ExaCluster Laboratory (ECL)

ECL logo

The ExaCluster Laboratory (ECL) has been established in May 2010 by the Forschungszentrum Jülich, Intel and ParTec. In ECL the three partners are conducting R&D to guarantee affordable and reliable operation of HPC Clusters reaching Exascale levels of performance. The lab employs in total a dozen researchers from Juelich, Intel and ParTec and is expected to grow its staff over time.

The ExaCluster Lab touches hardware and software topics: processor and system architecture for extreme scalability and power efficiency, highly efficient and robust communications and management middleware, scalable performance analysis tools, and top tier applications from science and engineering.
Marquee projects with substantial ECL involvement include the Framework 7 project DEEP (“Dynamical Exascale Entry Platform”) running since December 2011 and its sibling DEEP-ER (“DEEP - Extended Reach”) which started in October 2013. As a centerpiece of the ECL’s research the DEEP project investigates a new class of HPC Clusters based on Intel® Xeon Phi™ which pushes back the scalability limitations expressed by Amdahl’s law and enables application sections to be run at exactly the right level of parallelism.
Current work of ECL focuses on the design, realisation, and evaluation of DEEP’s Cluster-Booster Architecture.

Main aspects of this work are:

  • Design and construction of the DEEP System: the first prototype of the DEEP Cluster Booster Architecture
  • Design and development of the DEEP programming environment
  • Address scalability challenges and improvements needed for cluster computing to run at Exascale
  • Development of new resiliency techniques for Exascale computing
  • Preparing scientific applications for Exascale: porting to the DEEP Architecture
  • Evaluation of novel processor architectures and early porting of scientific applications
