Scalable algorithms and applications Many of the most compelling computaitonal earth science problems require efficient use of computational resources. The ACES system will be used for further developing scalable numerical techniques for planetary scale systems. Some examples of planned ACES work in this area includes:
Ongoing development of scalable medium level complexity coupled modeling
systems.
Scalable approaches to gridding the sphere.
High-resolution tracer transport modeling with scalable I/O: Many fluid
Earth problems can be studied by using precomputed flow fields to transport
one or more tracer. Numerically these methods can be very efficient because
certain wave phenomena that restrict numerical simulation time steps are
absent from transport models. However, high resolution transport fields
require storing flow fields at high temporal frequency resulting
in potentially multi-terabyte datasets. To retain efficiency transport
models must, therfore, stream I/O in parallel in a scalable manner.
The network fabric in ACES will be used to further research techniques
that are already being applied at MIT to these problems.
