Mellanox, Dell, Intel and LSTC jointly announced some new performance numbers today for the LSTC LS-DYNA crash code. LS-DYNA is commonly used in automotive crash simulation and was the major focus of this benchmark. [you can certainly use it for other finite element analysis, but crashing stuff is more fun].
The LS-DYNA 3-Vehicle Collision benchmark was run on Dell PowerEdge M610 blades with Intel Xeon X5670 processors. The interconnect was provided by Mellanox ConnectX-2 quad data rate Infiniband and an IS5030 36-port switch. Results from 48-core and 96-core sizes show that the combined solution delivers the world-leading performance versus any given system at these sizes, or versus larger core count systems based on Ethernet or proprietary interconnect solution based supercomputers.
Decreasing the time it takes to simulate car crashes provides auto manufacturers with faster time-to-market and less cost associated with the overall design phase,” said John Monson, vice president of marketing at Mellanox Technologies. “These benchmark results are a clear indication of the performance benefits of our end-to-end 40Gb/s InfiniBand networking products and the overall return-on-investment they bring to the automotive engineering community.”
LS-DYNA is widely used in the automotive industry for crashworthiness, occupant safety and metal forming, as well as for aerospace, military and defense and consumer products,” said Dr. Wayne Mindle, Sr. Engineer, at LSTC. “These benchmarks significantly show that engineers and designers in many industries can gain world-leading simulation performance benefits when running LS-DYNA on top of Intel-based Dell servers with Mellanox 40Gb/s InfiniBand networking.”
The performance testing was conducted at the HPC Advisory Council High Performance Center. For more info on their tests, read the full release here.
