Mellanox Maximizes Return on Investment for Engineering Manufacturing Designs

ConnectX InfiniBand and Simulation Software from ANSYS Accelerate Virtual Engineering Design While Significantly Reducing Product Development Costs

SANTA CLARA, CA, and YOKNEAM, ISRAEL – April 2, 2008 Mellanox® Technologies, Ltd. (NASDAQ: MLNX; TASE: MLNX), a leading supplier of semiconductor-based, server and storage interconnect products, today announced that InfiniBand-based clusters accelerate engineering productivity with software from ANSYS, Inc. while dramatically minimizing energy and system expenses. According to a recent performance evaluation using the new benchmark suite from ANSYS (which represents real-life workloads for engineering simulation), using InfiniBand may save tens of thousands of watts of power and thousands of dollars of spending by eliminating inefficient server CPU utilization resulting from I/O bottlenecks. At the same time, InfiniBand promotes optimum productivity and scaling. Engineering simulation is one of the larger market segments in high-performance computing and involved hundreds of thousands of server installations in 2007. According to IDC, the segment’s 2005-2010 compound annual growth rate (CAGR) is more than 12 percent.

“ANSYS customers will be very well served by the leading performance and scalability levels achieved with Mellanox ConnectX InfiniBand,” said Chris Reid, vice president, marketing at ANSYS, Inc. “The combination of InfiniBand and our engineering simulation software helps our customers get more value from their analysis process, resulting in improved time to market and reduced engineering costs.”

The performance evaluation was performed using FLUENT® software from ANSYS at the Mellanox Cluster Center using Mellanox ConnectX IB 20Gb/s InfiniBand adapters and the latest AMD quad-core Opteron CPUs. The results, available on the ANSYS Web site (, show that FLUENT technology scales almost linearly on multi-core cluster platforms when used with InfiniBand. Moreover, the tests emphasize the advantages of the InfiniBand interconnect in any size of cluster deployment, from two server nodes and beyond. In fact, InfiniBand-based clusters as small as three or four server nodes provide higher productivity than large-scale Gigabit Ethernet-based clusters.

The tests also showed that InfiniBand significantly reduces costs by speeding simulation time. When compared to Gigabit Ethernet results against the new benchmark suite from ANSYS, InfiniBand delivered up to a 40 percent increase in the number of simulations per day with only a two-server node system, an 80 percent increase with four server nodes, and almost a 150 percent increase with a seven-server node cluster. These results equate to a 60 percent savings in power costs and a 50 percent savings in system costs while maintaining the same or higher productivity. 

“Today’s multi-core clustered environments impose the highest demands for throughput and efficiency,” said Earl Stahl, vice president, software engineering at AMD. “Applications such as FLUENT software from ANSYS continue to demonstrate superior parallelism and scalability on AMD multi-core based clusters using Mellanox ConnectX InfiniBand interconnect technology.”

According to the testing, FLUENT software has shown almost linear scalability and the capability to take full advantage of the leading-edge multi-core platforms when using InfiniBand. InfiniBand has been proven to maximize available compute capabilities for application usage and enables efficient scaling of additional servers for increasing application productivity.

“InfiniBand is the only standard interconnect for clusters that provides the needed performance characteristics for the majority of high-performance applications, along with the ability to scale with multi-core platforms,” said Thad Omura, vice president of product marketing at Mellanox Technologies. “InfiniBand efficiency accelerates engineering design cycle time from months to days, and enables significant savings in cost and power consumption.”
