David Barkai

David Barkai is an HPC (High Performance Computing) computational architect for Intel corporation. He has also been a member of the Distributed Solutions Lab of Intel's Corporate Technology Group, a content architect for the Intel Developer Forum conference and a software scientist in the Microcomputer Software Lab. Before joining Intel in 1996, David worked for 25 years in the field of scientific and engineering supercomputing for Control Data Corporation, Cray Research Inc., Supercomputer Systems Inc., and NASA Ames Research Center. David holds a Ph.D. in theoretical physics and has more than 20 publications as papers, conference proceedings, and textbook contributions on the subjects of physics, numerical methods, and computer applications and architectures. Most recently he authored the book "Peer-to-Peer Computing: Technologies for Sharing and Collaborating on the Net" (Intel Press, 2001) and other articles on related topics.


High performance computing has undergone a metamorphosis in the last 15-20 years. The changes, and what they mean to the industry and the user community, will be reviewed. The HPC ecosystem that has evolved and Intel's role in it will then be described. From the Industry-relation view we will drill down to the computational, communications, and software components that Intel provides and enables. More academically, we will look at the HPC characteristics that differentiate it from other aspect of enterprise and commercial computing. This will be followed by a discussion about various, and interesting, performance metrics we observe as people select their HPC systems, and what we can learn from it. The talk will conclude with a quick survey of Intel's presence in the HPC community.
