ArrayFire is a general-purpose library that simplifies the process of developing software that targets parallel and massively-parallel architectures including CPUs, GPUs, and other hardware acceleration devices.
Several of ArrayFire's benefits include:
- Easy to use, stable, well-documented API
- Rigorously tested for performance and accuracy
- Commercially friendly open-source licensing
- Commercial support from ArrayFire
- Read about more benefits on arrayfire.com
ArrayFire provides software developers with a high-level
abstraction of data which resides on the accelerator, the af::array object.
Developers write code which performs operations on ArrayFire arrays which, in turn,
are automatically translated into near-optimal kernels that execute on the computational
device.
ArrayFire is successfully used on devices ranging from low-power mobile phones to high-power GPU-enabled supercomputers. ArrayFire runs on CPUs from all major vendors (Intel, AMD, ARM), GPUs from the prominent manufacturers (NVIDIA, AMD, and Qualcomm), as well as a variety of other accelerator devices on Windows, Mac, and Linux.
Installation
You can install the ArrayFire library from one of the following ways:
Official installers

Build from source
Build from source by following instructions on our wiki.
Examples
The following examples are simplified versions of
helloworld.cpp
and
conway_pretty.cpp,
respectively. For more code examples, visit the
examples/
directory.
Hello, world!
array A = randu(5, 3, f32); // Create 5x3 matrix of random floats on the GPU
array B = sin(A) + 1.5; // Element-wise arithmetic
array C = fft(B); // Fourier transform the result
float d[] = { 1, 2, 3, 4, 5, 6 };
array D(2, 3, d, afHost); // Create 2x3 matrix from host data
D.col(0) = D.col(end); // Copy last column onto first
array vals, inds;
sort(vals, inds, A); // Sort A and print sorted array and corresponding indices
af_print(vals);
af_print(inds);Conway's Game of Life
Visit the Wikipedia page for a description of Conway's Game of Life.
static const float h_kernel[] = {1, 1, 1, 1, 0, 1, 1, 1, 1};
static const array kernel(3, 3, h_kernel, afHost);
array state = (randu(128, 128, f32) > 0.5).as(f32); // Generate starting state
Window myWindow(256, 256);
while(!myWindow.close()) {
array nHood = convolve(state, kernel); // Obtain neighbors
array C0 = (nHood == 2); // Generate conditions for life
array C1 = (nHood == 3);
state = state * C0 + C1; // Update state
myWindow.image(state); // Display
}
