Key power consumption metrics for general purpose microprocessors in the exascale era
By Jean-Marc Denis Chief Strategy Officer, SiPearl

Operational since January 2020, SiPearl is the French member company of the European Processor Initiative (EPI) that developed Rhea, the first HPC microprocessor designed entirely in Europe and targeting European exascale and post-exascale supercomputers. Rhea, which implements the ARM Neoverse V1 core, designed for HPC, is based on an efficient low power architecture. It is also based on innovative architectural choices designed to maximise its energy performance. In this presentation, we will detail which power indicators are relevant in the exascale age and how Rhea innovates in managing power consumption and optimising performance per watt.

Biography: Jean-Marc Denis is a renowned High-Performance Computing (HPC) expert. Previously, he was Head of Strategy, Big Data and Security within the Atos group. As such, he contributed to the launch in December 2018 of the European Processor Initiative (EPI) consortium, which is at the origin of the creation of SiPearl. He was President of EPI since its inception.

After starting as a research engineer at Matra Défense in 1990, Jean-Marc held various strategic positions in the HPC ecosystem at Silicon Graphics, Compaq, Sun Microsystems, Hewlett-Packard and Bull. Passionate about the architecture of supercomputers, for several years he taught courses dedicated to students in Master 2 in computer science at the University of Reims Champagne-Ardennes.

Jean-Marc holds an engineering degree from ENSEEIHT.
