Improving graphics programming with shader tests

This paper presents an automated model and a project, Arrakis, for finding defects in shading algorithms for graphics rendering and compute workloads. A key challenge in shading algorithm testing is the lack of an oracle that can determine the quality and the output of a custom shading algorithm; this is crucial in graphics workloads because expensive assets are often wasted on solving these problems. A broad solution, Arrakis is developed, which builds on current graphics technology advances in Vulkan, SPIR-V and SPIRV-X by leveraging the standardization with mappings from SPIR-V and C++. Findings show that utilizing the demonstrated technology can improve quality whilst increasing productivity.
