K was basically a one-off, but you could buy systems with similar technology, though they weren't common outside Japan. A64FX machines are appearing in the West now. There was a recent substantial award for one to a UK academic/Met Office consortium, in which there's some interest.
- linksnapzz 6y agoYeah, by K-machine I mean any of the PrimeHPC-FX class systems using SPARC64-V derivatives; I'm sure they sold a few outside Japan, but I don't think that not having the wider global market would've deterred Fujitsu from making them. I know some of Fujitsu's A64 modules were making it into Cray systems as well; isn't that what U. Bristol has?
- gnufx 6y agoI'd forgotten the name PrimeHPC-FX. You would think they'd be worth looking at if you knew about K. I don't remember exactly what Bristol have got now. (Its not so easy to get detailed info on UK Tier 2 systems, even if you're supporting one.) I know it's using Infiniband, not Tofu as they're mostly interested in single-node performance for some reason, but I don't know what other than the chips come from Fujitsu. It may be right that they're not doing much with systems. There does seem to be more interest this time round, at least.
