Nirvana Case Studies | Hayden Planetarium Visualization Project

Area
Cosmology, simulation

Problem
Significant computing and storage capabilities are required to support cosmological simulation and visualization of large data collections. The Hayden Planetarium Visualization Project was a highly distributed collaboration across the United States. Simulations were run for several weeks at the National Center for Supercomputing Applications (NCSA) on a massively parallel SGI system. Simulation data was replicated over the WAN using Nirvana to the San Diego Supercomputing Center (SDSC) for analysis.

Participants
The Hayden Planetarium http://www.amnh.org/our-research/hayden-planetarium
The National Center for Supercomputing Applications http://www.ncsa.illinois.edu/
The San Diego Supercomputing Center, http://www.sdsc.edu

Data Sizes
30,000 files

Nirvana Solution
Nirvana was used to provide geographically distributed data access across a collaborative environment between California, Illinois and New York. At the SDSC , Nirvana managed 10,000 files in SDSC’s High Performance Storage System (HPSS). Part of the data set was also replicated into NASA's Nirvana resource. The visualization produced additional data managed by Nirvana including movie files for the Hayden Planetarium. Nirvana was used on a daily basis for data exchange between all collaborators during several months of the project.

Customer comments
The project wouldn't have been possible without Nirvana.
