Dijkstra gpu

WebParallel implementation of proposed modified Dijkstra’s algorithm gives a two to three times speed increase over a parallel Dijkstra’s algorithm on a GPU-based machine for complete and dense graphs. The proposed algorithm has minimized the number of edges relaxed by one parallel thread at any iteration of parallel Dijkstra’s algorithm ... WebThe Dijkstra Single-Source algorithm computes the shortest paths between a source node and all nodes reachable from that node. To compute the shortest path between a source and a target node, Dijkstra Source-Target can be used. The GDS implementation is based on the original description and uses a binary heap as priority queue.
