There is also Soap Bubble Computing, or various form of annealing computing (like quantum annealing or Adiabatic quantum computation), where you set up your computation as the optimal value of a physical system you can define.

This reminds me of a talk I went to at the 2020 ALIFE conference, in which the speaker presented an infinitely-scalable architecture called the "Movable Feast Machine". He suggested relinquishing hardware determinism - the hardware can give us wrong answers and the software has to recover, and in some cases the hardware may fail catastrophically. The hardware is a series of tiles with no CPU. Operations are local and…

hello,

great collection of interesting links - kudos to all! :=)

idk ... but isn't the "general" architecture of most of our computers "von neumann"!?

* https://en.wikipedia.org/wiki/Von_Neumann_architecture

but what i miss from the various lists, is the "transputer"-architecture / ecosystem from INMOS - a concept of heavily networked arrays of small cores from the 1980ties

about transputers

about INMOS

i had the possibility to take a look at a "real life" ATW - atari transputer workstation - back in the days at my university / CS department :))

mainly used with the Helios operating-system

to be programmed in occam

the "atari transputer workstation" ~ more or less a "smaller" atari mega ST as the "host node" connected to an (extendable) array of extension-cards containing the transputer-chips:

Here are some architectures that might interest you. Note these are links that lead to rabbit holes. 1. Transmeta: https://en.wikipedia.org/wiki/Transmeta 2. Cell processor: https://en.wikipedia.org/wiki/Cell_(processor) 3. VAX: https://en.wikipedia.org/wiki/VAX (Was unusual for it's time, but many concepts have since been adopted) 4.

I wouldn't say the VAX was unusual even though it was a pathfinder in that it showed what 32-bit architectures were going to look like. In the big picture the 386, 68040, SPARC and other chips since then have looked a lot like a VAX, particularly in how virtual memory works. There's no fundamental problem with getting a modern Unix to run on a VAX except for all the details.

Z is definitely interesting from it's history with the IBM 360 and its 24 bit address space. (24 bit micros existed in the 1980s such as the 286 but I never had one that was straightforward to program in 24 bit mode) which, around the time the VAX came out, got expanded to 31-bits

Why the Cell processor did not had success in AI/DL applications?

It was released a decade and a half too early for that, and at the time it was too weird and awkward to use to stay relevant once CUDA caught on.

That's something I was also curious about and it turns out Arduinos use the Harvard architecture. You might say Arduinos are not really "computers" but after a bit of googling I found an Apple II emulator running on an Arduino and, well, an Apple II is generally accepted to be a computer :)
