Key figures about the 2013 campaign

  • More than 1 billion core hours applied for

  • 739 million core hours awarded to 571 projets

  • Selectivity more important (7 % rejection)

The commissioning of the Ada and Turing computer resources at Idris in Orsay at the beginning of 2013 increased the number of core hours available, but the pressure remains high.

  • Demand growing faster than supply

The average number of core hours applied for has increased from 811,000 in 2009 to 1.7 million in 2013. There were also more projects that called for more than 1 million hours: Over 100 in 2013 against 44 in 2010.

  • Very high level of pressure

  • Constantly growing

  • Even greater pressure in 2014

Whilst the pressure on Ada and Turing held at a reasonable level in 2013 because of their newness, it was very high for all the other machines, in particular for generalist ones. And, looking at the results sor far, the pressure continues to grow in 2014.

  • Multidisciplinary computing resources

  • Complementarity at the regional and national levels

As can be seen in the breakdown by major disciplines (subject panels or "comités thématiques" in French) here on the left, all French scientific communities are making use of the national computing resources.

27 % of projects also have access to computing hours at regional computing centres (so-called mesocentres).

  • Continuous renewal

More than a quarter (27 %) were new projects in 2013


  • Number of projects supported by the ANR (38%) and by companies (14%) held steady for two years


  • Efficient use of resources

This takes the specific form of the creation by GENCI of system to recover unused hours - with monthly alerts - aimed at promoting regular use by large projects throughout the year.


  • 48 projects at preparatory access stage

As of the beginning of 2013, French researchers have been able to request, using a quick and simple procedure, access to a small number of hours for migrating or testing their codes on new architectures. The request are assessed on the basis of technical criteria by computing centres, which can seek scientific advice as may be required.


  • Increasing parallelisation accrue

13% of codes (compared with 11% in 2012 and 7% in 2011) use more than 1,000 computing cores: They are ready for PRACE.


  • Availability rate in excess of 95%

  • Optimisation of computers workloads

  • Computers used to maximum capacity
