Intel announces the alpha release of the Intel OpenCL SDK

Available at WhatIf.intel.com, this implementation delivers OpenCL 1.1 specification features optimized for Intel Core™ processors for developers desiring to explore CPU advantages found on many OpenCL workloads. Currently, Microsoft Windows 7 and Windows Vista operating systems are supported. Intel OpenCL SDK is a full implementation of the OpenCL 1.1 specification, including all API's and language features, and supports additional optional features and extensions such as: Out-of-order Execution model, Images support, Double precision floating point, OpenCL-OpenGL interoperability, and more. This SDK is not fully conformant yet.

Texture and buffer access performance in OpenGL

Currently there are several ways to feed data to the GPU no matter of what API we use and what type of application we develop. In case of OpenGL we have uniform buffers, texture buffers, texture images, etc. The same is true for OpenCL and other compute APIs that even provide more fine-grained memory management taking advantage of the local data store (LDS) available on today’s hardware. In this article I’ll present the memory access performance characteristics of AMD’s Evergreen-class GPUs focusing on what this all means from OpenGL point of view. While most of the data is about the HD5870, the general principles and relative performance characteristics are valid for other GPUs, including ones from other vendors.
