Parallel bfs algorithm

WebNov 16, 2024 · The problem here is that the entire body of dfs () is one critical section, which means that even if there are 1000 recursive calls in parallel, they will execute one after another sequentially and not in parallel. It will even be slower than the sequential version because of the constant cache invalidation and the added OpenMP overhead. WebParallel algorithms for BFS date back to nearly three decades [31,32]. The classical parallel random access ma-chine (PRAM) approach to BFS is a straightforward exten …
