#3This reminds me of the Ambric am2045 with 336 cores from 2007. They put 40 of these into an X-Ray machine for a total of 13,000 cores.

#4So how do you program such a beast? What progress is being made on that front?
Cache coherency seems really hard to give up on, and even CPU-GPU cache coherency is becoming the expected norm, with even ARM delivering it.

It's very hard.
In the mid 1980s there was a CPU called a "Transputer" [1] made some of the people who moved to ARM. These CPUs could be connected together in huge networks and directly talk to each other.
The network of CPU's could auto-discover its topology, but coding for so many CPU's was difficult. Some specific algorithms scaled well with the number of CPUs, but most did not.

This is "the" question. I suppose one could look at the Connection Machine: https://en.wikipedia.org/wiki/Connection_Machine The CM-2a had 4K or 8K processors and was reputedly very difficult to program.
Looked great though: http://www.corestore.org/cm2a.htm

#7Does anyone have a link or the name of another weird architecture that was posted a while ago? (~3 months maybe?) I remember that there were a large number of cores that all communicated with each other in some weird way and that they like didn't have main system memory or something like that...

Sutherlands 'Fleet'?

Yeah whatevs. This reminds me of the ICL DAP with 1024 processors from 1979...

The CM-200 looks even cooler (at least in the brochure…): http://www.corestore.org/cm200.htm
