PING Shaves Strokes Off Its Golf Club Design Cycle With a Cray XD1 Supercomputer
Company Uses Complex Simulations to Speed Design and Testing of Prototypes

SEATTLE, WA, Nov 07, 2005 (MARKET WIRE via COMTEX News Network) -- Global supercomputer leader Cray Inc. (NASDAQ: CRAY) today announced that leading golf equipment designer and manufacturer PING Inc. has made a Cray XD1(TM) supercomputer a critical part of its research and development program. Running Livermore Software Technology's LS-DYNA computer-aided engineering (CAE) software on the Cray XD1 system, PING has reduced the time needed to conduct preliminary structural tests of new club designs from weeks to mere hours. The Cray XD1 system employs a high-performance computing (HPC) architecture that allows designers to run larger, more detailed simulations with greater accuracy than was possible with a conventional engineering workstation.

By simulating golf club characteristics on the Cray supercomputer using finite element analysis (FEA) techniques, PING engineers can eliminate weak or ineffective designs before they move on to more expensive and time-consuming physical prototyping, which involves molding an actual club and testing it using a robotic golfer to precisely hit the balls. It generally takes the company about three to four weeks to produce a physical prototype.

PING tests new club designs on the supercomputer by creating a three-dimensional matrix that closely approximates how the equipment would perform in real life. The system can simulate the impact of a club head against a ball, the bending of the shaft during a stroke, the stability of a putter while in motion and other complex problems. With these capabilities, the PING design team can, for example, identify areas of low stress and virtually reposition weight to other areas of the club, increasing performance while maintaining the original balance and feel.

"PING is committed to ensuring that the innovations we design into our golf clubs result in solid improvements that make the game more enjoyable for our customers," said Eric Morales, staff engineer and FEA design analyst at PING. "With the Cray XD1 system, we can now run simulations in minutes that previously took several hours or even days on a generic workstation. The LS-OPT design optimization and probabilistic analysis package that we use to compute the best design features within specified parameters demands a complex simulation environment that can run jobs across multiple processors simultaneously. That level of computing would have been impossible on our previous system."

"The business advantages that PING will gain through virtual equipment prototyping showcases the power and versatility of the Cray XD1 system's purpose-built, high-performance design," said Himanshu Misra, CAE business manager at Cray. "PING demonstrates that the benefits of HPC are no longer confined to scientific and large-scale engineering organizations. Enterprises of many kinds are increasingly taking advantage of supercomputing to bring better products to market, increase productivity and sharpen their competitive edge in the marketplace."

About the Cray XD1 Supercomputer

The Cray XD1 supercomputer combines direct-connect system architecture, HPC-optimized Linux, management and reconfigurable computing technologies to deliver industry-leading performance on real-world applications. Purpose-built for demanding HPC applications such as computational chemistry, environmental forecasting and CAE, the Cray XD1 system lets users simulate, analyze and solve complex problems more quickly and accurately. The x86-based Cray XD1 system supports a broad range of 32- and 64-bit HPC applications on AMD Opteron single- or dual-core processors. The system also provides application acceleration capabilities using field-programmable gate array (FPGA) technology directly connected to the Cray XD1 compute environment.

" We're doing a lot of work with finite element. The results of that is in a lot of these clubs. We just ordered a new Cray Supercomputer so we don't have to wait 48 hours for the results on the finite element. We get it in about 15 minutes. The only problem is, when you run through a test like that, it takes 6 to 8 hours to set up for that run. This way more of our guys can be feeding that."
