Service Provider Forum

The national cyberinfrastructure ecosystem is powered by a broad set of Service Providers (SP). The XSEDE Federation primarily consists of SPs that are autonomous entities that agree to coordinate with XSEDE and each other to varying degrees. The XSEDE Federation may also include other non-service provider organizations.

Service Providers are projects or organizations that provide cyberinfrastructure (CI) services to the science and engineering community. In the US academic community, there is a rich diversity of SPs, spanning centers that are funded by NSF to operate large-scale resources for the national research community to universities that provide resources and services to their local researchers. The Service Provider Forum is intended to facilitate this ecosystem of SPs, thereby advancing the science and engineering researchers that rely on these cyberinfrastructure services. The SP Forum provides:

  • An open forum for discussion of topics of interest to the SP community.
  • A formal communication channel between the SP Forum members and the XSEDE project.

SPs are classified as being at a specific level by meeting a minimum set of conditions.They may meet additional conditions at their option, but classification at a specific level will be based on the stated required minimum conditions.

Briefly, Level 1 SPs meet all the XSEDE integration requirements and will explicitly share digital services with the broader community. Level 2 SPs make some digital services accessible via XSEDE and Level 3 SPs are the most loosely coupled; they will share the characteristics of their services via XSEDE, but need not make those services available beyond their local community. For more detailed descriptions, see the documents linked below.

XSEDE's Peer Institutions

XSEDE also needs to interact with other XSEDE-like organizations as peers. There are already such examples both within the United States and internationally.

Current international interactions include:

  • Partnership for Advanced Computing in Europe (PRACE) – Memorandum of Understanding (MOU)
  • European Grid Infrastructure (EGI) - Call for Collaborative Use Examples (CUEs)
  • Research Organization for Information Science and Technology (RIST) – Memorandum of Understanding (MOU)
