我在编写一些 C++ AMP 代码时遇到问题。我已经包含了一个样本。它在模拟加速器上运行良好，但在我的硬件（Windows 7、NVIDIA GeForce GTX 660、最新驱动程序）上崩溃了显示驱动程序，但我看不出我的代码有任何问题。
我的代码有问题还是硬件/驱动程序/编译器问题？
#include "stdafx.h"
#include <vector>
#include <iostream>
#include <amp.h>
int _tmain(int argc, _TCHAR* argv[])
{
// Prints "NVIDIA GeForce GTX 660"
concurrency::accelerator_view target_view = concurrency::accelerator().create_view();
std::wcout << target_view.accelerator.description << std::endl;
// lower numbers do not cause the issue
const int x = 2000;
const int y = 30000;
// 1d array for storing result
std::vector<unsigned int> resultVector(y);
Concurrency::array_view<unsigned int, 1> resultsArrayView(resultVector.size(), resultVector);
// 2d array for data for processing
std::vector<unsigned int> dataVector(x * y);
concurrency::array_view<unsigned int, 2> dataArrayView(y, x, dataVector);
parallel_for_each(
// Define the compute domain, which is the set of threads that are created.
resultsArrayView.extent,
// Define the code to run on each thread on the accelerator.
[=](concurrency::index<1> idx) restrict(amp)
{
concurrency::array_view<unsigned int, 1> buffer = dataArrayView[idx[0]];
unsigned int bufferSize = buffer.get_extent().size();
// needs both loops to cause crash
for (unsigned int outer = 0; outer < bufferSize; outer++)
{
for (unsigned int i = 0; i < bufferSize; i++)
{
// works without this line, also if I change to buffer[0] it works?
dataArrayView[idx[0]][0] = 0;
}
}
// works without this line
resultsArrayView[0] = 0;
});
std::cout << "chash on next line" << std::endl;
resultsArrayView.synchronize();
std::cout << "will never reach me" << std::endl;
system("PAUSE");
return 0;
