Mellanox InfiniBand Leads TOP500 as Most Used Interconnect Technology for High-Performance Computing for the 2nd Consecutive Time

Mellanox InfiniBand is the most used interconnect for Petascale-performance systems

SC14, New Orleans, LA. – Nov. 18, 2014 Mellanox® Technologies, Ltd. (NASDAQ: MLNX), a leading supplier of end-to-end interconnect solutions for data center servers and storage systems, today announced that InfiniBand continued its leadership as the most deployed interconnect solution on the TOP500 list of supercomputers. The number of InfiniBand-based supercomputers increased 8.7 percent year-over-year to 225, representing 45 percent of the TOP500.  Mellanox InfiniBand is the interconnect of choice for Petascale computing Petaflop capable systems, connecting 24 Petascale-performance systems on the list. Overall, the number of Mellanox FDR InfiniBand connected systems grew 1.8X year-over-year connecting 141 systems, showing the increased demand for higher performance, scalability and efficiency.

Mellanox Connect-IB® and ConnectX®-3 FDR 56Gb/s InfiniBand adapters and SwitchX®-2-based switch systems optimize server and storage performance and provide the scalable, low-latency, and power-efficient interconnect for the world’s fastest supercomputers.  The advanced offloads and accelerations within Mellanox FDR 56Gb/s InfiniBand solutions enable the most performance-efficient systems on the TOP500 list with a record 99.8 percent system efficiency.

“We are excited to release 100Gb/s solutions that can enable the analysis, store, and retrieval of the growing amounts of data,” said Eyal Waldman, president and CEO of Mellanox Technologies. “Mellanox’s end-to-end InfiniBand solutions have become a critical element of enabling the most performance-efficient systems in the TOP500. We expect to continue our leadership in HPC and further our market penetration in the cloud and Web 2.0 markets. We look forward to working with our partners and customers to help businesses cope with the growth of data.”

Published twice a year and publicly available at, the TOP500 list ranks the world’s most powerful computer systems according to the Linpack benchmark rating system.
