ArrayFire Binary Installation Instructions

Installing ArrayFire couldn't be easier. We ship installers for Windows, OSX, and Linux. Although you could build ArrayFire from source, we suggest using our pre-compiled binaries as they include the Intel Math Kernel Library to accelerate linear algebra functions.

Please note that although our download page requires a valid login, registration is free and downloading ArrayFire is also free. We request your contact information so that we may notify you of software updates and occasionally collect user feedback about our library.

In general, the installation process for ArrayFire looks like this:

  1. Install prerequisites
  2. Download the ArrayFire installer for your operating system
  3. Install ArrayFire
  4. Test the installation
  5. Where to go for help?

Below you will find instructions for:

Windows

If you wish to use CUDA or OpenCL please ensure that you have also installed support for these technologies from your video card vendor's website.

Next, download and run the ArrayFire installer. After installation, you'll need to add ArrayFire to the path for all users:

  1. Open Advanced System Settings:
    • Windows 8: Move the Mouse pointer to the bottom right corner of the screen, Right click, choose System. Then click "Advanced System Settings"
    • Windows 7: Open the Start Menu and Right Click on "Computer". Then choose Properties and click "Advanced System Settings"
  2. In Advanced System Settings window, click on Advanced tab
  3. Click on Environment Variables, then under System Variables, find PATH, and click on it.
  4. In edit mode, append AF_PATH%/lib. Make sure to separate AF_PATH%/lib from any existing content using a semicolon (e.g. EXISTING_PATHS;AF_PATH%/lib;). Other software may function incorrectly if this is not the case.

Finally, verify that the path addition worked correctly. You can do this by:

  1. Open Visual Studio 2013. Open the HelloWorld solution which is located at AF_PATH%/examples/helloworld/helloworld.exe.
  2. Build and run the helloworld example. Use the "Solution Platform" drop-down to select from the CPU, CUDA, or OpenCL backends ArrayFire provides.

Linux

Debian 8

First, install the prerequisite packages:

# Install prerequisite packages:
apt-get install libglfw3-dev cmake

# Enable GPU support (OpenCL):
apt-get install ocl-icd-libopencl1

If you wish to use CUDA, download and install the latest version.

Next, download the ArrayFire installer for your system. After you have the file, run the installer:

./arrayfire_*_Linux_x86_64.sh --exclude-subdir --prefix=/usr/local

RedHat, Fedora, and CentOS

First, install the prerequisite packages:

# Install prerequiste packages
yum install glfw cmake

NOTE: On CentOS and Redhat, the glfw package is outdated and you will need to compile it from source. Follow these instructions for more information on how to build and install GFLW.

If you wish to use CUDA, download and install the latest version.

Next, download the ArrayFire installer for your system. After you have the file, run the installer:

./arrayfire_*_Linux_x86_64.sh --exclude-subdir --prefix=/usr/local

Ubuntu 14.04 and later

First, install the prerequisite packages:

Ubuntu 16.04

# Install prerequisite packages:
sudo apt-get install libglfw3-dev cmake

Ubuntu 14.04

# Install prerequisite packages:
sudo apt-get install cmake

Ubuntu 14.04 does not include the libglfw3-dev package in its repositories. In order to install, you can either:

  1. Build the library from source by following these instructions, or
  2. Install the library from a PPA as follows:

    sudo apt-add-repository ppa:keithw/glfw3 sudo apt-get update sudo apt-get install glfw3

At this point, the installation should proceed identically for Ubuntu 14.04 and newer.

If your system has a CUDA GPU, we suggest downloading the latest drivers from NVIDIA in the form of a Debian package and installing using the package manager. At present, CUDA downloads can be found on the NVIDIA CUDA download page. Follow NVIDIA's instructions for getting CUDA set up.

If you wish to use OpenCL, simply install the OpenCL ICD loader along with any drivers required for your hardware.

# Enable GPU support (OpenCL):
apt-get install ocl-icd-libopencl1

Special instructions for Tegra X1

The ArrayFire binary installer for Tegra X1 requires at least JetPack 2.3 or L4T 24.2 for Jetson TX1. This includes Ubuntu 16.04, CUDA 8.0 etc.

You will also want to install the following packages when using ArrayFire on the Tegra X1:

sudo apt-get install libopenblas-dev liblapacke-dev

Special instructions for Tegra K1

You will also want to install the following packages when using ArrayFire on the Tegra K1:

sudo apt-get install libatlas3gf-base libatlas-dev libfftw3-dev liblapacke-dev

Finally, download ArrayFire for your system. After you have the file, run the installer using:

./arrayfire_*_Linux_x86_64.sh --exclude-subdir --prefix=/usr/local

Mac OSX

On OSX there are several dependencies that are not integrated into the operating system. The ArrayFire installer automatically satisfies these dependencies using Homebrew. If you don't have Homebrew installed on your system, the ArrayFire installer will ask you do to so.

Simply download the ArrayFire installer and double-click it to carry out the installation.

ArrayFire can also be installed through Homebrew directly using brew install arrayfire; however, it will not include MKL acceleration of linear algebra functions.

Testing installation

Test ArrayFire after the installation process by building the example programs as follows:

cp -r /usr/local/share/ArrayFire/examples .
cd examples
mkdir build
cd build
cmake ..
make
