TALK TITLE: Performance and maintainability:  dealing with these
conflicting concerns in large community weather models.

ABSTRACT:
Computational requirements for atmospheric modeling, one of the first
applications of scientific computing, remains a challenge today. Soon, the
advent of tera-scale computer systems comprising hundreds or thousands of
parallel processors will enable simulation of complex phenomena at
unprecedented resolutions and scales. But only if scientific software is
able to exploit these systems while at the same time preserving the
considerable and ongoing investment in large community models. This
requires attention to maintainability, extensibility and
performance-portability across an increasingly diverse computer
architecture landscape, comprising both vector and cache-based processors
configured for shared- and distributed-memory parallelism. This talk
presents approaches to model software design and tools for dealing with the
conflicting concerns of performance and software maintainability in two
large numerical weather prediction community models: the
Penn State/NCAR Mesoscale Model (MM5) and the new Weather Research and
Forecast (WRF) model.
