Overview

Ocelot is a modular dynamic compilation framework for heterogeneous system, providing various backend targets for CUDA programs and analysis modules for the PTX virtual instruction set. Ocelot currently allows CUDA programs to be executed on NVIDIA GPUs, AMD GPUs, and x86-CPUs at full speed without recompilation.
