ArrayFire is a high performance software library for parallel computing with an easy-to-use API. Its array based function set makes parallel programming simple.

ArrayFire's multiple backends (CUDA, OpenCL and native CPU) make it platform independent and highly portable. ArrayFire provides visualization capabilities using our OpenGL-based, high performance visualization library.

A few lines of code in ArrayFire can replace dozens of lines of parallel computing code, saving you valuable time and lowering development costs.

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
}
