 The Convergence of Hyperscale Data Center and High-Performance Computing Networks

(IEEE Computer. Vol 55, Nr. 7, pages 29-37, Jul. 2022)
Cover Feature Technology Predictions


The emergence of large-scale distributed data processing and complex datacenter services led to an increase of intra-datacenter traffic. The characteristics of this emerging traffic are similar to those in high-performance supercomputers. However, network technologies used in supercomputers and datacenters are quite different and it is natural to ask whether they could be unified. We discuss the differences and commonalities between these two workload types and technologies and outline a path to convergence at multiple layers. We predict that emerging smart networking solutions will accelerate that convergence.
