BFS-4K Documentation Page

January, 2014

BFS-4K is a parallel implementation of vreadth-first search (BFS) for GPUs that exploits the more advanced features of GPU-based platforms (i.e., NVIDIA Kepler). It implements different strategies to deal with the potential workload imbalance and thread divergence caused by any actual graph non-homogeneity.

BFS-4K is developed in C for CUDA under GNU\Linux. It requires NVIDIA GPU devices with compute capability 3.5 (Kepler GK110 architectures).

See the related scientific article for more details.
