It was at the NSCEE (National Supercomputing Center for Energy and the Environment) installation at UNLV for Yucca mountain. There were two vector processors and an amazing 5GB SSD. The OS was UNICOS, a successor of System V and COS (Cray OS), and a user was actually fully swapped out on context switches.
The SSD wasn't new by any means. A decade earlier the Cray-1M optionally could have had an SSD.
- lvh 6y agoTo be clear, we're talking about battery-backed RAM (specifically MOS RAM) there, right?
- IncRnd 6y agoI don't know how the solid state storage was implemented. There are bunches of Cray brochures on the Internet that might have that information.
- monocasa 6y agoIt's not an SSD; they're referring to their main RAM as solid state storage to differentiate it from core memory.

- walrus01 6y agoI don't think it was battery backed by anything in the Cray, though I could be wrong. The general idea being that the Cray would be installed in a facility that should have massive whole AC circuit, true online type UPS, and generators backing that up.
- monocasa 6y agoI think they're talking about the (not battery backed) SRAM, that would have been referred to as solid state storage to differentiate it from core memory technology. The gigabytes of SRAM used as main RAM you could stick on a Cray was a key differentiator for the platform (and would be still today).
