XSEDE Allocations award eligible users access to compute, visualization, and/or storage resources as well as extended support services.
XSEDE has various types of allocations from short term exploratory request to year long projects. In order to access to XSEDE resources you must have an allocation. Submit your allocation requests via the XSEDE Resource Allocation System (XRAS) in the XSEDE User Portal.
