Academic publication

GraphicsFuzz started as an academic research project by the Multicore Programming Group at Imperial College London. Check out our article published at the OOPSLA 2017 conference.

Our technology

GraphicsFuzz testing framework

The GraphicsFuzz testing framework automatically exposes bugs in graphics drivers in a simple form that supports debugging.

The "How it works" page explains how!

Our key technology enables detection of bugs that lead to an incorrect image being rendered, often the symptom of a shader miscompilation. Rigorously testing for such bugs without our technology is extremely challenging, and so is typically not done. Thus, these bugs are released into production where they will eventually be found by end users and developers, leading to damaged reputation and, in some cases, severe security bugs.

Intelligent reducer

Even after finding bugs using our technology, the process of fixing these bugs would normally be extremely time-consuming, requiring a huge number of developer-hours. Our intelligent reducer tool analyses the bugs and creates simplified bug reports that dramatically decrease the time needed to understand and fix the underlying bugs.

Our reducer is intelligent in two different ways:

  1. Our reducer is able to simplify inputs that trigger miscompilation by utilising information embedded in the input by our GraphicsFuzz framework.
  2. Our reducer is able to understand the semantics of the shader language, allowing for faster and more precise simplification than that which could be offered by any general-purpose reducer.

The "How it works" page illustrates this process!
