T. Hoefler:

 Performance-oriented Parallel Programming Integrating Hardware, Middleware, and Applications

(Presentation - presented in Savannah, GA, USA, Feb. 2012)
SIAM SIAG/SC Junior Scientist Award Lecture


Parallel programming is hard, optimizing parallel programming is even harder, and writing optimal parallel programs is nearly impossible. In this talk, we discuss how optimizing communication in parallel programs routinely requires to deal with low-level system details. We show portable abstractions that enable transparent optimizations but require advanced techniques in the lower layers. We conclude that scaling to larger machines demands an holistic approach to integrate hardware, middleware, and application software to develop performance-portable parallel programs.
