NCSI Seminar: Challenges in Programming The Next Generation of HPC Systems

After over two decades of relative architectural stability for distributed memory parallel computers, the end of Dennard scaling and the looming end of Moore's "law" is forcing major changes in computing systems.  Can the community continue to use programming systems such as MPI for extreme scale systems? Does the growing complexity of compute nodes require new programming approaches? Can performance portability be achieved? Are new I/O models required? This talk will discuss some of the issues, with emphasis on internode and intranode programming systems and the connections between them.

William Gropp

William Gropp received his B.S. in Mathematics from Case Western Reserve University in 1977, a MS in Physics from the University of Washington in 1978, and a Ph.D. in Computer Science from Stanford in 1982. He held the positions of assistant (1982-1988) and associate (1988-1990) professor in the Computer Science Department at Yale University. In 1990, he joined the Numerical Analysis group at Argonne, where he was a Senior Computer Scientist in the Mathematics and Computer Science Division, a Senior Scientist in the Department of Computer Science at the University of Chicago, and a Senior Fellow in the Argonne-Chicago Computation Institute. From 2000 through 2006, he was also Deputy Director of the Mathematics and Computer Science Division at Argonne. In 2007, he joined the University of Illinois at Urbana-Champaign as the Paul and Cynthia Saylor Professor in the Department of Computer Science. From 2008 to 2014 he was the Deputy Director for Research for the Institute of Advanced Computing Applications and Technologies at the University of Illinois. In 2011, he became the founding Director of the Parallel Computing Institute. In 2013, he was named the Thomas M. Siebel Chair in Computer Science. In 2016, he was appointed as Acting Director of the National Center for Supercomputing Applications (NCSA), and in 2017, became Director of NCSA. His research interests are in parallel computing, software for scientific computing, and numerical methods for partial differential nist-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, and was involved in the MPI Forum as a chapter author for MPI-1, MPI-2, and MPI-3. He has written many books and papers on MPI including "Using MPI" and "Using MPI-2". 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 nist-equations. With the other members of the PETSc core team, he was awarded the SIAM/ACM Prize in Computational Science and Engineering in 2015. Gropp is a Fellow of AAAS, ACM, IEEE, and SIAM, and a member of the National Academy of Engineering. He received the Sidney Fernbach Award from the IEEE Computer Society in 2008, the SIAM-SC Career Award in 2014, and the Ken Kennedy Award from the ACM and the IEEE Computer Society in 2016.
