About XSEDE User Portal
The XSEDE User Portal is a web-based single point of access to the following services:
- Access to all your XSEDE accounts and allocated resources
- Method to request compute, data, and extended support allocations resources for individual projects, Science Gateways, and for classroom training
- Interfaces for data management, data collections, and other user tasks and resources
- Access to the XSEDE Knowledge Base, Help Desk, and online training
You can register for an XSEDE User Portal account for free anytime with no allocation. You can only get an account on a resource as part of an allocation, so you either need to apply for an allocation (see Get an Allocation) or be added to an existing allocation (see Adding a User).
Apply for an XSEDE allocation
An allocation is an award of computing time on the computing resources of your choice. Only those users with an allocation may access XSEDE resources. A user may request either a Startup (or Education) Allocation or a Research Allocation. Both types of allocations include:
- An allotment of Service Units (SUs) where 1 SU = 1 hour of computing on 1 CPU. Startup allocations vary in allotment size, while a Research Allocation allotment is unlimited.
- Archival storage
Request a Startup allocation
Submit an allocation request via the XSEDE portal. To complete the form, you will need the following information:
- An estimate of the computing time needed in SUs, or an estimate of the amount of storage needed (in Terabytes, or TB).
- A short abstract of your computational project
- The Principal Investigator's CV
Startup allocations vary in allotment size, depending on the resources requested. The total Startup allocation across all resources cannot exceed 200,000 SUs. For resource specific Startup limits, please see: XSEDE Resource Catalog for more information.
Startup and Educational requests are reviewed year-round. This type of allocation is aimed at users who want to test and develop their code on XSEDE, for users wanting to try out resources, for users with limited data needs, or for classroom teaching situations. Features and uses of the Startup/Educational allocation include the following:
- Experiment with code(s) and task(s) on the various resources for one year
- Find the best mapping of your research task flow to the resources
- Document this mapping to write a Research Allocation Request: define a science goal and discuss how many SUs you will need on which systems to accomplish it over one calendar year
- Easier request process requiring a curriculum vitae and abstract (compared to a full request as in the Research Allocation request).
Request a Research allocation
For Research Allocations, a more detailed request is required. The process is outlined on the Allocations and Accounts page. Requests for Research Allocations require a more extensive application process and uploading of supporting documentation.
Submit your allocation request
Submit your request electronically via the XSEDE portal. Users will be notified via email when their allocations are approved or when they have been added to an allocation. Principal Investigators will be able to delegate an allocation manager who can manage their allocations for them. This will be done in the user portal under My XSEDE -> Allocations/Usage
Requesting extended support
A request for extended support to enhance the effectiveness and productivity of work can accompany any application for an allocation, or it can be submitted stand-alone as a Supplement to an active allocation. This request will be reviewed for its suitability to the allocated project. ECSS management will then seek to develop a feasible work plan for the collaboration between users and staff experts.
Requests must address these five questions:
- What do you want to accomplish with the help of extended support? Have you already done any work on this aspect of your software?
- How would the success of this extended support benefit your project?
- Which member(s) of your team would collaborate with XSEDE extended support staff?
- Have you had significant interaction on previous projects related to your current proposal or discussed your extended support needs with any XSEDE staff?. If so, please indicate with whom.
- Have you received TeraGrid/XSEDE extended support in the past?. If so, please indicate the time period, and how the support you received then relates to the support you request now.
User Responsibility & Security
As an XSEDE user, you'll have access to some of the best high performance computing and data resources in the country. Following are rules of acceptable use to protect these valuable, shared resources and intellectual property.
- If you have any suspicion that your account or personal computer has been compromised, email email@example.com or call 24/7: 1-866-907-2383 immediately.
- Save your Account Information Packet in a safe place; you will need it to reset your password.
- Do NOT share login information under any circumstances. It's easy for PIs to add users through the User Portal. In addition, community and training accounts are available for special situations.
- If individuals leave your project, use the same form to remove their account from your allocation.
- When changing passphrases and passwords, use strong passwords with mixed cases and character types.
- Don't use passwordless SSH keys (see the SSH page for details).
- Protecting computers, closing terminals when done, logging out of the XSEDE User Portal when done, etc.
