Started in 1993, the TOP500 lists the fastest computers used today, ranked according to Linpack benchmark results. Published twice a year, the TOP500 list provides an important tool for tracking usage trends in high-performance computing. The 44th TOP500 List was released during the SC'14 conference.

TOP500 44th List Highlights

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.
