Purdue's Anvil cluster built in partnership with Dell and AMD consists of 1,000 nodes with two 64-core AMD EPYC "Milan" processors each and delivers over 1 billion CPU core hours each year, with a peak performance of 5.1 petaflops. Each of these nodes has 256GB of DDR4-3200 memory. A separate set of 32 large memory nodes has 1TB of DDR4-3200 memory each. Anvil's nodes are interconnected with 100 Gbps Mellanox HDR100 InfiniBand.
