Joint Laboratory People

Franck Cappello Franck Cappello leads the Grand-Large project at INRIA, focusing on high performance issues in large-scale distributed computing systems. He has initiated the XtremWeb (desktop grid) and MPICH-V (fault tolerant MPI) projects. He was the director of the Grid5000 project, a nationwide computer science platform for research in large-scale distributed systems.

He is the adjunct scientific director of ALADDIN/Grid'5000, the new four-year INRIA project aiming to sustain the Grid5000 infrastructure and to open it to cloud computing, service infrastructure, and the future internet research. He has authored papers in the domains of high-performance programming, desktop grids, and fault tolerant MPI. He is an editorial board member of the international Journal on Grid Computing, Journal of Grid and Utility Computing, and Journal of Cluster Computing. He is a steering committee member of IEEE HPDC and IEEE/ACM CCGRID.

Marc Snir Marc Snir is interested in various aspects of parallel computing and large scale distributed processing. His theoretical work in this area includes studies of parallel computation models and of parallel algorithms. His work in parallel computer architecture includes work on parallel interconnection networks and on mechanisms for efficient large scale shared memory support. His work on parallel computing software includes contributions to the design and implementation of the MPI message passing library, work on performance visualization tools and on a parallel file system. While at IBM Research he contributed to the design of the IBM SP2 supercomputer system and of several large-scale shared memory systems.

Snir's main research interest continues to be models for expressing large-scale parallel computations and mechanisms for mapping those efficiently on distributed and parallel systems. He is one of the principal investigators on the Blue Waters sustained-petascale computing project.

Laura Grigori Laura Grigori is a CR1 researcher at INRIA and Laboratoire de Recherche en Informatique of Paris-Sud 11 University, in France. Her field of expertise is high performance scientific computing, numerical linear algebra, and combinatorial scientific computing. She has performed research in various well renowned places, as INRIA, University of California at Berkeley and Lawrence Berkeley National Laboratory. She is leading several projects in developing numerical libraries for large scale parallel/multicore machines and she is a co-developer of SuperLU\_DIST, a well known parallel solver for large systems of equations.

Bill Gropp After several years at Argonne National Laboratory, Bill Gropp joined the University of Illinois at Urbana-Champaign in 2007 as the Paul and Cynthia Saylor Professor in the Department of Computer Science. His research interests are in parallel computing, software for scientific computing, and numerical methods for partial differential equations. He has played a major role in the development of the MPI message-passing standard. He is co-author of the most widely used implementation of MPI, MPICH. He is also one of the designers of the PETSc parallel numerical library, and has developed efficient and scalable parallel algorithms for the solution of linear and nonlinear equations. Gropp was named an ACM Fellow in 2006 and received the Sidney Fernbach Award from the IEEE Computer Society in 2008. He is one of the principal investigators on the Blue Waters sustained-petascale supercomputing project and the Institute for Advanced Computing Applications and Technologies' deputy director for research.

Laxmikant Kale Laxmikant Kale has been working on various aspects of parallel computing, with a focus on enhancing performance and productivity via adaptive runtime systems, and with the belief that only interdisciplinary research involving multiple CSE and other applications can bring back well-honed abstractions into Computer Science that will have a long-term impact on the state-of-art. His collaborations include the widely used Gordon-Bell award winning (SC'2002) biomolecular simulation program NAMD, and other collaborations on computational cosmology, quantum chemistry, rocket simulation, space-time meshes, and other unstructured mesh applications. He takes pride in his group's success in distributing and supporting software embodying his research ideas, including Charm++, Adaptive MPI and the ParFUM framework.

The Joint Laboratory for Petascale Computing includes researchers from the French National Institute for Research in Computer Science and Control (INRIA), the University of Illinois at Urbana-Champaign's Center for Extreme-Scale Computation, and the National Center for Supercomputing Applications. The Joint Lab is part of Parallel@Illinois.
