In the previous chapter we discussed about the OpenCL Architectural models, and also understood the device context and command queue creation. This forms the first step towards the OpenCL language programming. In Chapter 1, Hello OpenCL, we implemented a simple
saxpy OpenCL example, which created memory objects (buffers in this case) and the kernel performed the
saxpy operation on these buffers. These memory objects were created and transferred to and from the device's memory. Computations were performed on these memory objects by every instance of the kernel execution created in the NDRange. OpenCL memory objects form the most fundamental architectural unit in the OpenCL programming.
In this chapter we will study ...
