FDR InfiniBand Continues Rapid Growth on TOP500 Year-Over-Year
The newest TOP500 list of the world’s most powerful supercomputers was released at SC13 this week, and showed the continued adoption of Fourteen Data Rate (FDR) InfiniBand – the fastest growing interconnect technology on the list! FDR, the latest generation of InfiniBand technology, now connects 80 systems on the TOP500, growing almost 2X year-over-year from 45 systems in November 2012. Overall, InfiniBand technology connects 207 systems, accounting for over 40 percent of the TOP500 list.
InfiniBand technology overall connects 48 percent of the Petascale-capable systems on the list. Petascale-capable systems generally favor the InfiniBand interconnect due to its computing efficiency, low application latency and high speeds. More relevant highlights from the November TOP500 list include:
- InfiniBand is the most used interconnect in the TOP100, connecting 48 percent of the systems, and in the TOP200, connecting 48.5 percent of the systems.
- InfiniBand-connected systems deliver 2X the performance of Ethernet systems, while the total performance supported by InfiniBand systems continues to grow.
- With a peak efficiency of 97 percent and an average efficiency of 86 percent, InfiniBand continues to be the most efficient of interconnects on the TOP500.
The TOP500 list continues to show that InfiniBand technology is the interconnect of choice for HPC and data centers wanting the highest performance, with FDR InfiniBand adoption as a large part of this solution. The graph below demonstrates this further:

Delivering bandwidth up to 56Gb/s with application latencies less than one microsecond, InfiniBand enables the highest server efficiency and is ideal to carry multiple traffic types (clustering, communications, storage, management) over a single connection. As a mature and field-proven technology, InfiniBand is used in thousands of data centers, high-performance compute clusters and embedded environments that scale from two nodes up to clusters with thousands of nodes.
The TOP500 list is published twice per year and recognizes and ranks the world’s fastest supercomputers. The list was announced November 18 at the SC13 conference in Denver, Colorado.
