(measured [1]) | The French Alternative Energies and Atomic Energy Commission (CEA) have deployed an Atos BullSequana X1310, featuring Marvell ThunderX2 Arm processors, for its Military Applications Division (CEA/DAM). 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. This system is the commercial version of the prototype developed and built by Atos as part of the Mont-Blanc project for tests and evaluation. |
