Cuda threadid blockid
http://thebeardsage.com/cuda-threads-blocks-grids-and-synchronization/ WebThe CUDA API has a method, __syncthreads () to synchronize threads. When the method is encountered in the kernel, all threads in a block will be blocked at the calling location until each of them reaches the location. What is the need for it? It ensure phase synchronization.
