Portability Among HPC Architectures for Scientific Applications

SESSION: Portability Among HPC Architectures for Scientific Applications

EVENT TYPE: Workshops

EVENT TAG(S): Architectures, Applications

TIME: 9:00AM - 12:30PM

Organizer(s):Timothy J. Williams, Tjerk P. Straatsma, Katie B. Antypas

ROOM:Hilton Salon G

ABSTRACT:

This workshop will explore how the large-scale scientific HPC developer community can and should engineer our applications for portability across the distinct HPC architectures of today, the next generation of large systems, and on toward exascale. How should HPC centers advise computational scientists to develop codes that scale well, have good aggregate and single-node performance, yet are as source-code portable as possible across the system architectures. We invite developers who have already faced this challenge in running across distinct present-day architectures to present their lessons learned and pest practices, and developers who are targeting the next generation HPC systems, such as those coming in the 2016-2018 time frame. How do we handle threads, vectorization, and memory hierarchies in as general a way as possible? Do we need to revise our data structures, when they may need to be different to map efficiently on different architectures?
