TERRA-NEO

Integrated Co-Design of an Exa-Scale Earth Mantle Modeling Framework

Scientific area

Modeling and simulation of earth mantle dynamics.

Short description

TERRA-NEO is based on a carefully designed multiscale space-time approximation, built on modern finite element technology and communication-avoiding ultra-scalable multigrid for multi-physics Earth mantle models. The TERRA-NEO software framework is developed specifically for the upcoming heterogeneous exa-scale computers by using an advanced architecture-aware co-design approach that is driven by a systematic performance engineering methodology.
