Pezy and the other Japanese native chips are first and foremost about HPC. The world may have picked up AI in the last 2 years, but the Japanese chipmakers are still thinking primarily about HPC, with AI as just one HPC workload. These Pezy chips are also made for large clusters. There is a whole system design around the chips that wasn't presented here. The Pezy-SC2, for instance, was built around liquid immersion cooling. I am not sure you could ever buy an air-cooled version.

>liquid immersion cooling Is the whole board submersed in liquid? Or just the processor?

A Brick consists of a backplane board, 32 PEZY-SC2 modules, 4 Intel Xeon D host processors, and 4 InfiniBand EDR cards. Modules inside a Brick are connected by hierarchical PCI Express fabric switches, and the Bricks are interconnected by InfiniBand."

    I remember some offhand remarks on that. Apparently the rooms for these systems had cheap ladles hanged somewhere and engineers would have fun scooping out water puddles collecting on top of enclosures full of fluorinert coolants. That's tanks full of PFAS in layman's terms...

      But, importantly, nontoxic PFAS.

> Pezy-SC2, for instance, was built around liquid immersion cooling Well that was a disappointing end to a sentence. I was hoping another company would invest a few million in HPC to play SC2! https://www.youtube.com/watch?v=UuhECwm31dM https://www.youtube.com/watch?v=UuhECwm31dM

  I think they just do what they have done well. LLMs don't take demand away from HPC, like physics and weather simulations. Arguably if some of their competitors divert resources to LLMs it might even be better for them.
