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.

This is the third edition of the orange book. It covers GLSL 1.4 and entry points from OpenGL 3.1. As usual the book is part tutorial, part reference. Very well written, clear and concise. Check out the companion site.

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.

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.
