JSC at the 9th JLESC Workshop

From 15 to 17 April 2019, JSC colleagues participated in the JLESC Workshop at the University of Tennessee (UTK), Knoxville, USA. The event marked the ninth annual meeting of the Joint Laboratory on Extreme Scale Computing (JLESC) and was the first one hosted by UTK. The Joint Laboratory brings together researchers from the seven JLESC partners – Institut National de Recherche en Informatique et en Automatique (France), the National Center for Supercomputing Applications (USA), Argonne National Laboratory (USA), Barcelona Supercomputing Center (Spain), RIKEN Center for Computational Science (Japan), UTK, and JSC. The purpose of JLESC is to address science and engineering's most critical needs in the field of high-performance computing, and to enhance the ability of its member organizations and investigators to take advantage of the ongoing evolution of extreme-scale computing technologies.

With more than 100 scientists and students from the JLESC partners, the meeting in Knoxville covered a broad range of topics that are crucial to current and future supercomputing. Together with the other participants, 14 scientists and doctoral researchers from JSC and German partner universities learnt about the latest cutting-edge research from the fields of resilience, I/O and programming models as well as numerical methods, applications, big data, and performance tools. In addition to their talks, the participants had time for fruitful discussions about their ongoing and future research ideas during project meetings, round table sessions, and a social event.

Organized by JSC, the next JLESC workshop will take place at the Gustav Stresemann Institute in Bonn from 15 to 17 April 2020, building on this successful series of internationally recognized and highly valued meetings. For more information on JLESC and the workshops, please visit
