Abstract

The HUBzero platform for scientific collaboration enables tool developers to build tools that are easily shared with both researchers and educators. This enables users to login and start their analysis without worrying about setup and configuration of the tools. Once, the analysis is done researchers can then analyse the results using various inbuilt capabilities for plotting and visualization. To facilitate handling of more complex workloads, we have integrated Pegasus Workflow Management System with “submit”, the main tool used by tool developers in HUBzero to submit analysis to local and remote compute resources. Pegasus WMS provides a means for representing the application workflow in an abstract form which is independent of the resources available to run it and the location of data and executables. It compiles these abstract workflows into an executable form that can be executed on local or remote …
