Since 2000, High Performance Computing (HPC) resources have been extremely homogeneous in terms of underlying processors technologies. However, it becomes obvious, looking at the last TOP500, that new trends tend to bring new microarchitectures for General Purpose Processors (GPPs) and new heterogeneous architectures, combining accelerators with GPP, to sustain both numerical simulation and Artificial Intelligence (AI) workflows. The present report provides a consolidated view on the current and mid-term technologies (2019-2022+) for two important components of an HPC/AI system: computing (general purpose processor and accelerators) and interconnect capabilities and provides an outlook on future trends in terms of mid-term projections about what users may expect in the coming years.
