Breadth-First Graph Search Uses 2D Domain Decomposition – 400 GTEPS on 4096 GPUs
Parallel Breadth-First Search is a standard benchmark and the basis of many other graph algorithms. The challenge lies in partitioning the graph across multiple nodes in a cluster while avoiding load-imbalance and communications delays. The authors of the paper, "Parallel Breadth First Search on the Kepler Architecture" utilize an interesting 2D decomposition of the graph … [Read more...]
