Recent Research Projects

  • DEEP-ER: Dynamical Exascale Entry Platform - Extended Reach
    The growing gap between I/O bandwidth and compute speed, and the need to significantly improve system resiliency are two of the most important Exascale challenges. DEEP-ER will extend the Cluster-Booster architecture of the DEEP project with a highly scalable I/O system and implement an efficient mechanism to recover application tasks that fail due to hardware errors. As a result, I/O parts of HPC codes will run faster and scale up better. These benefits will be demonstrated with the optimisation of seven HPC applications coming from different scientific and engineering areas and representing requirements of simulation-based and data-intensive HPC codes. The prototype developed and constructed by the DEEP-ER project will be used to prove the viability of the concept for 500 Petaflop class of supercomputers.

  • 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.
