错误:标识符“atomicAdd"；在visual studio 2010 & 下未定义带有 Fermi GPU 的 cuda 4.2 [英] error : identifier "atomicAdd" is undefined under visual studio 2010 & cuda 4.2 with Fermi GPU

问题描述

我试图在 Visual Studio 2010 下使用 CUDA 4.2 编译一些 CUDA 代码(我使用 Parallel Nsight 2.2 创建了这个 CUDA 项目)，但我遇到了一个原子问题错误:标识符atomicAdd"未定义"，我仍然查了几个论坛都解决不了.

I was trying to compile some CUDA codes under visual studio 2010 with CUDA 4.2 (I created this CUDA project using Parallel Nsight 2.2), but I encountered an atomic problem "error : identifier "atomicAdd" is undefined", which I still can't solve after checking several forums.

所以我尝试从 CUDA SDK 示例中获取一些信息.首先，我在 CUDA SDK 中运行了 simpleAtomicIntrinsics 示例，它通过了测试.然后，我将此示例中的所有文件复制到 Visual Studio 2010 中的一个新的 CUDA 4.2 项目中并编译它们，结果如下.

So I tried to get some information from CUDA SDK Samples. First, I ran the simpleAtomicIntrinsics sample in CUDA SDK, which passed its test. Then, I copied all the files in this sample to a new CUDA 4.2 project in visual studio 2010 and compiled them, Here is the result.

顺便说一句，我可以在这个 vs2010 CUDA 项目下运行其他示例，例如时钟、matrixMul 等.(这意味着包含路径设置正确)

By the way, I can run other samples such as clock, matrixMul, etc. under this vs2010 CUDA Project. (This means the include path is set correctly)

我用谷歌搜索并找到以下链接 一些问题CUDA 内核操作中的原子添加.我根据它更改了项目和.cu文件的属性，但仍然无法解决问题.

I googled it and found the following link Some issue with Atomic add in CUDA kernel operation. I changed the properties of both project and the .cu file according to it, but still can't solve the problem.

有什么建议吗?

推荐答案

Atomics 在计算架构 1.0 下不可用，但您仍在尝试根据构建日志对其进行编译.尝试从您的 CUDA 项目属性中删除对 compute_10 和 sm_10 的引用，并仅针对计算架构 2.0(GeForce 400 系列和更新版本)进行编译.

Atomics are unavailable under compute architecture 1.0, but you're still trying to compile for it according to your build log. Try removing references to compute_10 and sm_10 from your CUDA project properties and compiling for just compute architecture 2.0 (GeForce 400 series and newer).
