WebSep 28, 2012 · Graph is widely used in many areas. Breadth-First Search (BFS), a key subroutine for many graph analysis algorithms, has become the primary benchmark for Graph500 ranking. Due to the high communication cost of BFS, multi-socket nodes with large memory capacity (NUMA) are supposed to reduce network pressure. However, the … Web3MPI-only BFS Algorithm and Analysis In this section we first introduce an MPI-only BFS algo-rithm in the Graph 500 benchmark, then perform some experimental analyses to …
Webgorithm (GTEPS mean of 10 runs on a Graph500 graph and change relative to the previous row). 3. BFS ALGORITHM DESCRIPTION We use a level-synchronized algorithm for BFS. The al-gorithm has two loops: the outer loop iterates over frontier queues and the inner loop iterates over each of a vertex’s out- WebOne hundred to 750 concurrent breadth-first searches (BFS) all achieve end-to-end speed-ups of 81% to 97% over one-at-a-time queries on a graph with 522M edges. Comparing to RedisGraph running on a large Intel-based server, the Pathfinder achieves a 19 × \times × speed-up running 128 BFS queries concurrently. The Pathfinder also efficiently ...
