Highest Scaling on JUQUEEN

18. May 2016

hi-q-logo_2016Philipp Edelmann and Friedrich Röpke (PSO group at HITS) showed during the Extreme scaling workshop 2016 at the Jülich Supercomputing Center (JSC) that the SLH code (Seven-League Hydro code), developed in the PSO group at HITS, is able to scale very efficiently on the JUQUEEN supercomputer. The HITS astrophysicists have been able to achieve 90% efficiency when increasing the number of processors from a quarter of the machine (114,688 cores) to the full machine (458,752). This impressive achievement has been awarded with a membership of SLH in the High-Q Club, a selection of scientific high-performance codes that are able to use the full JUQUEEN supercomputer efficiently.

About HITS

The Heidelberg Institute for Theoretical Studies (HITS) was established in 2010 by the physicist and SAP co-founder Klaus Tschira (1940-2015) and the Klaus Tschira Foundation as a private, non-profit research institute. HITS conducts basic research in the natural sciences, mathematics and computer science, with a focus on the processing, structuring, and analyzing of large amounts of complex data and the development of computational methods and software. The research fields range from molecular biology to astrophysics. The shareholders of HITS are the HITS-Stiftung, which is a subsidiary of the Klaus Tschira Foundation, Heidelberg University and the Karlsruhe Institute of Technology (KIT). HITS also cooperates with other universities and research institutes and with industrial partners. The base funding of HITS is provided by the HITS Stiftung with funds received from the Klaus Tschira Foundation. The primary external funding agencies are the Federal Ministry of Education and Research (BMBF), the German Research Foundation (DFG), and the European Union.
