“Everything is interwoven” and Multi-X challenges are everywhere, claims Prof Hans-Joachim Bungartz.

His talk will focus on Multi-X problems in Computational Science and Engineering – multi-physics problems, multi-scale models, multi-level algorithms, or multi-core systems – and possible co-design strategies to tackle and solve these issues. The seminar lecture aims to present examples from recent research that show how a well-balanced approach can lead to significant improvements in application performance, and offer a perspective for Skoltech’s CDISE CREI – both as a hub of methodical Computational Science and Engineering research and as a cross-sectional unit with tight links to other CREI’s.

 

Title: «CHALLENGES IN ADVANCED COMPUTING: MULTI-THIS AND MULTI-THAT»

Speaker: Prof Hans-Joachim Bungartz, Technische Universität München (TUM)

When: June 20, 2014 12.30 – 14.00

Where: Beijing-1 Auditorium, China cluster, Skolkovo School of Management

SEMINAR ABSTRACT: There are a lot of challenges Computational Science and Engineering and High-Performance Computing are confronted with, many of them being of “Multi-X” type: multi-physics problems, multi-scale models, multi-level algorithms, or multi-core systems are just some prominent representatives. Others are multi-modality or multi-dimensionality, that are especially related with the data involved – which underlines the fact that the computational paradigm currently sees another incarnation: after simulation and optimization now data exploration.

Each of these topics is demanding in itself. The big challenge, however, results from the fact that everything is interwoven, that progress on the road to exa-scale computing including large-scale data analysis requires the combination of the most advanced models, algorithms, and systems – i.e., there is need for a co-design perspective that goes beyond classical application or system tuning or algorithm development.

The talk will focus on the multi-X challenges and possible co-design strategies, it will give a couple of examples from our recent research that show how a well-balanced approach can lead to significant improvements in application performance, and it will provide a perspective for SkolTech’s CDISE CREI – both as a hub of methodical CSE research and as a cross-sectional unit with tight links to other CREI’s.

SPEAKER INTRODUCTION: Hans-Joachim Bungartz is a full professor of informatics and mathematics at Technische Universität München (TUM), where he holds the Scientific Computing chair in the informatics department. Dr. Bungartz obtained diploma (master’s) degrees in mathematics and informatics, his PhD and his habilitation in informatics from TUM. He was managing director of the Bavarian Consortium on HPC, associate professor of mathematics at Universität Augsburg, full professor of informatics at Universität Stuttgart, and returned to TUM in 2005.

Since 2008, he has also been affiliated with the Dept. of Mechanical Engineering of University of Belgrade, Serbia.

Since 2013, Dr. Bungartz has served as Dean of Informatics as well as TUM Graduate Dean, heading TUM Graduate School and being in charge of doctoral education TUM-wide, across all disciplines. In both functions, he is member of TUM’s Extended Board of Management.

Dr. Bungartz has served or serves on editorial boards such as SIAM’s Journal of Scientific Computing or Springer’s Numerische Mathematik, and he was a member of the scientific directorate of Leibniz Institute for Informatics Schloss Dagstuhl.

From 2006 to 2013, he chaired the Commission for IT Infrastructure of the German Research Foundation (DFG). He is involved in numerous national and international review and advisory board activities. In 2011, he was elected chairman of the German National Research and Educational Network (DFN).

Finally, Dr. Bungartz is a board member of Leibniz Supercomputing Centre, one of three national HPC centers. His research interests are where CSE, scientific computing, and HPC meet. He works on parallel numerical algorithms, hardware-aware numerics, high-dimensional problems, data analytics, and aspects of HPC software, with fields of application such as CFD, quantum chemistry, physics, or finance. Most of his projects have been collaborative and interdisciplinary ones. For example, he coordinates DFG’s new Priority Program Software for Exascale Computing as well as the computational projects of the KAUST-TUM partnership. Dr. Bungartz published a large number of peer-reviewed papers, co-authored several textbooks in German and English, and won the ISC PRACE Award in 2013.
