Interactive Supercomputing

These researchers use MSI’s Itasca system in support of a project to enable interactive supercomputing. The idea is that only a local center has the capability to provide the very high bandwidth data connection to a supercomputing resource that true interactive supercomputing demands. Itasca has sufficient scale to enable this use in a way that should not unduly disrupt other MSI activities. This project continues work previously carried out on the Calhoun system. The researchers aim to exploit the potential 20 Gbit/sec link from their lab, the LCSE, to the MSI machine room to perform special large runs from which detailed visualization output will be processed into movies. These movies will help guide the group’s scientific work and will also be used in outreach activities.

The scientific focus of this effort is in the study of the brief stages of stellar evolution in which three-dimensional effects play a dominant role. The researchers are also obtaining detailed data that they use for the formulation and validation of models of the turbulent flow phenomena that are involved in these stars as well as in other contexts of interest.
