6 Feb 2018 | Abstract: | Collaborations in astronomy and astrophysics are faced with numerous cyber
infrastructure challenges, such as large data sets, the need to combine
heterogeneous data sets, and the challenge to effectively collaborate on those
large, heterogeneous data sets with significant processing requirements and
complex science software tools. The cyberhubs system is an easy-to-deploy
package for small to medium-sized collaborations based on the Jupyter and
Docker technology, that allows web-browser enabled, remote, interactive
analytic access to shared data. It offers an initial step to address these
challenges. The features and deployment steps of the system are described, as
well as the requirements collection through an account of the different
approaches to data structuring, handling and available analytic tools for the
NuGrid and PPMstar collaborations. NuGrid is an international collaboration
that creates stellar evolution and explosion physics and nucleosynthesis
simulation data. The PPMstar collaboration performs large-scale 3D stellar
hydrodynamics simulation of interior convection in the late phases of stellar
evolution. Examples of science that is presently performed on cyberhubs, in the
areas 3D stellar hydrodynamic simulations, stellar evolution and
nucleosynthesis and Galactic chemical evolution, are presented. | Source: | arXiv, 1802.2233 | Services: | Forum | Review | PDF | Favorites |
