A Data Locality Cure for Irregular Applications

Feb 18, 2014 |

Data locality plays a critical role in energy-efficiency and performance in parallel programs. For data-parallel algorithms where locality is abundant, it is a relatively straightforward task to map and optimize for architectures with user-programmable local caches.  However, for irregular algorithms such as Breadth First Search (BFS), exploiting locality is a non-trivial task. Guang Gao, a Read more…
