我用gcc 4.8.4和cuda8.0来解决和nvcc之间的冲突。当我在a.cu中编译以下代码时：
#include <parallel/algorithm>
int main(){
}
使用cmd：nvcc -std=c++11 -arch=sm_20 a.cu -o a.o，我收到以下错误消息：
nvcc warning : The 'compute_20', 'sm_20', and 'sm_21' architectures are deprecated, and may be removed in a future release (Use -Wno-deprecated-gpu-targets to suppress warning).

我认为这是gcc并行模式STL代码和nvcc之间的冲突。 你有解决方法吗？任何信息都会有所帮助，谢谢！
