Welcome to the page of the EGI-XSEDE collaboration



The goal of this collaboration is to identify and exchange best practices and solutions between the XSEDE and EGI e-infrastructures so they can operate more efficiently and they can better serve scientists in the U.S. and Europe. The collaboration is focussed on four areas:

  • Operation of e-infrastructure services
  • Cloud services for science and education
  • Champions to engage with new users
  • User support and support for joint use cases

Background information on XSEDE

The Extreme Science and Engineering Discovery Environment (XSEDE) is the most advanced, powerful, and robust collection of integrated advanced digital resources and services in the world. It is a single virtual system that scientists can use to interactively share computing resources, data, and expertise. XSEDE is a five-year, $121-million project supported by the National Science Foundation. It replaces and expands on the NSF TeraGrid project.

Background information on EGI

The European Grid Infrastructure (EGI) delivers integrated computing services to European researchers, driving innovation and enabling new solutions to answer the big questions of tomorrow. EGI is a federation of over 340 resource centres, set up to provide computing services and resources to European researchers and their international collaborators. EGI supports research collaborations of all sizes: from the large teams behind the Large Hadron Collider at CERN and Research Infrastructures in the ESFRI roadmap, to the individuals and small research groups that equally contribute to innovation in Europe.

Area 1: Operations

  • EGI: Tiziana Ferrari <>, Malgorzata Krakowian <>
  • XSEDE: Victor Hazlewood <>


  1. Organisational benchmarking - compare operational processes and services – so we can identify the good practices and learn these from each other
  2. Helpdesk and ticket procedures (e.g. Escalation processes)
  3. Resource monitoring
  4. Use the multi-infrastructure use cases to decide what should be changed in the infrastructures and on which side (Compchem and WeNMR)
  5. Integration of helpdesk and accounting to support communities that in the future will jointly use XSEDE and involve OSG for those communities like wenmr that will also consume OSG resources


The EGI Helpdesk is GGUS:
Authentication of users is based on X.509 certificates. All users with a valid certificate released by a IGTF CA can have read access to all tickets.
The report generator is the system we are using to collect statistics about usage, distribution of tickets, time to respond and solve tickets etc.
Plenty of documentation is available on-line:

Area 2: Cloud

  • EGI: David Wallom <>
  • XSEDE: David Lifka


  1. VMI preparation – collaboration on creating endorsed images of common software
  2. Identify questions that the technical support teams will have to be able to answer
  3. Hybrid cloud setup – internal cloud that is kept busy, outburst some load to external clouds when needed.

Area 3: Champions

  • EGI: Catherine Gater <>
  • XSEDE: Kay

Area 4: User support and use cases

  • EGI: Gergely Sipos <>
  • XSEDE: Sergiu Sanielevici <>, Suresh Marru <>


  1. Support the implementation of the use cases that have been submitted to the 'Collaborative Use Examples' call
    1. Computational Chamistry use case
    2. WeNRM use case
  2. Identify science gateways that would benefit from the integration with XSEDE and EGI resources, and facilitate the integration activities.
