The Message Passing Interface (MPI) has been the dominant programming system for expressing highly-parallel technical applications for over 20 years. This success was due in part to a combination of careful design of the standard by the MPI Forum and a good match between the message-passing programming model and the distributed memory parallel computers that exploited commodity processors. However, the end of Dennard scaling and the looming end of Moore's "law" is causing major changes in computer architecture as well as creating a new community of parallel computer programmers. Will MPI continue to be relevant, or will some new programming system replace it? This talk will review the reasons for MPI's success, including the addition of new features in MPI-2, MPI-3, and planned for MPI-4, and argue why MPI will continue to be the parallel programming system for highly scalable applications.

Biography of Dr. William Gropp:
Dr. William "Bill" Gropp is Acting Director and Chief Scientist at the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign and the Paul and Cynthia Saylor Professor in the Department of Computer Science. Dr. Gropp recently co-chaired the National Academy's Committee on Future Directions for NSF Advanced Computing Infrastructure to Support U.S. Science. In 2016, the Association for Computing Machinery (ACM) and IEEE Computer Society Gropp, a professor of computer science at the University of Illinois at Urbana-Champaign the recipient of the 2016 ACM/IEEE Computer Society Ken Kennedy Award for highly influential contributions to the programmability of high-performance parallel and distributed computers. Since 2008, he has also been Deputy Director for Research for the Institute of Advanced Computing Applications and Technologies at the University of Illinois. 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, and was involved in the MPI Forum as a chapter author for both MPI-1 and MPI-2. 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 equations. 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. 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. Gropp is a Fellow of ACM, IEEE, and SIAM and received the Sidney Fernbach Award from the IEEE Computer Society in 2008. Gropp is a member of the National Academy of Engineering.
