******************************************************************************** * THIS IS A WORK IN PROGRESS. DO NOT USE THIS FOR PRODUCTION WORK * ******************************************************************************** VertexAPI2 ========== Introduction ------------ VertexAPI2 is a CUDA/C++ library for developing large graph analytics. The goal is to hide the complexity of GPU programming while presenting a simple API. VertexAPI2 uses the Gather-Apply-Scatter model used in GraphLab [cite]. VertexAPI2 is a work in progress. At this time we have a few working examples like breadth first search, single source shortest paths and Page rank. The API changes constantly as we evaluate and understand the best way to develop further. If you are interested in using our project in your own work, please send an email to the authors. Known Issues ------------ The moderngpu library uses only one dimensional grids and consequently this code will fail on Fermi cards for graphs with more than 8.3 million edges. Installation ------------ The API is available as header files in the vertexAPI2 directory. To build the example programs and a few utility objects, run 'make' in the vertexAPI2 directory. Notes: - A working installation of CUDA >= 5.0 is required. - The moderngpu library should be available alongside the vertexAPI2 directory (mgpu patches to be made public on our repo?) Building GraphLab regressions ----------------------------- To perform a regression test against GraphLab, a working installation of GraphLab is required. Edit the file vertexAPI2/PowerGraphReferenceImplementations/Makefile to reflect the location of GraphLab on your system and then run 'make' in the PowerGraphReferenceImplementations directory. To download some test graphs, run 'make' in the test-graphs directory. Finally run 'make' in the regressions directory. At the end you can run './report.py' to summarize the timing comparisons between GraphLab and vertexAPI2.

Is this part of the cuda toolkit? I am using cuda 6.0
