Lenovo today 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 customized supercomputing
solution, designed to optimize 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, AT&T Williams. “The optimum balance of downforce and drag varies
between different circuits, so the aerodynamics 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 three-dimensional, 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 percent.
“Aerodynamics has been steadily gaining 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 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. |
