What types of XSEDE allocations are available?

An allocation on the Extreme Science and Engineering Discovery Environment (XSEDE) is a grant that provides approved research projects with 12 months of access to the XSEDE cyberinfrastructure. Allocations may include computing and visualization time, data storage space, and extended collaborative support services at one or more XSEDE service provider sites. Allocations are awarded to researchers who serve as principal investigators (PIs) of approved projects. After receiving an allocation, each project's PI can create XSEDE accounts for other researchers on the project team, giving them access to the project's allocated digital services.

XSEDE offers four types of allocations (described below) to accommodate various use cases.

On this page:


Startup allocations

Startup allocations are intended primarily for researchers who are new to the XSEDE environment, enabling them to quickly gain access to XSEDE digital services. They are well suited for researchers who need to develop their codes, test their applications, or experiment with XSEDE systems.

If this is your first time requesting an XSEDE allocations, you should most likely request a Startup allocation. Faculty members and postdoctoral researchers at US academic research institutions, as well as K-12 teachers, are welcome submit requests for Startup allocations at any time through the XSEDE User Portal.

Startup allocations provide each project with a maximum of 200,000 service units to be used within the 12-month time limit. You may request time on either a single computational system or a combination of systems. If needed, you may also request consulting and support from Extended Collaborative Support Service (ECSS) staff. Additional justification is required for ECSS support requests.

A PI may have only one active Startup allocation at a time. Although renewals for Startup allocations are permitted with appropriate justification, a PI with an expiring Startup allocation should consider requesting a Research allocation to continue work on XSEDE.

Education allocations

Education allocations are specifically designed for academic instruction or training activities, and are intended for faculty who want to incorporate XSEDE digital services into to their courses about the use of advanced cyberinfrastructure technologies.

PIs on Education allocations must be faculty at a US academic institution. You are welcome to submit a request for an Education allocation at any time through the XSEDE User Portal.

Research allocations

Research allocations are reserved for projects with requirements that Startup allocations cannot accommodate. With a Research allocation, an approved project can make extensive use of XSEDE's high-performance and high-throughput compute systems, scientific visualization systems, and data storage systems, and receive expert consulting and support from Extended Collaborative Support Service (ECSS) staff.

Requests for Research allocations are reviewed four times a year by the XSEDE Resource Allocations Committee (XRAC). Research allocation requests may be submitted using the XSEDE User Portal, but each request must include a detailed document that describes the work the project plans to accomplish and justifies the need for the requested resources. Additional justification is required for ECSS support requests.

Campus Champions

Campus Champions allocations are reserved for the Campus Champions representatives. The Campus Champions program functions by establishing representatives at US educational institutions who distribute knowledge of XSEDE's advanced cyberinfrastructure technologies to the researchers, educators, and students on their campuses.

Campus Champions are expected to help users on their campuses set up Startup allocations and provide them with the XSEDE contacts they need to resolve any problems. Campus Champions are also responsible for hosting training and information sharing sessions on their campuses to make researchers, faculty, and students aware of XSEDE's resources and services, and how XSEDE can help them achieve their research goals.

To inquire about joining the Campus Champions program, email the program coordinator at  champion-info@xsede.org . The role of Campus Champion representative is best suited for an information technology professional staff member, researcher, or faculty member with a passion for engaging colleagues. For more, see the program's Overview and How it Works pages.
