Audi Selects Voltaire to Help Advance Auto Safety Standards With HP Supercomputer

June 30, 2008

BILLERICA, MASS. & HERZELIYA, ISRAEL – Voltaire Ltd., a provider of grid backbone solutions for data centers,announced that Audi has implemented Voltaire’s Grid Director switches as partof an HP supercomputer to advance Audi’s auto safety standards. This is theauto industry’s fastest supercomputer and is ranked No. 81 on the TOP500 listof the world’s fastest supercomputers, according to


Thehigh-performance computing system helps save days of computing time along withunnecessary costs for vehicle safety simulations. The use of VoltaireInfiniBand switches and software for the supercomputer’s cluster interconnectgreatly improves the simulation software’s performance, allowing for deeper andfaster analysis and decreasing the design time needed for new car models.

Audi’s29.184-teraflop (peak performance) system is based on HP Cluster Platform3000BL, a system built using 608 nodes supporting HP ProLiant BL460c serverblades connected by Voltaire Grid Director 9024 20 Gigabits/second (Gbps)double data rate (DDR) InfiniBand switches. The system uses ESI’s PAM-CRASH 2Gsimulation software to perform crash simulations for various Audi car models.

VoltaireGrid Director switches use 20 Gbps InfiniBand technology, which provides highbandwidth and very low latency to enhance the infrastructure and applicationperformance. The switches provide the throughput and scalability needed tocapture the full power of the servers to calculate the tremendous volumes ofdata generated during the simulation process. The HP supercomputer enables Audito run more model simulations overnight, thus ensuring an effective designprocess that enhances the analysis of the safety elements of its vehicles.

“Audi hasslashed days off the computing time required for vehicle safety simulationsthrough its HP high-performance computing system running on Voltaireswitches, lowering overall costs,” said Ed Turkel, manager, product andsolution marketing, Scalable Computing & Infrastructure, HP. “HP’soptimized clustered solutions for computer-aided engineering applicationsenable customers to run more complex simulations faster, speeding time toresult, and delivering tangible return on investment quickly.”
