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

HITS, the Heidelberg Institute for Theoretical Studies, was established in 2010 by 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, mathematical, and computer sciences. Major research directions include complex simulations across scales, making sense of data, and enabling science via computational research. Application areas range from molecular biology to astrophysics. An essential characteristic of the Institute is interdisciplinarity, implemented in numerous cross-group and cross-disciplinary projects. The base funding of HITS is provided by the Klaus Tschira Foundation.
