Bill Gropp on Engineering for Performance in HPC

In this video from the 2014 Platform for Advanced Scientific Computing (PASC) Conference, Bill Gropp from the University of Illinois presents: Engineering for Performance in High Performance Computing.

Achieving good performance on any system requires balancing many competing factors. More than just minimizing communication (or floating point or memory motion), for high end systems the goal is to achieve the lowest cost solution. And while cost is typically considered in terms of time to solution, other metrics, including total energy consumed, are likely to be important in the future. Making effective use of the next generations of extreme scale systems requires rethinking the algorithms, the programming models, and the development process. This talk will discuss these challenges and argue that performance modeling, combined with a more dynamic and adaptive style of programming, will be necessary for extreme scale systems.
