Conflict between gcc parallel mode stc and nvcc

Question

Conflict between gcc parallel mode stc and nvcc

I am encountering a conflict between nvcc and gcc 4.8.4 and cuda8.0. When I compile the following code to a.cu:

#include <parallel/algorithm>

int main(){
}

with cmd:, nvcc -std=c++11 -arch=sm_20 a.cu -o a.o

I got the following error message:

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).
