No, not quite — their interconnects are very impressive. It's true that they don't make CPUs anymore, but that stopped making sense a long time ago. If you want to be a supercomputer company these days the value is in the interconnect and software.

- wmf 10y agoBut most Cray systems, like the ones in this article, don't use Cray interconnects.

- jabl 10y agoCray sold their interconnect IP to Intel a few years ago. But yeah, Aries is impressive.
- inopinatus 10y agoSurely also in the cooling systems. I remember on my visits to the Edinburgh supercomputing center, the quip was that Cray were a refrigeration company first. Like Tesla is a battery manufacturer.
- gbrown_ 10y agoThat will have been for HECToR, an old XE system. They use the ECOphlex system which is a liquid evaporative phase-change cooling system using tetrafluoroethane. The current XC line of supercomputers from Cray utilize more conventional cooling methods.
- inopinatus 10y agoOh, this was much further back. The last time I set foot in the JCMB was around 1996. I think the main workhorses of the day were a Cray T3D/T3E. ISTR there was a Y-MP in there as well.
