Video: Algorithms for Extreme-Scale Systems

Bill Gropp

Bill Gropp from the University of Illinois at Urbana-Champaign presented this talk at the Blue Waters Symposium. “The large number of nodes and cores in extreme scale systems requires rethinking all aspects of algorithms, especially for load balancing and for latency hiding. In this project, I am looking at the use of nonblocking collective routines in Krylov methods, the use of speculation and large memory in graph algorithms, the use of locality-sensitive thread scheduling for better load balancing, and model-guided communication aggregation to reduce overall communication costs. This talk will discuss some current results and future plans, and possibilities for collaboration in evaluating some of these approaches.”
