I wrote the code.
val += __shfl_down(val, offset);
However error massage was shown.

1`__shfl_down` is compute capability 3.0 and above. Check the CC of your GPU. – user703016 Sep 22 '16 at 02:55

1You also need to compile with the -arch flag. If compute capability is more than 3.0. e.g. nvcc -arch=sm_52 foo.cu – kakrafoon Sep 22 '16 at 03:13
