Keynote Speakers

Tuesday, May 10, 2011: Satoshi Matsuoka
Professor of Computer Science, Tokyo Institute of Technology, Japan.


Satoshi Matsuoka is a full Professor at the Global Scientific Information and Computing Center of Tokyo Institute of Technology, where he leads the Research Infrastructure Division Solving Environment Group. He pioneered Grid computing research in Japan in the mid-1990s along with his collaborators, and currently serves as sub-leader of the Japanese National Research Grid Initiative (NAREGI) project, which aims to create middleware for next-generation CyberScience Infrastructure. He was the technical leader in the construction of the TSUBAME supercomputer, which became the fastest supercomputer in Asia-Pacific, ranking 7th on the SC500 list in June 2006. The next generation TSUBAME 2.0 became the first petascale supercomputer in Japan, having a computing power of 2.4 petaflops. TSUBAME 2.0, featuring a.o. three state-of-the-art GPUs per compute node, entered the SC500 list at rank #4, and the Green500 list at rank #2, in November 2010.

He has been program-, area-, and general chair of several international conferences, including CCGrid, Grid, and SC. He will also serve as Communities Program Chair for SC2011. He served as Steering Group member and Area Director of the Global Grid Forum during 1999-2005. He has won several awards incl. the Sakai award for research excellence from the Information Processing Society of Japan (1999), and the JSPS Prize (Japan Society for Promotion of Science) from his Royal Highness Prince Akishinomiya (2006).

Thursday, May 12, 2011: Rosa M. Badia
Manager Grid Computing and Clusters Group, Barcelona Supercomputing Center, Spain.


Rosa M. Badia received the B.Sc. and Ph.D. degrees in computer science from the Technical University of Catalonia, Barcelona, Spain in 1989 and 1994. From 1989 till 2007 she has been lecturing at the Technical University of Catalonia on computer organization and architecture, and VLSI design. She held an Associate Professor position at the Department of Computer Architecture, Technical University of Catalonia from 1997 till 2008. Since 2005 she has been Manager of the Grid Computing and Clusters Group at the Barcelona Supercomputing Center, a position that she currently holds full-time.

Her research interests include performance prediction and modeling of MPI applications, programming models for multi-core architectures and programming models for Grid environments. She has participated in several international research project, including the EC-funded projects SEP-Tools, DAMIEN, CoreGRID, BEinGRID, Brein, XtreemOS, OGF-Europe and (at a worldwide level) in the LAGrid project.

Theme Presentations

Monday, May 9, 2011: Simon Portegies Zwart
Professor of Computational Astrophysics, Leiden University, The Netherlands.


Simon Portegies Zwart obtained his Ph.D. in 1992 from Utrecht University, and held posi- tions at Tokyo University, MIT and the University of Amsterdam. In 2009 he was appointed full professor at Leiden University. He is a computational astrophysicist with a specific interest in gravitational interactions at all scales; ranging from planetary dynamics and star clusters to galaxy dynamics and large-scale structure formation in the Universe. He pio- neered the evolution of star clusters by incorporating additional physics in numerical simulation models of dense star clusters, and the use of GPUs for high-performance N-body simulations. He also pioneered high-performance simulations on grids of supercomputers, and multiphysics software environments in which gravitational solvers are combined with stellar evolution, hydrodynamics and radiative transport.

He has published over 120 astrophysics papers, several of which have been published in Nature. He has won a.o the Schmeits Prize for the most outstanding Dutch astronomer (2007) and received both a JSPS (1997) and a Hubble Fellowship (1998), and he is also a key researcher of the Netherlands Research School for Astronomy (NOVA). In December 2008 he was awarded the prestigious NWO VICI grant.

Tuesday, May 10, 2011: Henri Bal
Professor of Computer Science, VU University, Amsterdam, The Netherlands.


Henri Bal received his Ph.D in 1989 from VU University, Amsterdam, under supervision of Prof. Andrew Tanenbaum. His work on optimizing compilers led to the development of the Orca programming language, one of the first programming languages intended for large-scale cluster computers. His PhD thesis was sufficiently influential for it to be published by Prentice-Hall as a book entitled "Programming Distributed Systems". After his Ph.D., he was a postdoctoral fellow at MIT in Cambridge, Massachusetts, at the University of Arizona in Tucson, Arizona, and at Imperial College in London. He then came back to the Vrije Universiteit as an Assistant Professor. Shortly thereafter he was awarded a 'Pionier' grant from the Dutch National Science Foundation, the most prestigious award then available to young researchers. In 1998 he became a Full Professor, leading a research group on High-Performance and Distributed Computing.

He has published over 100 scientific papers in leading computer science conferences and journals, and has been a program committee member of various international conference (incl. a.o. HPDC, SC). He was also the driving force behind the acquisition and use of three large distributed cluster computers called the Distributed ASCI Supercomputer (DAS), the lastest generation of which (DAS-4) has been operational since December 2010. As some of its distinguishing features, DAS-4 employs a number of HPC accelerators (e.g., various GPU types) and a novel internal wide-area interconnect based on light paths, called StarPlane.

Wednesday, May 11, 2011: Emmanuel Jeannot
Senior Research Scientist, INRIA Bordeaux Sud-Ouest, France.

Slides: Experiment Driven Research
Slides: The art of computer science analysis

Emmanuel Jeannot received his Ph.D. in 1999 from the Ecole Normale Suprieur de Lyon (LIP laboratory). After his PhD he spent one year as a postdoc at the LaBRI laboratory in Bordeaux. From September 1999 to September 2005 he was assistant professor at the Universit Henry Poincar, Nancy 1. From 2000 to 2009 he performed his research at the LORIA laboratory. From January 2006 to July 2006 he was a visiting researcher at the University of Tennessee, ICL laboratory. After having been a research scientist at INRIA Nancy Grand-Est, since September 2009 he holds the same position at INRIA Bordeaux Sud-Ouest and at the LaBRI laboratory since September 2009.

His main research interests are scheduling for heterogeneous environments and grids, data redistribution, algorithms and models for parallel machines, grid computing software, adaptive online compression and programming models. Among many other international responsibilities, he is the leader of the European COST Action IC0805 (ComplexHPC: Open European Network for High-Performance Computing in Complex Environments). Also, he is the general (co-) chair of the 17th International European Conference on Parallel and Distributed Computing (Euro-Par 2011), held in Bordeaux, France.
