Lenovo announced the successful installation of a powerful supercomputer for AT&T Williams, now being used in the racing team’s wind tunnel simulation facilities in the UK.
AT&T Williams and Lenovo collaborated on the customised supercomputing solution, designed
to optimise the aerodynamics of the team’s Formula One cars.
|“Aerodynamics plays a critical role in determining how competitive we are for each of the race circuits we visit,” said Alex Burns, Chief Operating Officer, Williams F1. “The optimum balance of downforce and drag varies between different circuits, so the aerodynamic challenges at Monaco -- lots of tight corners with few straights -- are very different from Monza, which has few corners but lots of long straights. The increase in supercomputing power from Lenovo will give us the capability to examine a greater range of design variations between races, which will increase our development rate, bringing more performance to the car sooner.”|
The supercomputer is being used for operations in Computational Fluid Dynamics (CFD), performing billions of calculations that simulate airflow around a virtual model of a threedimensional, on-track racing car. This process will help predict how even the smallest changes in component shape and placement will affect drag and downforce, with resulting impacts on speed and handling.
With a peak performance of eight teraflops (trillion floating point operations per second), the Lenovo supercomputer is four times more powerful than the team’s previous solution. This will enable the team to speed up the process of aerodynamic simulation by approximately 75%. “Aerodynamics has been steadily gaining in importance in recent years, accounting for roughly three quarters of the performance of a Formula One car today,” Burns said. “The tremendous increase in power delivered by the Lenovo supercomputer will allow us to perform the same tasks we do today in a quarter of the time.”
The team uses the supercomputer to examine numerous aerodynamic variables, such as surface geometry, wheel turbulence and track surface. For example, the team can analyze the effects of adjusting the curvature of the car’s surface, with the goal of improving the generation of downforce and the reduction of drag.
The aerodynamic simulations are being done in combination with experimental techniques in the team’s two wind tunnels. Computer-generated tests will enable the AT&T Williams team to focus resources on building the most promising solutions for testing in the wind tunnel and on track.
|“The high-performance computing solution developed for AT&T Williams is the latest example of Lenovo’s capabilities in world-class engineering and research,” said Deepak Advani, Senior Vice President and Chief Marketing Officer, Lenovo. “We’re excited about providing a supercomputing solution that delivers the power and speed necessary for AT&T Williams to stay competitive in the most technologically advanced sport in the world.”|
This agreement is an extension of the relationship between Lenovo and AT&T Williams. At the beginning of the 2007 race season, Lenovo announced its support as an Official Partner of AT&T Williams. The team uses Lenovo PC technology in every facet of its business, from ignition to inventory.
