ATTILA GPU Simulator



ATTILA is GPU simulator with OpenGL and D3D9 API implementations that can be used to simulate PC Windows game traces.

In the ATTILA source code included in this package you will find the classes used to build the simulator, the API implementations to run OpenGL and D3D9 game traces on this simulator, the API trace tools and a number of tools that had been used on the development of this project.

Some of the techniques and algorithms implemented in the simulator may be covered by patents (for example DXTC/S3TC compression or the Z compression algorithm).

No documentation about the source code, the simulator or the library is provided within this package. Check for documentation available documentation in the ATTILA wiki:

How to compile on GNU/Linux

Usage: make [clean | simclean]
       make [what options]

clean      - Delete all OBJs and binary files.
simclean   - Delete only simulator related OBJs, and binary files.

       all                  - Build ATTILA simulator and tools
       bGPU                 - Build ATTILA simulator and emulator
       gl2atila             - Build gl2atila
       extractTraceRegion   - Build extractTraceRegion


        CONFIG={ debug  | profiling | optimized | verbose }
            debug     - Compile with debug information
            profiling - Compile with profiling information
            optimized - Maximum optimization (default)

            <cpu>   - Target cpu for compilation. This lets apply some optimizations.
                      Possible values: x86, x86_64, pentium4, athlon, core2

        VERBOSE={ yes | no }
            yes     - Activate debug messages
            no      - Deactive debug messages (default)

            <platf> - Target platform for compilation.
                      Possible values: linux (default), cygwin
