FixStars has just released their OpenCL book online. This book has been available in Amazon and other stores and now its free. The sample code is also available..

AMD CodeAnalyst for Windows® | AMD Developer Central.

AMD CodeAnalyst Performance Analyzer for Windows is a suite of powerful tools that help developers optimize software performance. CodeAnalyst uses profiling to identify and analyze performance hotspots within an application, library, driver or kernel module. CodeAnalyst profiles both managed and native code. CodeAnalyst collects system-wide profile data with low overhead and is well-suited for multi-threaded, multi-core development. Software under analysis executes at full speed.

GPU Tools | AMD Developer Central.

AMD has an excellent  collection of tools for OpenCL and Shader development in the GPU Tools area. Included are PerfStudio, a performance analysis and debugging tool, and ShaderAnalizer for analysing the performance of individual shaders. Currently they only work with Compatibility Profile, hope an update will cover the more recent versions.

The PipelineKit is an open source project originated at AMD to develop a visual and high level programming environment for OpenCL and DirectCompute applications running on GPUs, APUs and multi-core CPUs. A textual pipeline description language describes buffers, kernels, uniforms, invariants, and control graphs with stages that together comprise a computational pipeline. A pipeline generator compiles that description into C++ and OpenCL or DirectCompute code that executes the specified control graphs while preserving the specified invariants at runtime. The generator also produces a framework for unit testing; some debugging/data capture features, as well as templates for the corresponding kernels or ComputeShaders. Software developers are responsible for filling in the kernels or ComputeShaders. The PipelineKit and the code it generates run on Linux, Mac OS and Windows. It supports multiple GPUs within a workstation and provides barrier synchronizations among graphs running on different GPUs. Recently work has begun on a visual editor that lets you directly edit the control and data flow graphs (please see screenshot). This editor is a functional prototype.

gDEBugger – OpenGL and OpenCL Debugger, Profiler and Memory Analyzer.

A must have tool. It profiles your code using OpenGL with GLSL, showing the number of function calls, your data on the graphics hardware, shaders, uniforms, vertex data, … you name it. You can establish breakpoints at OpenGL functions and run it function by function, or frame by frame. It does not require any additions to your code, and even tells you if you’re calling deprecated functions.

Khronos Developer Presentations Library. The library has been updated with the presentations from GDC 2011, from the 28th of February to the 4th of March, at the Moscone Center in San Francisco, USA.

The presentations cover OpenGL, OpenCL, WebGL, amongst other topics.

OpenCL Studio is a tool that integrates OpenCL and OpenGL in a single development environment. There is a free version that is limited only in the number of items in your project tree.

The app has a few demo projects, and there are video tutorials on the site.
