The device-side memory model defines the abstract memory spaces that work-items within an OpenCL application may target when executing a kernel. The memory model also defines the memory consistency that work-items can expect in each memory space. This chapter discusses each memory space in detail, describes the mapping of memory objects to memory spaces, and introduces ...
