A notice from the XSEDE team advises that the XSEDE project is scheduled to end operations on Aug. 31, 2022. A new program, Advanced Cyberinfrastructure Coordination Ecosystem: Services & Support (ACCESS), is set to launch Sept. 1, 2022.

Please be aware that the information in this help documentation will be revised as soon as this transition has been completed.

In addition to local computational resources, the Extreme Science and Engineering Discovery Environment (XSEDE) is a powerful collection of national computing resources that can be used for research purposes, acting as a single virtual system that faculty, researchers, and scientists can use to collaborate and share computing resources, data, and expertise. For more information, or to discuss your HPC needs, please contact Jason Simms at simmsj@lafayette.edu.

What resources are available on XSEDE?

In general, available resources can be classifies as: High Performance Computing (HPC) machines, High Throughput Computing (HTC) machines, visualization, data storage, testbeds, and services. For a complete list, please visit the XSEDE Resources page.

How can I create an account and access XSEDE resources?

XSEDE accounts are free of charge and can be created at the XSEDE User Portal (XUP). Having an XUP account does not automatically grant you access to XSEDE resources or compute time on any XSEDE resource. Compute time on XSEDE resources is granted via the allocations process. You may apply for a new allocation or get added to an existing allocation.

What is an XSEDE allocation?

XSEDE Allocation is an application process where users are awarded access to compute, visualization, and or storage resources, as well as to extended support services. XSEDE has various allocations from short term exploratory request to year-long projects. In order to access XSEDE resources you must have an allocation.

What allocation types are available?

Once you have an account, you may apply for one of the following allocation types:

  • Startup: The fastest way to get started on XSEDE, Startup allocations require minimum documentation, are reviewed all year long, and are valid for one year. These are mainly for exploratory purposes and are usually used to generate preliminary results to support larger research allocation requests. Startup allocations have a maximum total allocation of 200K CPU hours or Service Units (SUs), though each XSEDE resource may have a different limit for startup allocations. New users are recommended to begin with a Startup allocation request. In addition, Trial allocations are also available, which facilitate rapid but limited access to the Comet cluster to compile, run, and evaluate programs even prior to requesting a Startup allocation.
  • Education: Education allocations are for academic or training classes such as those provided at a university that have specific start and end dates. In addition to training classes, education projects support classroom instruction. Education allocations are appropriate for academic courses or training classes having a registration number, class description, and known timeframe. Education requests have the same allocation size limits as Startup requests but can request access for up to three separate resources. Requests for use with a course can be renewed for subsequent offerings of that course. PIs on education allocations must be faculty.
  • Research: Research allocations are appropriate for projects that require substantial computational resources that, in general, will have been benchmarked through a Startup allocation. Research allocation requests are reviewed quarterly and require more formal documentation. Research allocations will be granted for one year and may be renewed or extended.

Who is eligible to request an allocation?

To apply, the principal investigator (PI) must be a researcher or educator at a U.S.-based institution, including federal research labs or commercial organizations, though additional information may be needed from researchers not affiliated with academic or non-profit research institutions. A postdoctoral researcher is eligible to serve as PI. After receiving an allocation, PIs can request that students be given accounts to use the allocation. For more information, please read the complete allocation-related policies.

How do I get started?

To get started, visit the XSEDE documentation portal. Please visit the detailed list of XSEDE computing, visualization and storage resources at each of the partner sites, with links to detailed specifications and user guides for each machine.

Does Lafayette have a campus contact?

Yes! Jason Simms (simmsj@lafayette.edu) and Bill Thompson (thompsow@lafayette.edu) are XSEDE Campus Champions and can assist with questions.

What training is available for XSEDE?

XSEDE offers training throughout the year listed on the XSEDE Course Calendar and maintains a collection of online training resources.
