Mont-Blanc 2020

European Approach Towards Energy Efficient High Performance Computing

The Mont Blanc projects aim to assess the potential of Arm-based clusters to address Exascale HPC needs, and develop the corresponding software ecosystem. The latest project in the series, the Mont-Blanc 2020 project, intends to pave the way to the future low-power European processor for Exascale.

Mont-Blanc 2020's target is to reach exascale-level power efficiency (50 Gflops/Watt at processor level) with a second generation planned for 2022. Therefore, the project will:

  1. define a low-power System-on-Chip (SoC) implementation targeting Exascale, with built-in security and reliability features;
  2. introduce strong innovations to improve efficiency with real-life applications and to outperform competition (vector instruction implementation, memory latency and bandwidth, power management, 2.5D integration);
  3. develop key modules (IPs) needed for this implementation;
  4. provide a working prototype demonstrating MB2020 key components and system level simulations, with a co-design approach based on real-life applications;
  5. explore the reuse of these building blocks to serve other markets than HPC.
