I've heard that AMD has a plan to release AMD’s gem5 APU Simulator this year.
What is an official site where we can download the simulator?

Yes, we have released our gem5 GPU compute model that executes HSAIL kernels. You can download gem5, which includes our GPU additions, from http://repo.gem5.org/gem5. There is also a tutorial available on line that describes our additions and how to use them: http://gem5.org/gpu_models
Please let me know if you have any questions,
