A buffer object stores a one-dimensional collection of elements. Elements of a buffer object can be a scalar data type (such as an int, float), vector data type, or a user-defined structure.
An image object is used to store a one-, two- or three-dimensional texture, frame-buffer or image. The elements of an image object are selected from a list of predefined image formats. The minimum number of elements in a memory object is one.
Shared virtual memory (a.k.a. SVM) allows the host and kernels executing on devices to directly share complex, pointer-containing data structures such as trees and linked lists. It also eliminates the need to marshal data between the host and devices. As a result, SVM substantially simplifies OpenCL programming and may improve performance.
A pipe is a memory object that stores data organized as a FIFO.
The platform layer allows the host program to discover OpenCL devices and their capabilities and to create contexts.
Considering OpenCL 1.x as base.
A sampler object describes how to sample an image when the image is read in the kernel. The built-in functions to read from an image in a kernel take a sampler as an argument. The sampler arguments to the image read function can be sampler objects created using OpenCL functions and passed as argument values to the kernel or can be samplers declared inside a kernel.
