In this video from the Blue Waters Symposium, Bill Gropp from the University of Illinois at Urbana-Champaign presents: Algorithms for Extreme-Scale Systems.
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.
