Invitation to Submit Expressions of Interest for Joint Access to PRACE and XSEDE Resources by Collaborating Teams

Invitation to Submit Expressions of Interest

PRACE and XSEDE are major Research Infrastructures, providing peer reviewed access to high-end HPC resources and services in Europe and the US, respectively. PRACE and XSEDE have a very successful collaboration on joint organization of an annual HPC Summer School and we are now exploring options to extend our efforts to other activities that effectively support collaborating research teams spanning the US and Europe. This can include, but is not limited to the provisioning of interoperable services, and/or the issuance of a joint call for allocations requests which would annually award resources for a fixed period of 12 months to support projects that are judged to require them and to be able to utilize them to make significant advances in their fields.

The collaboration between PRACE and XSEDE builds on previous joint activities by DEISA and TeraGrid, which initiated the EU US Summer School.

The XSEDE Senior Management Team and the PRACE Board of Directors invite Expressions of Interest for such joint activities by PRACE and XSEDE to provide a better understanding of the level of demand, the scientific justifications and the best way to establish and structure solutions to support them.

Expressions of Interest should be submitted to or before 15 September 2012. They should be no longer than two pages and should address the following points.

  1. Identify the collaborating teams in Europe and the US.
  2. The scientific justification for suggested activity.
  3. The justification for access to resources in both the US and Europe, where applicable.
  4. The anticipated resource levels required.
  5. How the resources would be managed between the collaborators.
  6. Mechanisms for monitoring progress and reviewing outcomes.


PRACE The Partnership for Advanced Computing in Europe (PRACE) is an international non-profit association with its seat in Brussels. The PRACE Research Infrastructure (RI) provides a persistent world-class High Performance Computing (HPC) service for scientists and researchers from academia and industry. The Implementation Phase of PRACE receives funding from the EU’s Seventh Framework Programme (FP7/2007-2013) under grant agreements n° RI-261557 and n° RI-283493.The implementation phase of the PRACE projects receives funding from the European Union’s Seventh Framework Programme.

Xsede XSEDE is the most advanced, powerful and robust collection of integrated 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 partnership of more than a dozen institutions engaged in providing HPC resources, software, extended support, education, outreach, and training to help more scientists and engineers use the resources. The five-year project is supported by the National Science Foundation. XSEDE:

Closed Calls for Expressions of Interest

Feedback to those who have submitted Expressions of Interest for Programme Access in 2011

Based on its analysis of 17 Expressions of Interest, the SSC recommended to the 6th PRACE Council on 24 Jan 2012 that it opens calls for Multiyear Access, inviting applications of up to three years’ duration. These would be subject to the same peer-review criteria as applications for Project Access. Allocation of resources would be made one year at a time, with provisional allocations granted for future years. The total resources allocated to new Multiyear Access projects should not exceed 20% of the total resources available in any year (so that no more than 60% is allocated to Multiyear Access projects at any time). All Multiyear Access projects would be subject to full peer review annually, based on progress reports and revised plans, and allocations to them adjusted accordingly.

Council agreed to include a Test Call for Multiyear Access as part of the 5th Regular Call. The responses to this will be evaluated by the SSC and a further recommendation to Council will be required for this mechanism to be continued in further Calls.

Council and the SSC recognise that the combination of Preparatory, Project and Multiyear Access may not be sufficient to meet all requirements for access, e.g. for some ESFRI projects, but agreed that Multiyear Access be introduced before considering any further mechanisms. The terminology “Multiyear” rather than “Programme” was adopted for this mode of access to leave open the possibility of using the latter if a fourth mechanism is required.

The SSC would welcome further input regarding these access mechanisms.
