ArrayFire是一個用于并行計算的高性能軟件庫，擁有易于使用的API。其基于陣列的功能設置，使并行編程簡單。

ArrayFire的多個后端（CUDA，OpenCL和本地CPU），使其獨立于平臺和高便攜性。

在ArrayFire幾行代碼就可以取代數十個并行計算代碼行，為您節省寶貴的時間和降低開發成本。

示例：

#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) {
    fprintf(stderr, "%s\n", e.what());
    throw;
}
