- 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.
