Recent Trends in Hierarchical N-body Methods on GPUs
Abstract:

See the newest developments in the area of hierarchical N-body methods for GPU computing. Hierarchical N-body methods have O(N) complexity, are compute bound, and require very little synchronization, which makes them a favorable algorithm on next-generation supercomputers. In this session we will cover topics such as hybridization of treecodes and fast multipole methods, auto-tuning kernels for heterogenous systems, fast tree construction based on prefix sums, fast load balancing of global trees, and more. Examples will be given using ExaFMM --an open source hierarchical N-body library for heterogenous systems developed by the speaker. (released at SC11)
