HD处理器图形(HD4000)无法作为Intel OpenCL SDK中的设备加载 [英] HD Processor Graphics (HD4000) failed to load as a device in Intel OpenCL SDK

问题描述

我正在将i7-3770K Ivy Bridge与HD 4000一起使用，并且已经安装了最新的驱动程序和最新的

I'm using i7-3770K Ivy Bridge with HD 4000, and I've installed the latest drivers and the newest OpenCL SDK.

当尝试使用CPU运行代码示例时，它可以正常工作.但是，当我将'-g'参数设置为与正在处理的图形一起运行时，找不到该设备，因此它以代码-1退出(这很可能是由于未能创建CL上下文所致).

When tried to run the code samples with CPU, it works just fine. However, when I set the '-g' parameter to run with the processing graphics, the device cannot be found hence it exited with code -1 (which is likely caused by failing to create a CL context).

SimpleOptimization，GodRays和所有支持英特尔处理器图形的代码无法与HD4000一起运行.

SimpleOptimization, GodRays, and all codes that support Intel Processor Graphics failed to run with the HD4000.

我正在使用Windows 7 64位MSVS VC ++ 2008 Express Edition.

I am using Windows 7 64-bit, MSVS VC++ 2008 express edition.

GPU Caps Viewer 也无法将Intel HD Graphics检测为Intel OpenCL设备.

GPU Caps Viewer also could not detect Intel HD Graphics as the Intel OpenCL device.

此外，当我运行 DirectX SDK 代码示例中，可以完美地检测到Intel HD 4000，并且可以在HD Graphics上正常运行代码.

In addition, when I run DirectX SDK code samples, the Intel HD 4000 was detected perfectly and it run the code just fine with the HD Graphics.

我的系统上还有一个nvidia卡，可以作为图形驱动程序运行.

And I also have an nvidia card on my system which runs as the graphical driver.

有什么主意我该如何解决这个问题?

Any idea how do I solve this problem?

推荐答案

我已经根据Intel在SE中的声明设法解决了我的问题.现在，HD Graphics可以完美地作为OpenCL设备运行.

I've managed to solve my problem based on a statement of SE in Intel. Now the HD Graphics run perfect as an OpenCL device.

"I also have an nvidia card on my system which runs as the graphical driver."

Maxim Shevtsov(Intel):这可能是实际的根源-原因. 当前处理器图形OCL设备在 无头"配置(未插入监视器).

Maxim Shevtsov (Intel): Likely this is the actual root-cause. Currently Processor Graphics OCL device in unavailable in the "headless" configuration (without a monitor plugged in).

这是英特尔论坛中的问答环节，我希望这对遇到此问题的人有用:

And this is the Q&A in Intel forum and the answer, I hope this is useful for someone who encounters this problem:
