Near-Far Pile Algorithm for GPU

This is a naive implementation of the Near-Far Pile Single Source Shortest Path Algorithm by Davidson et al.

Requirements

Build

Using Docker

  1. Install Docker and NVIDIA for Docker
  2. Build image docker build . --pull --rm f "Dockerfile" -t naive-near-far-gpu:latest
  3. Image will automatically download libraries and compile the software

Locally

  1. Make sure CUDA 7.5 is installed
  2. Run the build script sh build.sh
  3. The build script downloads CUSP

Running

  • Command: ./main `[m|d]` <file>
  • Example ./main m graph.mtx
  • First argument: file type. m for Matrix Market *.mtx files, d for Dimacs
  • Second argument: path to file

Docker

  1. Create a local folder to put your graphs
  2. Set this local folder as a volume in Docker
  3. Run command
docker run -v <local-path-to-graphs>:/<docker-path> --name near-far --gpus all near-far-pile:latest ./main `[m|d]` <docker-path>/<file>
  1. Copy "distance.mtx" file from Docker to local folder: docker cp near-far:distance.mtx .
