>ABSTRACT:
>The Message Passing Interface (MPI) has been a remarkably successful 
>programming model for parallel computers.  However, ten years have 
>elapsed since the MPI 2.0 standard was released.  Much has changed 
>in that time, including massive increases in node count, experiences 
>with new programming models, and the shift to multi- and many-core 
>processors.  In particular, much more is known about the performance 
>costs and challenges in MPI implementations, particularly for MPI 
>one-sided operations, MPI I/O, and the hybrid programming model of 
>MPI and threads.  This talk will describe some recent performance 
>results for MPI implementations and discuss the challenges that they 
>represent.  Alternative programming models that combine MPI with 
>threads (on a node) or partitioned global address space languages 
>like UPC offer both opportunities and challenges; this talk will 
>review some of the possible models and their potential.  The talk 
>will conclude with a discussion of how the MPI Forum, the informal 
>group that defined MPI and that has begun meeting again, is 
>addressing the evolution of MPI.

>ABOUT THE SPEAKER:
>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. 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. Gropp was named an ACM 
>Fellow in 2006.
