Interesting that they’re investing in standard _AI_ toolchains, rather than standard HPC toolchains, even though I imagine Japanese supercomputing has more demand for the latter.

Last time I heard about that it was for "super computers": nearly or even faster than the alternatives with a massive energy consumption advantage.

What is an "accelerator" in this context?

you can get 8TFlops of fp64 on xeon 6980P which is 6K€ now
