HPE Cray EX
The exascale platform under Frontier and El Capitan.
You're looking at a system record: an assembled machine — a server or a whole rack — with what's inside it and where it's deployed.
Cray EX is HPE's liquid-cooled supercomputing cabinet line with the Slingshot interconnect — the architecture of the US exascale systems and many national AI machines. It represents the HPC lineage of AI infrastructure: government labs ran liquid-cooled, power-dense computing a decade before hyperscalers had to.
Specifications & key facts
Each figure is labeled by basis: vendor spec, vendor claim, reported, estimate, or official. "Not publicly disclosed" means exactly that — we never invent values.
