The French Alternative Energies and Atomic Energy Commission (CEA) will deploy an Atos BullSequana X1310, featuring Marvell ThunderX2 Arm processors, for its Military Applications Division (CEA/DAM).
The system will be delivered later this year to the Île-de-France CEA/DAM center, located at Bruyères-le-Châtel. With France ceasing live nuclear tests 22 years ago, the agency will use the BullSequana to help model nuclear weapons systems, and nuclear decay.
The announcement comes just a day after the US Department of Energy’s Los Alamos National Laboratory announced it had installed a Cray supercomputer with ThunderX2 Arm chips for its own classified nuclear workloads.
Atoms for Petaflops
The new supercomputer will feature 92 BullSequana X1310 blades, with three compute nodes per blade; each node features dual 32-core Marvell ThunderX2 processors at 2.2GHz, based on the Armv8-A instruction set, with 256GB of memory and Infiniband EDR interconnect.
The system is part of the Mont-Blanc 3 project, funded by the European Commission, which aims to assess the suitability of Arm-based clusters for exascale high performance computing (HPC), and help build out the necessary software ecosystem for an exascale system.
