ESI Group product story

Airbag models now routinely take into account fluid-structure interactions and realistic interactions of the airbag with structures and occupants.
Audi has implemented the auto industry's fastest supercomputer to advance safety standards.
Crucial in optimising car safety, the new system is based on ESI Group's Pam-Crash 2G simulation software and an HP Cluster Platform 3000BL system, providing 15.36teraflop/s of computing performance for crash simulation models of Audi.
The supercomputer implementation places the premium car manufacturer at number 123 on the top 500 list of the world's fastest supercomputers, making it the auto industry's fastest system.
Audi partnered with ESI Group to establish and drive its global vehicle safety projects around the world.
Audi recognised the unparalleled computing efficiency and ease of use of the Pam Crash 2G software and, as a result, the implementation improved the reliability of its crash safety and impact simulations.
The software enhancements combined with compact, fast and power-efficient HP hardware have enabled Audi to run its refined models overnight, ensuring an effective design process that includes analysis of the safety elements of its vehicles.
The ease of use and latest algorithms in the Pam-Crash 2G software encouraged Audi to raise their expectations for simulation design.
For example, airbag models now routinely take into account fluid-structure interactions and realistic interactions of the airbag with structures and occupants.
Furthermore, prediction testing for material rupture, which usually requires high resolution models, can now be treated using a multiscale approach.
This helps save days of computing time and unnecessary costs.
Audi selected HP to implement technology that would provide enhanced reliability, high server density and computing power.
Audi installed the HP Cluster Platform 3000BL, a system built using 320 nodes based on HP ProLiant BL460c server blades and the InfiniBand cluster interconnect.
This HPC system provides the computing power and speed needed to calculate the tremendous volume of data generated during the simulation process.
With the HP BladeSystem c-Class architecture coupled with the HP Dynamic Smart Cooling management solution, this supercomputer requires a quarter less floor space and consumes a quarter less power than a traditional rack-based configuration.
In addition, the blade configuration provides simple hardware maintenance, cabling and system administration and has outstanding scalability.
"Providing Audi with a high-performance computing solution helps them design better and safer cars while reducing their power consumption and costs", said Paul Perez, Vice President, High-Performance Computing, HP.
