Startup allocations, along with Campus Champion and Trial allocations, are one of the fastest ways to gain access to and start using XSEDE-allocated resources. We recommend that all new XSEDE users begin by requesting Startup allocations.
Appropriate uses for Startup allocations include:
- Small-scale computational activities that require the unique capabilities of resources allocated through XSEDE
- Application development by researchers and research teams
- Benchmarking, evaluation and experimentation on the various resources
- Developing a science gateway or other infrastructure software components
Users may request a single resource or a combination of resources. Each request is subject to Startup Limits for each resource, shown in the Startup Request Resource Limits table below. Startup requests are further limited to no more than three separate computational resources, unless the abstract explicitly justifies the need for each resource to the reviewers' satisfaction.
Startup allocations last one year, and a Principal Investigator (PI) may be awarded only one active Startup project at a time. NOTE: If you have an existing Research or Startup allocation, and would like a Startup-scale allocation on a new resource for the purposes described here, please request a Supplement to your existing project.
Startup requests require minimal documentation: the project's abstract and the PI's CV. See below for requirement details and example Startup requests. You must have an XSEDE User Portal account in order to submit requests.
Upon approval of the Startup allocation request, PIs can request that other users be given accounts to use the allocation. See Managing Allocations.
Startup allocation requests are evaluated continuously throughout the year. Click here to submit your Startup request. Startup requests are typically reviewed and awarded within two weeks.
Startup allocations are available to faculty members and researchers, including postdoctoral researchers, at a U.S.-based institution. Eligible institutions include federal research labs or commercial organizations; however, special rules may apply if your institution is not a university or a two- or four-year college. Investigators with support from any funding source, not just NSF, are encouraged to apply.
Startup requests require the following elements:
- Project Abstract: The Project Abstract is the most important part of the submission. An ideal abstract will not only describe the research objectives of the project, but also explain briefly why the project needs access to XSEDE resources, state how the requested amounts were estimated, and note why the requested resources were selected.
- CVs (2 pages per CV): Startup requests require a curriculum vitae (CV) for the PI and for any listed co-PI. CVs should be two pages maximum, in standard NSF or NIH format. The Documents upload section will require a CV upload for the PI and each co-PI entered in the Co-PI information area.
- NSF Fellowship award letter (if applicable): Graduate students with NSF Fellowship or Honorable Mention awards are eligible to be PIs on a Startup allocation request. Enter your award information in the Supporting Grant section and attach a copy of your NSF award letter to their request.

Nearly 200 campuses across the country have designated "Campus Champions" to facilitate and support use of XSEDE-allocated resources by researchers, educators, and students on their campuses. Most Campus Champions have established projects on XSEDE resources, which campus users can access to evaluate systems, conduct benchmark runs, or carry out small-scale research projects.
Contact your Campus Champion for fast and easy access to XSEDE-allocated resources or to get help submitting your own allocation request.
Please consult the Campus Champions page for more on the program.
SDSC also offers Trial Allocations on its Comet cluster. Trial Allocations are designed to give potential users rapid, but limited access to the Comet resource. Trial allocations are 1,000 SUs for 6 months, sufficient for initial resource evaluation, giving new users the ability to compile and run software, and evaluate results. Within one business day, users will be able to log on and evaluate the Comet system prior to requesting a larger Startup or Research allocation.
