OpenCL 在英特尔系统上生成错误 -32

Question

我正尝试在 OpenCL 上学习本教程：

https://anteru.net/2012/11/03/2009/

代码如下：

   // http://www.khronos.org/registry/cl/sdk/1.1/docs/man/xhtml/clGetPlatformIDs.html
        cl_uint platformIdCount = 0;
        clGetPlatformIDs(0, nullptr, &platformIdCount);

        if (platformIdCount == 0) {
            std::cerr << "No OpenCL platform found" << std::endl;
            return 1;
        }
        else {
            std::cout << "Found " << platformIdCount << " platform(s)" << std::endl;
        }

        std::vector<cl_platform_id> platformIds(platformIdCount);
        clGetPlatformIDs(platformIdCount, platformIds.data(), nullptr);

        for (cl_uint i = 0; i < platformIdCount; ++i) {
            std::cout << "\t (" << (i + 1) << ") : " << GetPlatformName(platformIds[i]) << std::endl;
        }

        // http://www.khronos.org/registry/cl/sdk/1.1/docs/man/xhtml/clGetDeviceIDs.html
        cl_uint deviceIdCount = 0;
        clGetDeviceIDs(platformIds[0], CL_DEVICE_TYPE_ALL, 0, nullptr,
            &deviceIdCount);

        if (deviceIdCount == 0) {
            std::cerr << "No OpenCL devices found" << std::endl;
            return 1;
        }
        else {
            std::cout << "Found " << deviceIdCount << " device(s)" << std::endl;
        }

        std::vector<cl_device_id> deviceIds(deviceIdCount);
        clGetDeviceIDs(platformIds[0], CL_DEVICE_TYPE_ALL, deviceIdCount,
            deviceIds.data(), nullptr);

        for (cl_uint i = 0; i < deviceIdCount; ++i) {
            std::cout << "\t (" << (i + 1) << ") : " << GetDeviceName(deviceIds[i]) << std::endl;
        }

        // http://www.khronos.org/registry/cl/sdk/1.1/docs/man/xhtml/clCreateContext.html
        const cl_context_properties contextProperties[] =
        {
            CL_CONTEXT_PLATFORM, reinterpret_cast<cl_context_properties> (platformIds[0]),
            0, 0
        };

        cl_int error = CL_SUCCESS;
        cl_context context = clCreateContext(contextProperties, deviceIdCount,
            deviceIds.data(), nullptr, nullptr, &error);
        CheckError(error);

我运行它在 Intel i5 笔记本电脑上。输出如下：

Found 2 platform(s)
         (1) : Experimental OpenCL 2.0 CPU Only Platform
         (2) : Intel(R) OpenCL
Found 1 device(s)
         (1) :        Intel(R) Core(TM) i5-3210M CPU @ 2.50GHz

错误代码为-32

我在 windows 7 计算机上使用 visual studio 2013。

我该如何解决？

Answer 1

有时英特尔 OpenCL SDK 没有所有驱动程序，尤其是对于较旧的 Xeon 和 iCore 设备。英特尔确实为这些设备提供了额外的运行时安装程序，只是没有使用 SDK。

只需 Google：英特尔 OpenCL 运行时或 try this link（截至 2-2-2015 有效）：
