#include <vector>
#include <string>
using std::cout; using std::endl;
using std::vector;
using std::string;

int main(void)
{
    // query the number of platforms available to us
    vector<cl::Platform> platforms;
    cl::Platform::get(&platforms);

    // pick the first platform from the list
    auto platform = platforms.front();

    // query the number of devices available to us
    vector<cl::Device> devices;
    platform.getDevices(CL_DEVICE_TYPE_ALL, &devices);

    // pick the first device from the list
    auto device = devices.front();

    // get the name of the vendor
    string vendor = device.getInfo<CL_DEVICE_VENDOR>();

    cout << vendor << endl;

    return 0;
