Moore's Law continues to provide smaller semiconductor devices with greater degree of integration, necessitating massively parallel processors. One of the best example of such a massively parallel processor architecture is that of modern GPUs, which are currently powering 3 of the top 5 supercomputers. While today's GPUs are successful because of their high energy efficiency (GFLOPs/Watt), maintaining performance scalability will require significant changes to processor and system architecture. Specifically, it is necessary to continue to improve energy efficiency and overcome increasingly tighter bandwidth constrains and reduced component reliability. I will describe the NVIDIA-led Echelon research project, of which I am a member, which is developing architectures and programming systems that aim to address these challenges and drive continued performance scaling of parallel computing from embedded systems to supercomputers.
