At the International Supercomputer (ISC 2022) trade show, HPE demonstrated blade systems that will power two exascale supercomputers set to come online this year — Frontier and Aurora. Unfortunately, HPE had to use sophisticated and power-hungry hardware to get unprecedented computing performance. Hence, both machines use liquid cooling, but even massive water blocks cannot hide some interesting design peculiarities the blades feature. 

Both Frontier and Aurora supercomputers are built by HPE using its Cray EX architecture. While the machines leveraged AMD and Intel hardware, respectively, they use high-performance x86 CPUs to run general tasks, and GPU-based compute accelerators to run highly parallel supercomputing and AI workloads.
