Research requests for XSEDE allocations are accepted quarterly and reviewed by the XSEDE Resource Allocations Committee (XRAC). The XRAC is a panel of academic and industry computational experts who evaluate the requests and recommend allocation awards. XSEDE is always on the lookout new volunteers to serve the research community as XRAC members rotate off. Contact help@xsede.org if you are interested. Any U.S.-based investigator supported by most forms of research funding is eligible to apply for XSEDE allocations. See www.xsede.org/for-users/getting-started for more details on what XSEDE offers.
