CUDA - 无效的设备功能，如何知道[架构，代码]? [英] CUDA - invalid device function, how to know [architecture, code]?

问题描述

在 VS 社区中创建 CUDA 项目时运行默认生成的内核时出现以下错误:

I am getting the following error when running the default generated kernel when creating a CUDA project in VS Community:

addKernel launch failed: invalid device function
addWithCuda failed!

我搜索了如何解决它，发现必须更改Project->Properties->CUDA C/C++->Device->Code Generation(默认值[architecture, code] 是 compute_20,sm_20)，但我找不到我的显卡 (GeForce 8400 GS) 所需的值

I searched for how to solve it, and found out that have to change the Project->Properties->CUDA C/C++->Device->Code Generation(default values for [architecture, code] are compute_20,sm_20), but I couldn't find the values needed for my graphic card (GeForce 8400 GS)

网上是否有[架构，代码]的列表，或者是否可以通过任何命令获取它们?

Is there any list on the net for the [architecture, code] or is it possible to get them by any command?

推荐答案

compute_XX 和 sm_XX 中的数值是 CUDA 设备的计算能力 (CC).

The numeric value in compute_XX and sm_XX are the Compute Capability (CC) for your CUDA device.

您可以查找此链接 http://en.wikipedia.org/wiki/CUDA#Supported_GPUs 获取(可能不完整)GPU 列表和相应的 CC.

You can lookup this link http://en.wikipedia.org/wiki/CUDA#Supported_GPUs for a (maybe not complete) list of GPUs and there corresponding CC.

您相当旧的 8400 GS(当我没记错的时候)拥有支持 CC 1.1 的 G86 芯片.

Your quite old 8400 GS (when I remember correctly) hosts a G86 chip which supports CC 1.1.

所以你要改成compute_11,sm_11
