ABSTRACT
Datasets of tens of gigabytes are becoming common in computa-
tional and experimental science. This development is driven by ad-
vances in imaging technology, producing detectors with growing
resolutions, as well as availability of cheap processing power and
memory capacity in commodity-based computing clusters.
In this article we describe the design of a visualization system
that allows scientists to interactively explore large remote data sets
in an efficient and flexible way. The system is broadly applicable
and currently used by medical scientists conducting an osteoporosis
research project. Human vertebral bodies are scanned using a high
resolution micro-CT scanner producing scans of roughly 8 GB size
each. All participating research groups require access to the cen-
trally stored data. Due to the rich internal bone structure, scientists
need to interactively explore the full dataset at coarse levels, as well
as visualize subvolumes of interest at the highest resolution.
Our solution is based on HDF5 and GridFTP. When accessing
