Creating Science Gateways using Advanced GenApp Capabilities

GenApp is a framework for rapidly building and deploying graphical front ends for underlying computational modules. GenApp builds full featured applications on an extensi- ble variety of web and local GUI-based targets. GenApp works by reading a collection of definition files which guide the assembly of code fragments to output the application. In particular, GenApp can build fully functioning science gateways with a rich set of features. Science gateways built with GenApp can utilize OAuth2 for users to register and log on with XSEDE, Google or other credentials. Underlying jobs can run on a variety of resources including direct execution via ssh, elastically via OpenStack, and on queue-managed resources via Apache Airavata. GenApp is currently being successfully used as the generator of multiple production science gateways. This 90 minute tutorial will cover practical usage of advanced user interface methods.
