Abstract:

Since the introduction of CUDA in 2006, we have made tremendous progress in heterogeneous computing. We have built heterogeneous top supercomputers. Most of the top supercomputers in the world are heterogeneous computing systems. We have mass-produced heterogeneous mobile computing devices. New standards such as the Heterogeneous Systems Architecture (HSA) are emerging to facilitate software development. Much has been learned about of algorithms, languages, compilers and hardware architecture in this movement. How hard is it to program these systems today? How will we programming these systems in the future? How will heterogeneity in memory devices present further opportunities and challenges? What is the impact on long-term software engineering cost on applications? In this talk, I will go over the lessons learned from educating programmers and developing performance-critical libraries. I will then give a preview of the types of programming systems that will be needed to further reduce the software cost of heterogeneous computing.
