Marc Snir is an Argonne Associate and former director of Argonne's Mathematics and Computer Science Division. His research focuses on high-performance computing, with recent work on programming models, tools, and performance analysis. The work on programming models studies methods of supporting a global name space and supporting data caching, while allowing for user control of communication and avoiding the high cost of coherence protocols. The work on tools studies refactoring tools for performance tuning. The work on performance analysis is directed at improving the scalability of climate codes.
Snir currently is the Michael Faiman and Saburo Muroga Professor in the Department of Computer Science at the University of Illinois at Urbana-Champaign.
He received his Ph.D. from Hebrew University of Jerusalem. He is an AAAS, ACM and IEEE Fellow. He has Erdos number 2 and is a mathematical descendant of Jacques Salomon Hadamard.
