Plasma
fusion experiments and simulation codes generate ever larger data sets, which
must be analyzed and visualized rapidly. However,
present commercial software packages for analysis and visualization of
scientific data cannot effectively process terabyte or multi-gigabyte data sets,
because they use only a single processor. Such
applications are too slow for interactive use and also require a computer with
enough dynamic memory to hold a significant fraction of the entire data set.
This project will develop a parallel implementation for a commercial
application that is widely used within the plasma fusion community.
The parallel implementation will run on an arbitrary number of
processors, enabling fusion energy scientists to interactively analyze and
visualize large data sets in parallel. In
Phase I, a prototype of the parallel data analysis and visualization software
will be developed. This prototype
will be used with data from an active tokamak experiment to demonstrate its
value to the plasma fusion community. The
performance increase using many processors will be demonstrated.
An approach to parallel volume visualization of a scalar field relevant
to tokamak experiments will also be investigated.
Commercial
Applications and Other Benefits as described by awardee: A parallel
implementation of existing commercial software for data analysis and
visualization should directly
benefit fusion energy scientists who must analyze and visualize large
experimental and simulated data sets. Other
markets include medical imaging.
