Qt и AMP

QT, AMP, многопоточность

Здравствуйте.

Как в QT, используя технологию AMP прописать многопоточное использование всех CPU и GPU lдля расчета function(idx); в разных потоках:
main.cpp:
MainWindow w;
for ( int idx = 0; idx <500000; idx ++)  
{  
  w.StrategyCod(idx);  
}

Пока используя технологию QtConcurrent могу использовать только все CPU, и выглядит оно так:

MainWindow w;
QVector<double> Perebor; //перебор первого значения стратегии
for (double i=5;i<1000;i=i+3)
{
    Perebor.append(i);
}
 QFuture<void> Perebor2 = QtConcurrent::map(Perebor,[&w](const double& d){ w.StrategyCod(d); });  //просчет стратегии в нескольхих потоках

Для GPU ищите информацию по запросу opencl tutorial c++, к Qt это никакого отношения не имеет.

    Я скачал opencl с сайта интел, но он у меня не работает. И Cuda от нвидеа не работает почему то.  Но у меня есть висуал студиа. Почему не сработает АМР, если взять нужные библиотеки из висуал студио?
