XSEDE is a partnership of 19 institutions or "Service Providers" (listed below). XSEDE is led by the University of Illinois National Center for Supercomputing Applications (NCSA).

The original XSEDE program began in 2011 and had a 5 year funding life span. The current 'incarnation' of XSEDE is technically XSEDE 2. 

In addition to connecting researchers with computational resources, XSEDE provides a variety of training events and resources, chances to collaborate with computational science and cyberinfrastructure experts, tools for data analysis and visualization, opportunities forstudents, and much more.

In fact, since 2011, XSEDE and XSEDE 2 supported over $2 billion dollars worth of research awards from agencies like the National Science Foundation which have enabled competitive research across the nation.

XSEDE Partner Institutions


The National Science Foundation's eXtreme Digital program is making new infrastructure and next-generation digital services available to researchers and educators. They'll use that infrastructure to handle the huge volumes of digital information that are now a part of their work--the results of supercomputing simulations, the data generated by large scientific instruments such as telescopes, and the existing data that can be mined from a host of public sources. XSEDE is led by the University of Illinois' National Center for Supercomputing Applications. The partnership includes:

Which group is responsible for what?

XSEDE is divided into six Work Breakdown Structures (WBS). Each WBS has a unique responsibility listed below including brief descriptions of their mission.

WBS 2.1: Community Engagement & Enrichment (CEE)

The mission of Community Engagement & Enrichment is to support and promote workforce development, enhance user and campus engagement, broaden participation to underrepresented communities, and develop user interfaces and online information. 


WBS 2.2: Extended Collaborative Support Service (ECSS)

The Extended Collaborative Support Service improves the productivity of the XSEDE user community through successful, meaningful collaborations to optimize their applications, improve their work and data flows, and increase their effective use of the XSEDE digital infrastructure and broadly expand the XSEDE user base by engaging members of underrepresented communities and domain area.


WBS 2.3: XSEDE Community Infrastructure (XCI)

The mission of the XSEDE Community Infrastructure (XCI) team is to facilitate interaction, sharing and compatibility of all relevant software and related services across the national CI community building on and improving on the foundational efforts of XSEDE.


WBS 2.4: Operations (OPS)

The mission of XSEDE Operations is to install, connect, maintain, secure, and evolve an integrated cyberinfrastructure that incorporates a wide range of digital capabilities to support national scientific, engineering, and scholarly research efforts.


WBS 2.5: Resource Allocation Service (RAS)

The Resource Allocation Service (RAS) will build on XSEDE’s current allocation processes and evolve to meet the challenges presented by new types of resources to be allocated via XSEDE, new computing and data modalities to support increasingly diverse research needs, and large-scale demands from the user community for limited XSEDE-allocated resources.


WBS 2.6: Program Office (PO)

Provide consistent guidance and leadership to the L2 directors and L3 managers across the project and ensure the critical project level functions are in place and operating effectively and efficiently.

Learn more about how the functional areas of XSEDE contribute to the project's overall goals in this video presented to the XSEDE Advisory Board. 


XSEDE Organization Charts


XSEDE Access Ports

An XSEDE Access Port is an advanced computing resource made available to researchers via the XSEDE User Portal. The map below shows the national distribution of XSEDE access ports. 



Who is in each group?

Each L2 and L3 area has a wiki page that includes information about the work that team does as well as a list of staff members. Visit the Project Team Pages to find and learn about your WBS, which sub-group you are part of, who your Supervisor is, and who their supervisor or Director is. 


Key Points of Contact (PoCs)

We are in the process of compiling a list of Key Points of Contact to help answer any questions you may have which this guide has not sufficiently addressed. 


Onboarding Process for New Employees

Some WBS areas have defined their own New Staff Checklists. For example, WBS 2.2 ECSS has developed a specific New Staff Orientation for their group. 

XSEDE has created a New Staff Onboarding Form, which should be one of the first things for you and/or your Supervisor to complete. 

XSEDE Decision-Making Process

While XSEDE is a large and complex distributed organization, we have intentionally kept the decision-making process as streamlined as possible.
