How do I apply for a new XSEDE allocation?

Instructions that will guide you through the entire process of submitting a new Extreme Science and Engineering Discovery Environment (XSEDE) allocation request are available in the XSEDE User Portal; see Getting Started.

Note: As of August 20, 2014, XSEDE has transitioned from the legacy allocation request system (POPS) to the new XSEDE Resource Allocation Service (XRAS). The transition process included a migration of all prior allocation submissions and allocation data. Upon accessing XRAS, users should see all prior allocation requests they submitted via POPS.

In summary, the allocation request process involves the following tasks:

  1. Determine your eligibility.

    To apply for an allocation on the Extreme Science and Engineering Discovery Environment (XSEDE), the principal investigator must be a researcher or an educator at a US-based institution, including federal research labs and commercial organizations (additional information may be needed from researchers not affiliated with academic or non-profit research institutions). Postdoctoral researchers are eligible to serve as principal investigators. In general, XSEDE follows guidelines described in the National Science Foundation (NSF) Grant Proposal Guide. Principal investigators with support from any funding sources (i.e., not just NSF-funded projects) are encouraged to apply. If your institution is not a university or a two- or four-year college, special rules may apply.

  2. Determine which type of XSEDE allocation is appropriate for your project. To learn about the different types of XSEDE allocations, see Allocations Overview in the XSEDE User Portal (no login required).

    Requests for Startup and Education allocations are accepted and reviewed continually throughout the year (i.e., there are no deadlines).

    Requests for Research allocations are reviewed by the XSEDE Resource Allocations Committee (XRAC) on a quarterly basis. Submission periods for the quarterly allocation start dates are:

    Submission period Allocation start date
    September 15 - October 15 January 1
    December 15 - January 15 April 1
    March 15 - April 15 July 1
    June 15 - July 15 October 1

  3. Determine which XSEDE digital services are best suited to meet your project's computational, visualization, and storage needs. To compare platforms and specifications of currently allocatable XSEDE digital services for computing, visualization, and storage, see Systems Monitor in the XSEDE User Portal (no login required). Alternatively, to view each system's user guide, see User Guides.
  4. Estimate the number of service units (for computational and visualization resources) and gigabytes (for storage resources) you are likely to need to accomplish your research objectives.

    Compute and visualization services are allocated in service units (SUs), which are defined locally on each system; see On XSEDE digital services, how are compute jobs charged?

    Storage services are allocated in gigabytes (GB). To request an allocation on an XSEDE storage system, you will need to prepare a detailed plan for managing your project's data storage needs in a cost-effective manner. For resources that can help you prepare your data management plan, see What resources are available to help determine my project's data storage needs for the preparation of a data management plan supporting an XSEDE storage allocation request?

  5. Create an XSEDE User Portal account; see What is the XSEDE User Portal, and how do I create an account? The principal investigator will need the account to access to the XSEDE Resource Allocation Service (XRAS).
  6. Log into the XSEDE User Portal, and then access the XSEDE Resource Allocation Service (XRAS) to submit your allocation request.

    Note: You should have a current copy of your curriculum vitae (CV) available in either Microsoft Word (.doc), HTML, PDF, or PostScript format.

Requests for Startup or Education allocations are reviewed by XSEDE Allocations Committee. The committee will email principal investigators within two weeks to notify them whether or not their requests are approved.

Principal investigators submitting successful Research allocation requests will receive email notifications typically two weeks before the allocation start date. Principal investigators whose Research allocation requests are not approved will receive email notifications with links to reviewer comments and instructions from the XSEDE Allocations Coordinator for reworking their proposals. Based on guidance from XSEDE, principal investigators may resubmit their proposals during the next submission period.
