Machine Requirements

We run graph4code on an Intel VM with 64 cores, 512GB of RAM and 2TB of disk.

Loading Graph4Code

This script downloads and loads Graph4Code quad files in Apache Jena. The following scripts are tested on Linux Ubuntu with Java (openjdk version “1.8.0_252”) and Ruby “ruby 2.3.1p112” installed.

The main script (shown below) perform the following steps:

• Clone this repository
• Download Graph4Code (download_graph.sh)
• Build Jena DB using the downloaded files (build_graph.sh)
• Start Jena Fuseki for querying the loaded graph (serve_graph.sh).

#!/bin/bash

Docker

Alternatively, we also provide a docker file for creating a docker image with the graph database ready to use.

The required steps are as follows:

• Clone this repo and go to script folder:

     git clone https://github.com/wala/graph4code.git
     cd graph4code/scripts/
  
  

• Download graph4code quads

     mkdir grgraph4code_quads
     ./download_graph.sh ./graph4code_quads
  

• Build the base docker image

     docker build -t graph4code_base -f dockerfile_base .
     docker build -t graph4code_build -f dockerfile_build .
     docker build -t graph4code_serve -f dockerfile_serve .
  

• Create directory where Jena db will be created ``` mkdir graph4code_db/
• Run the build docker image and mount Jena db directory:

     docker run --rm -it -v `pwd`/graph4code_quads/:/graph4code_quads/ -v `pwd`/graph4code_db/:/graph4code_db/ graph4code_build
  

• Now the db is ready, run the serve docker image and expose Jena default port.

     docker run --rm -it --expose 3030 -v `pwd`/graph4code_db/:/graph4code_db/ graph4code_serve
  

• This will start a background process for Jena Fuseki and should be accessible via http://localhost:3030/.
