Cache-efficient dynamic programming algorithms for multicores
Rezaul Chowdhury, Vijaya Ramachandran · 2008
We present cache-efficient chip multiprocessor (CMP) algorithms with good speed-up for some widely used dynamic programming algorithms. We consider three types of caching systems for CMPs: D-CMP with a private cache for each core, S-CMP with a single cache shared by all cores, and Multicore, which has private L1 caches and a shared L2 cache. We derive results for three classes of problems: local dependency dynamic programming (LDDP), Gaussian Elimination Paradigm (GEP), and parenthesis problem.
