使用 Optimus 的笔记本电脑上的 CUDA 出现问题
我已在配备 GeForce GT 325M (Win7 x64) 的 ASUS N61J 上安装了 CUDA 工具包 v4.0 RC2。 设法将 Cuda 与 Visual Studio 2010 集成。
我尝试运行从这里窃取的示例代码 http://llpanorama.wordpress.com/2008/05/21/my-first-cuda-program/。该程序编译并运行,但 CUDA 返回错误:
cuda driver version is insufficient for cuda runtime version
好的,我做了一些谷歌搜索并决定安装最新的开发人员驱动程序。无论如何都没有帮助 - 同样的错误=\
也许程序没有“看到”我有一个与 CUDA 兼容的硬件?我需要你的帮助! =)
I've installed CUDA toolkit v4.0 RC2 on my ASUS N61J with GeForce GT 325M (Win7 x64).
Managed to integrate Cuda with Visual Studio 2010.
I try to run an example code stolen from here http://llpanorama.wordpress.com/2008/05/21/my-first-cuda-program/. The program compiles and runs but CUDA returns error:
cuda driver version is insufficient for cuda runtime version
Ok, i do some googling and decide to install the latest developer driver. Doesn't help anyway - the same error =\
Maybe the program doesn't "see" that i have a CUDA-compatible hardware? I need your help! =)

最新驱动程序和最新 CUDA 工具包的安装正确。否则你可能会遇到不一致的情况。
对于移动 GPU,还有至少 256MB 显存的额外要求 (http://www.nvidia.com/object/cuda_gpus.html)。您可以使用GPU-Z<等工具检查您拥有的图形内存量/强>。
The installation of the latest drivers together with the latest CUDA toolkit is correct. Otherwise you might get inconsistencies.
For the mobile GPUs there is an additional requirement of Minimum 256MB of graphics memory (http://www.nvidia.com/object/cuda_gpus.html). You can check the amount of graphics memory you have by using a tool like GPU-Z.
我还没有在 Visual Studio 上尝试过 CUDA。
我在 Linux 上也有同样的问题。
问题可能出在 Optimus 技术上,该技术会关闭 GPU 以降低功耗。
Linux 不支持 Optimus 技术。
但它应该可以在 Windows 上运行。并且可以选择为特定应用程序打开 GPU。打开 VS 并重试并在 NVidia 论坛上查看更多详细信息。
GT325M 正式支持 Cuda http://www.nvidia.com/object/product_geforce_gt_325m_us.html
I haven't tried CUDA on Visual studio yet.
I have the same problem on Linux.
The problem can be Optimus technology, which switches off the GPU to reduce power consumption.
Optimus technology is not supported on Linux.
But it should work on Windows. And there is an option to switch on GPU for specific applications. Turn it on for VS and try again and Check more details on NVidia forums.
Cuda is officially supported on GT325M http://www.nvidia.com/object/product_geforce_gt_325m_us.html
