to know and more. An interesting read.

I'm perfect in every way, except for my humility.
Folks just don't understand what FPGA's do.
"So, that's neat and all but did I misunderstand something. His model doesn't seem that powerful unless he was using modern processors?"
It's implemented in HARDWARE. Everything runs in parallel. To do the same on a "modern" processor, would require 300-400Mhz. A FPGA running at a [modest] 25Mhz could get the same or better performance.
"I can't help but wonder if this couldn't be emulated for a fraction of the price. Are there any virtualization systems out there that could accomplish what this guy did? I imagine something along the lines of GNS3 might work..."
FPGA's are cheap. A Spartan-3 board can be had for 100-200, and probably hold 2-3 32 node cpu's.
Programmers just don't understand the difference between say verilog, and C/C++/Java.
verilog is the basic building block of CPU's. Everything is done in PARALLEL by default, while in C++/Java everything is done SERIALLY.
Wasn't the transputer an example of this architecture? I'm old enough to be able to say "Get off my lawn!" and remember when the transputer came out; it caused quite a stir.
The transputer was a RISC-ish CPU with 4 high speed DMA/serial links allowing it to be easily connected to other Transputers (each with its own local memory) to form a network. As such, it could be used to build a large MIMD system - not a SIMD one.
Transputers (+ the Occam language) supported multi-threaded programming with very fast context switches and, for its time, they also had very good FP performance when compared to the contemporary x86+float coprocessor.
Uhhh... right here. Now don't say I didn't warn you, but it's pretty relevant.
Link attempts to install a virus; need to kill his comment.
