As I have said countless times in the past:

- Moore's law is dead at the level of the transistor

- Architecture, HPC updates will keep coming for many years into the future

- AGI has already escaped Moore's law (i.e., development of a fully functional AGI will not be constrained by lack of Moore's law progress). And that's what really matters.

- Related note on AGI: it has escaped the data problem as well (as in we have the right kind of sensors: mainly cameras, microphones, and so on). That is, according to the categorization of AGI challenges in terms of hardware, data, algorithms, the only missing piece is the right set of algorithms.

We're living in an age in which AWS dwarfs all the machines on the TOP500 taken together. The TOP500 is a vestige of the cold war that needs to be retired. Similarly to how the US and the USSR used to compare their numbers of nuclear warheads, it is comparing a reserve of capacity that is probably going to be retired having brought marginal benefits at best, all in order to goad taxpayers into a futile competition.

What? The US government and others are still building these computers because they are valuable. Summit for example is nearly constantly in use at full capacity and has enabled a huge variety of research. It's hardly a "reserve" capability. Not to mention that AWS isn't really suited for a lot of the biggest supercomputing workloads...

TOP500 is not very important, but it's not meant to be much more than a simple benchmark that correlates roughly with real performance. Supercomputers aren't designed just to be number 1 on TOP500, it's a byproduct of their actual goal.

Really wish Fujitsu sold a developer kit with an A64fx chip - its the only shipping ARM chip with SVE that I know of and I would love to get my hands on one to play with.

No kidding!

I don't have any sense of how much these cost to manufacture. There ought to be a market for a A64fx based rackmount server system. If the price isn't outrageous, I'd love to see these sold as an SBC.

I cannot think of any plausible way in which Apple could have influenced the date of this announcement, but the timing, given what is expected to be announced later today, is uncanny.

Since Fugaku has been in the works for a while, I wonder if Apple just tried to choose the date of their announcement to coincide with the Top500 ranking

Why do you say that AGI has escaped Moore's law? Especially, how can you say so when you don't know what the right set of algorithms are?

yyyeah... no. A major part of what makes these machines special is their interconnect. Fujitsu is running a 6D torus interconnect with latencies well in the sub-usecond range. The special sauce is ability of cores to interact with each other with extreme bandwidth at extremely low latencies.

Thank you for this helpful info. For comparison's sake, say that you wanted to make babby's first super computer in your house with 2 laptops. That is to say, each laptop is a single core x86 system with its own motherboard and ram and ssd, and they are connected to each other in some way (ethernet? usb?) What software would one use to distribute some workload between these two nodes, what would the latency and bandw…

If you want to get experience of working with higher node counts without breaking the bank, people do case kits for raspberri pies so you can build your own cluster.

For actual computing a modern higher end processor/server will murder it but its' closer to the real world of clusters than anything (so much so that there is a company that does 100+ pi node clusters for super computing labs to test on, you can't obviously run scientific workloads but it's cheaper than using the real machine as well).

Well there obviously is interest in running simulations and other HPC applications on systems of public commercial cloud providers and there are specialized offerings including high performance interconnects, GPGPUs, large memory VMs and schedulers. Don't expect the largest of the top500 clusters to be replaced anytime soon by such, but for lesser demands people will be maintaining spread sheets and calculating the break-even point of renting vs. owning so to speak.

I'd expect in the long run, there will be only few data center operators.

But you'd think they're still reading through Django's deployment documentation which explicitly states that you don't run DBEUG = True in production.

I used to support scientists. I would not expect that unless you got the documentation published in a high-profile journal.

Heheh, from the guys who use variables such as Vo ,tm,max_p, this guy expect them to RTFM.
