The purpose of this assignment is to familiarize yourself with CUDA programming.

In this problem, you need to use CUDA to parallelize concurrent wave equation serial_wave.c.

• The output format should not be changed.
• Your submitted solution contains only one source file, which is named wave.cu.
• Your program take two command-line arguments, which indicate the number of points and the number of iterations, respectively.

The GPU(s) in the server is an nVidia K20.

Usage:python test/run_test.py n steps

The difference of serial output with cuda output in fourth decimal place is normal.
