These workshops are offered with funding provided by the National Science Foundation through the XSEDE program, and with additional funds from NCSI. As such, there in no fee to attend any NCSI/XSEDE workshop this year. Meals and breaks during the workshop will be provided to all participants. While most participants are expected to be within commuting distance of the workshop location, a limited number of spaces in each workshop will be available for those traveling to a workshop from a greater distance and who would need housing. For those accepted to a workshop, this housing (double occupancy) will be provided at no cost to the participant. Those requesting single occupancy will be responsible for the difference. Subject to funding, a limited number of travel scholarships may also be available to more distant faculty interested in attending the workshops. The scholarships will provide partial or full reimbursement of travel costs to and from the workshops. Preference will be given to faculty from institutions that are formally engaged with the XSEDE education program and to those who can provide some matching travel funds. Recipients are expected to be present for the full workshop. Those interested in a travel scholarship should complete the scholarship application, which can be submitted after you apply for the workshop and is available from the page where you review your application.
