New Approach to Science Data Discovery in Petascale Systems

With the information age has come a dramatic increase in our ability to generate and collect data while the traditional techniques to analyze this tsunami of data have proven woefully inadequate. The amount of data collected and stored electronically is doubling every three years. Many researchers are simply overwhelmed by the amount of data. Scientific visualization remains the dominant form of data exploration but current tools are focused on image creation and lack the much needed embedded analysis capabilities. To address this urgent need, we propose to develop and introduce a first-of-its kind tool kit called SciViz2. SciViz2 brings together key innovations in three separate fields of scientific visualization, data mining, and computer vision to offer an integrated solution for physics mining of the most complex of data sets; multi-dimensional, multi-variate data sets. SciViz2 bridges the existing gap in software technology by providing a scalable knowledge discovery tool that combines the power of machine learning techniques with scientific visualization. Our Phase I goal is to develop a prototype and demonstrate the viability of the solution by applying it to one of the most challenging data analysis problem, that is the data from peta-scale particle simulations. The underlying physics involves complex interaction of multi-variates and the output involves both grid-based and particle phase space data with nearly trillion particles and over 200 TB of data from a single run. Phase II activity would involve full development of SciViz2 and its dissemination to the wider community. Our close collaboration with NASA's HPC group will be heavily leveraged to test and release the software for open use.

Non-NASA applications include laboratory experiments, and medical field, private industries such as oil companies, and the military and homeland security.

NASA applications include all its supported areas of research based on high performance computing. This includes heliophysics, astrophysics, planetary physics, space exploration, among others.

This is a mature technology (TRL 7) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
