如何在 Visual Studio 2010 中设置 CUDA 编译器标志? [英] How to set CUDA compiler flags in Visual Studio 2010?

问题描述

在持续收到 error : identifier "atomicAdd" is undefined 之后，我找到了使用 -arch sm_20 标志编译的解决方案.但是如何在 VS 2010 中传递这个编译器标志呢?我在 Project > 下尝试过这样的尝试属性:

After persistently getting error : identifier "atomicAdd" is undefined, I've found the solution to be to compile with -arch sm_20 flag. But how to pass this compiler flag in VS 2010? I have tried like so under Project > Properties:

但这显然没有效果，错误仍然存​​在 - 我做错了什么?

But this apparently has had no effect and the error persists - what am I doing wrong?

非常感谢.

推荐答案

您可以在此对话框中选择 GPU 代码生成的选项:

You can select the options for the GPU Code Generation in this dialog:

在这种情况下，compute_20"表示我正在为虚拟计算架构 2.0 进行编译 - 虚拟架构影响 PTX 生成阶段.

In this case "compute_20" means that i am compiling for the virtual compute architecture 2.0 - virtual architecture influences the PTX generation stage.

昏迷之后的第二部分是sm_21".这会影响CUBIN生成阶段.它定义了我想要将 PTX 编译到的真实 GPU 架构.

The second part that comes after the coma is "sm_21".This influences the CUBIN generation stage. It defines the real GPU architecture i want to compile the PTX to.

您可以找到控制代码生成的 nvcc 命令行参数的详细说明 此处.

You can find detailed description of the nvcc command line parameters that control the code generation here.
