AMD 64-Core Rome Deployment: HLRS ‘Hawk’ at 2.35 GHz

Details for Hawk were given by the HLRS Director, Prof. Michael Resch, at a talk at the AMD booth here at Supercomputing. The title of the talk was given as ‘AMD in a Large Scale Computing System for Science and Industry’, with a focus on HLRS as a local driving force for compute as well as the work it does. The requirements for the new Hawk system were listed as high performance, professional support/collaboration, lowest possible TCO, and high level of sustainability

The key slide for us in the talk is this one:

The slide describes Hawk as a 640,000 core system using 64-core Rome CPUs. That’s 10000 CPUs, listed at a throughput of 24.06 PetaFLOPs. That gives 2.4 TeraFLOPS per CPU, which at 16 SP flops/cycle, works out about correct for a 64 core CPU for the 2.35 GHz frequency mentioned in the slide. This would appear to be a base frequency, although AMD’s Naples processors do offer a ‘constant frequency’ mode to ensure consistent performance. Main memory was listed as 665 TB, with 26 PB of disk space. It was not disclosed the breakdown of how the disk is split between NAND and HDDs.
