Detail of the computing racks in the fourth extension of the Jean Zay supercomputer. Acquired in 2019 by the Grand équipement national de calcul intensif (Genci), the supercomputer is named in honor of Jean Zay, politician and architect of the creation of the CNRS. The 2024 extension designed by Eviden, comprising 14 BullSequana XH3000 computing racks, increases its computing power to 125.9 petaflops (over 125 million billion operations per second). It enables national academic and industrial research communities to carry out numerical simulations using high-performance computing, and to train or specialize generative artificial intelligence models. It is one of the most eco-efficient machines in Europe, thanks to accelerated technologies (GPU) and core cooling of the computing servers. Waste heat is also reused to help heat housing on the Saclay plateau. The Jean Zay supercomputer is hosted and operated by CNRS, via the Institut du développement et des ressources en informatique scientifique (Idris).
