This is the reference implementation for the GARDENIA Benchmark Suite. It is designed to be a portable high-performance baseline for desgining next-generation accelerators. It uses CUDA, OpenCL and OpenMP for parallelism. The details of the benchmark can be found in the specification.

The GARDENIA Benchmark Suite is an extented version of the GAP Benchmark Suite which is intended to help graph processing research by standardizing evaluations. The benchmark provides a baseline implementation which incorporates state-of-the-art optimization techniques proposed for modern accelerators, such as GPUs and MICs. These baseline implementations are representative of state-of-the-art performance, and thus new contributions should outperform them to demonstrate an improvement. The code infrastructure is ported from GAPBS and Lonstargpu by the ISS group at the University of Texas. To run the benchmarks on the GPGPU-Sim simulator, please use the revised GPGPU-Sim version and we highly recommend you to use CUDA-5.5 for the compatibility issue. Note that in the code, 'm' is the number of vertices, and 'nnz' is the number of edges. Graphs are stored as the CSR format in memory. CSR is represented by two auxiliary data structures: 'row_offsets' and 'column_indices'. You will need to download CUB.

Kernels Included

• Betweenness Centrality (BC) - Brandes
• Breadth-First Search (BFS) - direction optimizing
• Connected Components (CC) - Afforest & Shiloach-Vishkin
• Minimum Spanning Tree (MST) -
• PageRank (PR) - iterative method in pull direction
• Strongly Connected Components (SCC) - Forward-Backward-Trim
• Stochastic Gradient Descent (SGD) -
• Sparse Matrix-Vector Multiplication (SpMV)
• Single-Source Shortest Paths (SSSP) - delta stepping
• Symmetric Gauss-seidel Smoother (SymGS) -
• Triangle Counting (TC) - Order invariant with possible relabelling
• Vertex Coloring (VC) - Gebremedhin and Manne

Quick Start

Setup CUB library:

$ git submodule update --init --recursive

Build the project (you will need to install gcc and nvcc first):

$ make

Or go to each sub-directory, e.g. bfs, and then

$ make

Download datasets from the UFSMC or SNAP website:

$ wget https://www.cise.ufl.edu/research/sparse/MM/SNAP/soc-LiveJournal1.tar.gz

Decompress the dataset file and put it in the 'datasets' sub-directory:

$ tar zxvf soc-LiveJournal1.tar.gz

Run BFS on a directed graph starting from vertex 0:

$ cd bin
$ ./bfs_linear_base ../datasets/soc-LiveJournal1.mtx 0 1

To run on CPU or Intel Xeon Phi coprocessor, set the following environment variable:

$ export OMP_NUM_THREADS=[ number of cores in system ]

Graph Loading

The graph loading infrastructure understands the following formats:

• .mtx Matrix Market format
• .gr 9th DIMACS Implementation Challenge format
• .graph Metis format (used in 10th DIMACS Implementation Challenge)
