Anton 2 is a second-generation special-purpose supercomputer for molecular dynamics simulations that achieves significant gains in performance, programmability, and capacity compared to its predecessor, Anton 1. The architecture of Anton 2 is tailored for fine-grained event-driven operation, which improves performance by increasing the overlap of(More)
Special-purpose computing hardware can provide significantly better performance and power efficiency for certain applications than general-purpose processors. Even within a single application area, however, a special-purpose machine can be far more valuable if it is capable of efficiently supporting a number of different computational methods that, taken(More)
We have parallelized and optimized an agent-based simulation of emergent flocking behavior for two shared-memory architectures: the POWER5 and the Cell Broadband Engine. The goal of this study was to explore the affordances and trade-offs of both architectures and their available APIs, especially for addressing the load-balancing issues caused by the uneven(More)
