Barra: A Modular Functional GPU Simulator

May 4th, 2009

Barra, developed by Sylvain Collange, Marc Daumas, David Defour and David Parello from Université de Perpignan, simulates CUDA programs at the assembly language level (NVIDIA PTX ISA). Its ultimate goal is to provide a 100% bit-accurate simulation, offering bug-for-bug compatibility with NVIDIA G80-based GPUs. It works directly with CUDA executables; neither source modification nor recompilation is required. Barra is primarily intended as a tool for research on computer architecture, although it can also be used to debug, profile and optimize CUDA programs at the lowest level. For more details and downloads, see the Barra wiki. A technical report is also available.
