G3 is built as a programming framework for Graph Neural Network (GNN) applications that supports graph related operations natively and leverages on the computation power of Graphics Processing Units (GPU). It is named G3, which stands for Graph processing system but tailored for GNN processing on GPUs. The values of G3 can be summarized as follow:
- G3 thrives to fundamentally enhance the performance of GNN applications by incorporating graph oriented operators at the low level.
- G3 provides a set of existing basic modules that can be stacked up to build up user-customized GNN architectures.
- G3 provides flexible C++ based APIs such that developers are able to define and implement their own GNN layers when such layers do not exist in our system.
- G3 frees the programmers from low level GPU thread management and memory management concerns, which is usually daunting and injects numerous unnoticeable bugs into the system.
- G3 automatically applies graph-centric optimizations on the GNN architectures during run time.
We have done some preliminary studies to show how such system can be used to build Graph Convolutional Network (GCN) , the state of the art in various GNN models, and how our implementation exceeds the performances of Tensorflow implementation (the original implementation) as well as PyTorch implementation by a significant margin. Details are here.
G3 is built based on Gunrock, a CUDA library for graph-processing designed specifically for the GPU. For more details, see Gunrock's Github repo. Most of the code is reused from Gunrock's code base. G3 added these components to Gunrock to efficiently support GNN training 1) GCN App and 2) GCN Example.
CMake >= 3.10
G++ >= 7.5
CUDA >= 9.0
git clone --recursive https://github.com/Xtra-Computing/G3.git
cd G3
mkdir build
cd build
cmake ..
make -j
After that, you can run the example GCN application:
cd bin
./gcn
