WebSummary. Shared memory is a powerful feature for writing well optimized CUDA code. Access to shared memory is much faster than global memory access because it is located on chip. Because shared memory is shared by threads in a thread block, it provides a mechanism for threads to cooperate. WebWe should point out that our deviceProperties() function is not a CUDA API function. Since it encapsulates the cudaGetDeviceProperties() CUDA function within its implementation, we could wrap the ERRORHANDLER() macro directly around it within the deviceProperties() function definition.
