ArrayFire

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.

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

Example

#include <arrayfire.h>
#include <cstdio>

using namespace af;

int main(int argc, char *argv[])
{
    try {


        // Select a device and display arrayfire info
        int device = argc > 1 ? atoi(argv[1]) : 0;
        af::setDevice(device);
        af::info();

        printf("Create a 5-by-3 matrix of random floats on the GPU\n");
        array A = randu(5,3, f32);
        af_print(A);

        printf("Element-wise arithmetic\n");
        array B = sin(A) + 1.5;
        af_print(B);

        printf("Negate the first three elements of second column\n");
        B(seq(0, 2), 1) = B(seq(0, 2), 1) * -1;
        af_print(B);

        printf("Fourier transform the result\n");
        array C = fft(B);
        af_print(C);

        printf("Grab last row\n");
        array c = C.row(end);
        af_print(c);

        printf("Create 2-by-3 matrix from host data\n");
        float d[] = { 1, 2, 3, 4, 5, 6 };
        array D(2, 3, d, af::afHost);
        af_print(D);

        printf("Copy last column onto first\n");
        D.col(0) = D.col(end);
        af_print(D);

        // Sort A
        printf("Sort A and print sorted array and corresponding indices\n");
        array vals, inds;
        sort(vals, inds, A);
        af_print(vals);
        af_print(inds);

    } catch (af::exception& e) {
