Question

我的GPU设备是GTX 1080Ti，IDE和CUDA版本分别是Visual Studio 2013和6.5，并且已经安装了Nsight 4.5插件。但是，当我启动CUDA调试时，IDE报告：

A CUDA context was created on a GPU that is not currently debuggable. Breakpoints will be disabled.

Adapter: GeForce GTX 1080 Ti

谁可以帮助我？

补充

实际上，我是基于基于CMake的project构建了该应用程序。为了适应环境，我在CMakeLists.txt中修改了一些代码。特别是以下代码段：

if (CUDA_VERSION_MAJOR GREATER 8)
  list(APPEND CUDA_NVCC_FLAGS "-gencode;arch=compute_30,code=sm_30;-gencode;arch=compute_35,code=sm_35;-gencode;arch=compute_50,code=sm_50")
else()
  list(APPEND CUDA_NVCC_FLAGS "-gencode;arch=compute_20,code=sm_20;-gencode;arch=compute_20,code=sm_21;-gencode;arch=compute_30,code=sm_30;-gencode;arch=compute_35,code=sm_35;-gencode;arch=compute_50,code=sm_50")
endif()

我已将其修改为

list(APPEND CUDA_NVCC_FLAGS "-arch;compute_20")

原因是如果我配置了旧项目，则总是发生"invalid device function"的运行时错误。结果，它会有所作为吗？

坚持调试CUDA应用程序
