SCIENCE

The PRACE Research Infrastructure featured, in the third PRACE regular call, a new system codenamed HERMIT that is installed at HLRS, Stuttgart provided by the Gauss Centre for Supercomputing in Germany. In addition to this, the Thin Node partition of CURIE made available by GENCI and operated at CEA, Bruyères-Le-Châtel, France was included, adding capability to the PRACE Research Infrastructure (RI). HERMIT is the third Tier-0 system in the PRACE RI after JUGENE (GCS) and CURIE (GENCI). The number of PRACE systems will continue to grow and provide more capacity and services to the European communities.

A total of 53 applications requesting 1.687 million compute core hours were received in this 3rd regular call, for one year resource allocations on the PRACE Research Infrastructure. The projects were chosen for their high level of scientific and technical maturity, expected impact, and demonstrated need for Tier-0 resources.

The projects are from the following scientific areas: astrophysics, chemistry and material science, medicine and life sciences, engineering and energy, fundamental physics and mathematics. All proposals underwent a peer review process governed by the PRACE Access Committee including PRACE technical assessment.

The following twenty-four projects, in alphabetical order, were awarded access to PRACE RI resources. More information on the projects and the corresponding awarded time is available at http://www.prace-ri.eu/hpc-access.

New call to be published on November 2nd 2011 The PRACE Research Infrastructure will open the next of its bi-yearly calls for Project Access on November 2nd, 2011. The computing resources for this call are available from May 2012 to April 2013. The new call will feature additional Tier-0 systems with new computing architectures, with 970 million core hours available. In addition, the new call will have no eligibility restrictions on the nationality of the principal investigators except for the restrictions imposed by the PRACE HPC centers.

Please visit the web page on November 2nd, 2011 for complete details on the call.
