some optimization for the main.cc code. 1. add __device__ and __restrict__ decoration for style uniform and performance. 2. an error in function call, in line: cudaMemcpyToSymbol(&cFoo, &bar, sizeof(int)); the first parameter should be pointer type. 3. Hope you can send me your book. :)
delete the __device__
we already input N/2 in kernel launch function point, if we divide/2 here, the result is always wrong, seems half of the original result.

sorry, maybe the line 76: cudaMemcpyToSymbol(&cFoo, &bar, sizeof(int)); modification is wrong.
please ignore this line.
