Distributed Multi-tenant In Situ Analysis Using Galaxy

Galaxy is a multi-tenant server platform for visualization and analysis of data distributed across many nodes of a supercomputer. It presents an interface through which multiple concurrent clients can connect to perform visualization and analysis tasks on shared data. Galaxy minimizes the memory footprint of visualization and analysis tasks to reduce the impact of analysis on the simulation. It does so by utilizing a visualization renderer that incorporates common visualization techniques directly in the rendering process. The client GUI provides a data-flow programming paradigm that enables users to connect to the Galaxy Multiserver, devise complex multi-step analytics workflows, and visualize results on their desktop.
