Programming Exascale Supercomputers

SESSION: Broadening Participation in HPC and Supercomputing R & D

EVENT TYPE: Broader Engagement

TIME: 11:15AM - 12:00PM

SESSION CHAIR: Dorian C. Arnold

Presenter(s):Mary Hall


Predictions for exascale architectures include a number of changes from current supercomputers that will dramatically impact programmability and further increase the challenges faced by high-end developers. With heterogeneous processors, dynamic billion-way parallelism, reduced storage per flop, deeper and configurable memory hierarchies, new memory technologies, and reliability and power concerns, the costs of software development will become unsustainable using current approaches. In this talk, we will explore the limitations of current approaches to high-end software development, and how exascale architecture features will exacerbate these limitations. We will argue that the time is right for a shift to new software technology that aids application developers in managing the almost unbounded complexity of mapping software to exascale architectures. As we rethink how to program exascale architectures, we can develop an approach that addresses all of the productivity, performance, power and reliability
