Code_Saturne is freely vailable available to the UK research community on the supercomputers of the Science and Technology Facilities Council. (HPCx : IBM, 2,560 processors, and HECTOR: Cray XT4, 11,328 cores).
The gold status means that anyone using the code will get up to 30% discount on the CPU hours used depending on the number of nodes. Here is how the awards are given:
Bronze award: code must run at least 1.7 times faster on 256 processors (8 LPARs) than on 128 processors (4 LPARs), i.e. T128 / T256 ≥ 1.7.
