WebLocal memory - available to all the processing elements in a compute unit. Private memory - available to a single processing element. OpenCL Memory Model. OpenCL memory management is explicit. None of the above memories are automatically synchronized and so the application explicitly moves data between memory types as needed. WebIn OpenCL, multiple work-items are grouped together to form workgroups. In the figure above, each workgroup size is 8×4 comprising a total of 32 work-items. Work-items in a workgroup can synchronize with one another and share data using local memory (to be explained in a later article). OpenCL execution on the PowerVR Rogue architecture
WebLocal Memory Usage. One typical GPU-targeted optimization uses local memory for caching of intermediate results. For CPU, all OpenCL™ memory objects are cached by hardware, so explicit caching by use of local memory just introduces unnecessary (moderate) overhead.
