### Install development tools 

    $ sudo apt-get install build-essential

    $ sudo apt-get install git

### Install Vortex codebase

    $ git clone --recursive https://github.com/vortexgpgpu/vortex.git

    $ cd Vortex

### Install prebuilt toolchain

    By default, the toolchain will install to /opt folder which requires sudo access. 

    You can install the toolchain to a different location of your choice by setting TOOLDIR (e.g. export TOOLDIR=$HOME/tools).

    $ export TOOLDIR=/opt

    $ ./ci/toolchain_install.sh --all

    $ source ./ci/toolchain_env.sh

### Build Vortex sources

    $ make -s

### Quick demo running vecadd OpenCL kernel on 2 cores

    $ ./ci/blackbox.sh --cores=2 --app=vecadd
