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

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.
You can install the ArrayFire library from one of the following ways:
Execute one of our official binary installers for Linux, OSX, and Windows platforms.
Build from source by following instructions on our wiki.
The following examples are simplified versions of
helloworld.cpp
and
conway_pretty.cpp,
respectively. For more code examples, visit the
examples/
directory.
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);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
}
