GenApp is a framework for rapidly building and deploying graphical front ends for underlying computational modules. GenApp builds full featured applications on an extensible 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. - Prerequisites: Participants should bring a laptop with an SSH client and modern web browser installed. Working knowledge of some text editor under Linux is required, such as nano, vi or emacs. The instructors will arrange for students to have access to cloud based training accounts. - Recommended Skill Level: It is expected for attendees to familiarize themselves with the material covered in the GenApp basics tutorial available at http://genapp.rocks/learn. On-line training will be available beforehand to assist attendees with the GenApp basics, if requested. For more information on additional training or to ask any questions, please subscribe to the users’ mailing list at http://genapp.rocks/join.
