This repository provides the Hornet data structure and algorithms on sparse graphs and matrices.
The document is organized as follows:
- Requirements
- Quick start
- Supported graph formats
- Code Documentation
- Notes
- Reporting bugs and contributing
- Publications
- Hornet Developers
- License
- Nvidia Modern GPU (compute capability ≥ 6.0): Pascal and Volta architectures.
- CUDA toolkit 9 or greater.
- GCC or Clang host compiler with support for C++14. Note, the compiler must be compatible with the related CUDA toolkit version. For more information see CUDA Installation Guide.
- CMake v3.8 or greater.
- 64-bit Operating System (Ubuntu 16.04 or above suggested).
The following basic steps are required to build and execute Hornet:
git clone --recursive https://github.com/hornet-gt/hornet
export CUDACXX=<path_to_CUDA_nvcc_compiler>
cd hornet/build
cmake ..
make -j
To build HornetsNest (algorithms directory):
cd hornetsnest/build
cmake ..
make -j
By default, the CUDA compiler nvcc
uses gcc/g++
found in the current
execution search path as host compiler
(cc --version
to get the default compiler on the actual system).
To force a different host compiler for compiling C++ files (*.cpp
)
you need to set the following environment variables:
CC=<path_to_host_C_compiler>
CXX=<path_to_host_C++_compiler>
Note: host .cpp
compiler and host side .cu
compiler may be different.
The host side compiler must be compatible with the current CUDA Toolkit
version installed on the system
(see CUDA Installation Guide).
The syntax and the input parameters of Hornet are explained in detail in
docs/Syntax.txt
. They can also be found by typing ./HornetTest --help
.
Hornet supports the following graph input formats:
- Market (.mtx), The University of Florida Sparse Matrix Collection
- Metis (.graph), 10th DIMACS Implementation Challenge
- SNAP (.txt), Stanford Network Analysis Project
- Dimacs9th (.gr), 9th DIMACS Implementation Challenge
- The Koblenz Network Collection (out.< name >), The Koblenz Network Collection
- Network Data Repository (.edges), Network Data Repository
- Binary (.bin)
Hornet directly deduces the graph structure (directed/undirected) from the input file header.
Hornet allows reading the input graph by using a fixed binary format to speed up the file loading.
The binary file is generated by Hornet with the --binary
command line option.
The code documentation is located in the docs
directory (doxygen html format).
- Hornet has been checked with the following tools to ensure the code quality:
- clang++ v4.0: warnings
- clang-tidy: warnings and code styles
- Hornet has been tested with the following tools: (see
CodeCheck
)
If you find any bugs please report them by using the repository (github issues panel). We are also ready to engage in improving and extending the framework if you request new features.
