Designed especially for neurobiologists, FluoRender is an interactive tool for multi-channel fluorescence microscopy data visualization and analysis.
Deep brain stimulation
BrainStimulator is a set of networks that are used in SCIRun to perform simulations of brain stimulation such as transcranial direct current stimulation (tDCS) and magnetic transcranial stimulation (TMS).
Developing software tools for science has always been a central vision of the SCI Institute.

Steve Petruzza Presents:

Spatially-aware Parallel I/O for Particle Data

December 4, 2019 at 12:00pm for 1hr
Evans Conference Room, WEB 3780
Warnock Engineering Building, 3rd floor.


Particle data are used across a diverse set of large scale simula- tions, for example, in cosmology, molecular dynamics and com- bustion. At scale these applications generate tremendous amounts of data, which is often saved in an unstructured format that does not preserve spatial locality; resulting in poor read performance for post-processing analysis and visualization tasks, which typi- cally make spatial queries. In this work, we explore some of the challenges of large scale particle data management, and introduce new techniques to perform scalable, spatially-aware write and read operations. We propose an adaptive aggregation technique to im- prove the performance of data aggregation, for both uniform and non-uniform particle distributions. Furthermore, we enable efficient read operations by employing a level of detail re-ordering and a multi-resolution layout. Finally, we demonstrate the scalability of our techniques with experiments on large scale simulation work- loads up to 256K cores on two different leadership supercomputers, Mira and Theta.
