Formula 1 slows down on HPC

F1-2015-CFD-(Photo-Ansys)The world Motor Sport Council of the FIA has published regulation 2015 the formula 1 World Championship. In order to save several teams on the razor’s edge, the FIA wants to cut costs.
Among the measures taken, the teams will have to restrict their tests in a wind tunnel, but also their use of supercomputers. The use of the calculation intensive is one of the keys to performance in F1 but the FIA wants to stop the escalation of the power.

What more complex as a settlement of formula 1 Championship?

WT < = WT_limit (1 – CFD/CFD_limit)
with WT = Wind one Time,.
WT_limit = 30 hours
CFD = use of Teraflops for the CFD
and CFD_limit = 30 Teraflops.
This is the formula that governs the use of the blower and the compute-intensive by the stables of formula 1 this year. A formula to change slightly for the next season. The stables will be reducing their ambitions: the power (CFD_limit) will increase from 30 to 25 Teraflops and time of use of the power Venter (WT_limit) descended from 30 to 25 hours per week.

In F1, the HPC is not enough

The formula for calculating implementation by FIA limit so both the use of wind tunnels, with supercomputers but also imposes on the stables to find a balance between these two disciplines to develop the best aerodynamics for their cars. In 2010, Richard Branson created Virgin Racing stable in relying only on the high-performance computing. Numerical simulations type CFD (Computational fluid dynamics / fluids mechanics calculations) before landing the absence of wind tunnel. The results were calamitous. F1 teams perform so thousands of numerical simulations on their supercomputers, before some wind-tunnel test and then finally to send their productions on the track crossing my fingers that it works as initially calculated. A process which is still not free of errors and false leads. The drivers of the Lotus F1 2014 can attest. With its double nose, she is probably very powerful simulation and wind tunnel, but she doesn’t take off the tail of classification in the race. By 2015, the stables must better use their wind tunnels and their calculators to find the ultimate performance.
