From the post:
MapGraph is Massively Parallel Graph processing on GPUs. (Previously known as “MPGraph”).
- The MapGraph API makes it easy to develop high performance graph analytics on GPUs. The API is based on the Gather-Apply-Scatter (GAS) model as used in GraphLab. To deliver high performance computation and efficiently utilize the high memory bandwidth of GPUs, MapGraph’s CUDA kernels use multiple sophisticated strategies, such as vertex-degree-dependent dynamic parallelism granularity and frontier compaction.
- New algorithms can be implemented in a few hours that fully exploit the data-level parallelism of the GPU and offer throughput of up to 3 billion traversed edges per second on a single GPU.
- Preliminary results for the multi-GPU version of MapGraph have traversal rates of nearly 30 GTEPS (30 billion traversed edges per second) on a scale-free random graph with 4.3 billion directed edges using a 64 GPU cluster. See the multi-GPU paper referenced below for details.
- The MapGraph API also comes in a CPU-only version that is currently packaged and distributed with the bigdata open-source graph database. GAS programs operate over the graph data loaded into the database and are accessed via either a Java API or a SPARQL 1.1 Service Call . Packaging the GPU version inside bigdata will be in a future release.

You do have to wonder when the folks at Systap sleep. 😉 This is the same group that produced BlazeGraph, recently adopted by WikiData. Granting WikiData only has 13.6 million data items as of today but it isn’t “small” data.
