What I have been providing groups interested in getting letters of collaboration with XCRI for inclusion in their proposal:
The NSF-funded XSEDE project provides assistance in integrating cyberinfrastructure resources on campus and helping them adopt best practices of national cyberinfrastructure. The XSEDE Cyberinfrastructure Resource Integration (XCRI) team is available to provide training/documentation, software packages, and on-site consulting visits to assist with integrating campus clusters. Our project team will work closely with XCRI to plan system implementation and configuration to meet the needs of our users. XCRI works closely with campuses it supports but ensures that knowledge transfer on software and configurations are made to bolster the abilities of staff supporting the resource. Our team will join with the community of adopters of XCRI software in order to continue support activities and develop expertise among our own staff.
