ArrayFire Graph is an out-of-core dynamic graph library that runs on NVIDIA GPUs. It enables users to create and update graphs at a very high rate. AF Graph has a number of high-performance graph analytic algorithms that can be run on the dynamic data. Dynamic graphs allow users to provide incremental edge updates instead of rebuilding the whole graph. AF Graph's out-of-core support can handle graphs that cannot fit in GPU memory and can handle billions of edges.
