Joint Laboratory on Extreme Scale Computing (JLESC)

On 9 January 2015, JSC became a full member of the Joint Laboratory on Extreme Scale Computing (JLESC). The Joint Laboratory brings together researchers from the Institut National de Recherche en Informatique et en Automatique (Inria, France), the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champagne (NCSA, USA), Argonne National Laboratory (ANL, USA), Barcelona Supercomputing Center (BSC, Spain), RIKEN (Japan), and JSC. Since this is truly a high-level consortium in supercomputing, JSC felt greatly honoured by being invited to join as a full partner.

The objectives of JLESC are to initiate and facilitate international collaborations on state-of-the-art research related to computational and data-focused simulation and analytics at extreme scales. JLESC promotes original ideas, publications, research, and open-source software, and aims to address the most critical issues in advancing computing from petascale to extreme scales. JLESC research topics include parallel programming models, numerical algorithms, parallel I/O and storage systems, data analytics, heterogeneous computing, resilience, and performance analysis.

The collaborative work within JLESC is organized in joint projects between two or more partners. These include reciprocal research visits, joint publications, and software releases. The results of these projects are discussed during biannual workshops, where new ideas and collaboration opportunities are also presented.

JSC is represented in JLESC by Steering Committee member Prof. Thomas Lippert and by Dr. Robert Speck, one of the Executive Directors. For more information visit the official JLESC website at
