Description

cl_khr_initialize_memory adds OpenCL C support for initializing local and private memory before a kernel begins execution. This is accomplished by specifying a flag at context creation time affecting all such memory.

Memory is allocated in various forms in OpenCL both explicitly (global memory) or implicitly (local, private memory). This allocation so far does not provide a straightforward mechanism to initialize the memory on allocation. In other words what is lacking is the equivalent of calloc for the currently supported malloc like capability. This functionality is useful for a variety of reasons including ease of debugging, application controlled limiting of visibility to previous contents of memory and in some cases, optimization.

See the Initializing Memory section of the OpenCL C specification for more information.
