This tutorial will build upon the XSEDE15 (http://sched.co/3YdG) and XSEDE16 tutorials (http://sched.co/7F7l). The purpose of this tutorial is to supplement the standard XSEDE new user tutorial with overviews of how to use science gateways so that new users can start using XSEDE for scientific research right away, at the conference, and continue at their home institution, without getting bogged down in the allocation process at the beginning. The tutorial is also appropriate for XSEDE Campus and Domain Champions who are interested in using science gateways to support outreach and support work on their local campuses. The target audience members are scientists, in particular domains (chemistry, neuroscience, atmospheric science), who are new to XSEDE and who optionally are familiar with common software packages in their field, but who do not have deep experience with using supercomputers and clusters. Campus Champions who work closely with new users are also encouraged to attend. The tutorial will provide a brief overview of XSEDE and the science gateway program, including a list of other available gateways not covered by the tutorial. The bulk of the tutorial will be a sequence of hands-on activities that introduce attendees to domain specific gateways. The tutorial organizers will work with XSEDE conference organizers and the outreach team to recruit new user attendees from the selected domains. Prerequisites: Java will be required for part of the tutorial. Sample input files and other information can be found at
