  • Publications that have resulted from the use of XSEDE resources should be entered into your XSEDE portal profile which you will be able to attach to your Research submission. Please cite XSEDE in all publications that utilized XSEDE resources. See
  • After the Panel Discussion of the XRAC meeting, the total Recommended Allocation is determined and compared to the total Available Allocation across all resources. Transfer of allocations may be made for projects that are more suitable for execution on other resources; transfers may also be made for projects that can take advantage of other resources, hence balancing the load. When the total Recommended considerably exceeds Available Allocations a reconciliation process adjusts all Recommended Allocations to remove over-subscription. This adjustment process reduces large allocations more than small ones and gives preference to NSF-funded projects or project portions. Under the direction of NSF, additional adjustments may be made to achieve a balanced portfolio of awards to diverse communities, geographic areas, and scientific domains.

If you would like to discuss your plans for submitting a research request please send email to the XSEDE Help Desk at Your questions will be forwarded to the appropriate XSEDE Staff for their assistance.
