What does it take to build a "top-ten" supercomputer? What exactly goes into a system designed to meet the biggest challenges of computational researchers?

Frontera at TACC is made up of 8,368 Intel "Cascade Lake" compute nodes, together with 4 login nodes, 16 large memory nodes, and 90 single-precision NVIDIA GPU nodes. (The total includes 360 compute nodes that were added to the system in early 2021.) Networking between the nodes is handled by several tiers of Mellanox HDR InfiniBand switches. All the above nodes are manufactured by Dell.
