  • DEEP-EST: Dynamical Exascale Entry Platform - Extreme Scale Technologies
    In the spirit of DEEP and DEEP-ER, DEEP-EST will present the Modular Supercomputer Architecture (MSA): a single heterogeneous system with individual compute modules. Each of the modules is of potentially large size and specifically designed for various workloads. The MSA interconnection network is based on EXTOLL, encapsulated in a dense form factor box called FabriCube. In cooperation with EXTOLL, the Computer Architecture Group for the design and implementation of 'Network Attached Memory' and the 'Global Collective Engine'. These two components, tightly integrated with the EXTOLL network, serve two different use cases: Network Attached Memory (NAM) provides network-speed access to up to 64TB non-volatile storage. It can therefore serve as intermediate storage target to e.g. hold machine learning training data. Its functionality is complemented by application specific processing elements to execute small compute kernels. The Global Collective Engine (GCE) on the other hand is equipped with two DDR4 memory DIMMs. These function as a buffer for data elements required to process global collective operations "in the network". Collective operations are among the most commonly used communication patterns in HPC applications. Hence, accelerating these operations will likely improve application runtimes and system efficiency. The DEEP-EST project has officially started in July 2017 and is expected to end in June 2020.

  • EXTOLL – Extreme low latency Interconnect
    EXTOLL introduces a new interconnection network architecture for High-Performance Computing, which brings a rich set of features to the HPC application space. The EXTOLL solution integrates host-interface, network interface controller and network functions within a single chip. This single chip solution enables power efficiency and lower total cost of ownership. 
  • GreenICE – Immersion cooled electronics
    The GreenICE System is based on the principle of 2-phase immersion cooling. The electronic assemblies, such as server modules, are arranged standing up in a chassis filled with 3M™ Novec™ 649 Engineered Fluid.
  • openHMC - An open-source Hybrid Memory Cube controller
    openHMC is a vendor-agnostic, AXI-4 compliant Hybrid Memory Cube (HMC) controller that can be parameterized to different data-widths, external lane-width requirements, and clock speeds depending on speed and area requirements. The main objective of developing the HMC controller is to lower the barrier for others to experiment with the HMC, without the risks of using commercial solutions.
