The code renders a nice square pattern used to demonstrate the necessity of thread syncing between all the threads in a block. Each square is rendered by a block of threads in parallel. The first output shows how without thread syncing asynchronous reads and writes can result in unpredictable behavior and the second output is the same code but with a call to syncthreads() at the right time allowing for synchronization between the threads resulting in the expected output. The code is an implementation and extension of the example given in the second chapter of the book 'CUDA by Example' written by Jason Sanders.
