其他例子如何运作正常。甚至devicequeryDrv正确编译。

我还使用smokeParticle示例获取浮点异常

感谢您的帮助

Answer 1

CUDA驱动程序版本/运行时版本4.2 / 4.0

看起来您的CUDA驱动程序和运行时版本有不同的版本。当两者相同时，你得到seqfault吗？尝试重新安装4.2并确保所有工具都指向正确的工具包版本。

Answer 2

请检查您的驱动程序是否更新/正确 - http://developer.nvidia.com/cuda/cuda-downloads...you可以通过在此页面上提供您的GPU信息找到正确的驱动程序 - http://www.nvidia.com/Download/index.aspx?lang=en-us

Answer 3

我不知道发生了什么，但是当我使用cula的最新版本时，我得到的是相同版本的cuda运行时和驱动程序，但是当我降级到像r12这样的旧版本时，它会自动降级降级我的cuda运行时版本并导致错误。我测试了三次（升级，降级）。我不知道有可能/
