Home-built CPU

I had stumbled onto the world of the homebrew CPU. To create such a computer required a detailed microarchitectural design, custom instruction set design, custom software tools like assemblers and compilers, and of course a custom circuit board. I decided to build a homebrew CPU computer of my own. It was a big mess o’ wires.

Quantum cellular automaton

Quantum dot cellular automata are a proposed improvement on conventional computer design (CMOS), which have been devised in analogy to conventional models of cellular automata introduced by John von Neumann.

the technology to reach zettaflop performance

The concept of a memory device based on self-organized quantum dots (QDs) is presented, enabling extremely fast write times, limited only by the charge carrier relaxation time being in the picosecond range.

IMP Gate

Stan has figured out a way to implement all logic functions without negation. 2-terminal devices are much easier to assembly on the nanoscale, using simple crossbars of metal, and/or self-assembly techniques. It is easy to implement all logic functions using only NAND or NOR gates, but not with just an AND or OR gate. He found the premise for this in a 160 year old philosophy book, and he calls the new gate IMP.

Petaflop

An American military supercomputer, assembled from components originally designed for video game machines, has reached 1.026 quadrillion calculations per second.

that’s 5% of a human mind, or 5% towards the singularity 🙂

Exaflop

Exaflop supercomputer. Petaflop machines don’t even ship yet.

Another problem for the institute is to reduce the amount of power needed to run a future exascale computer. “The electrical power needed with today’s technologies would be many 10s of megawatts — a significant fraction of a power plant. 1 megawatt can cost as much as $1m a year. We want to bring that down.”

2014-11-14: Towards the high petaflops

DOE has commissioned “Summit“, designed to peak at 150-300 petaFLOPS, 5x faster than the 54 petaFLOPS Tianhe-2.

2020-11-16: Fugaku has become the first 2 exaFLOPS system
2023-02-23: Zettaflop roadmap

AMD talked about getting to a Zettaflop in 2030-2035. It would need about 500 Megawatts of power. Exascale systems today consume 21MW of power.
