TOP500 Interconnect Trends
TOP500.org released the list of the 500 most powerful commercially available computer systems in the world, reporting that InfiniBand powers 257 systems, 51.4 percent of the list. This marks a 15.8 percent year over year growth from June 2014.
Demand for higher bandwidth, lower latency and higher message rates along with the need for application acceleration is driving continued adoption of InfiniBand in traditional High Performance Computing (HPC) as well as commercial HPC, cloud and enterprise data centers. InfiniBand is the only open-standard I/O that provides the capability required to handling supercomputing’s high demand for CPU cycles without time wasted on I/O transactions.
- InfiniBand powers the most efficient system on the list with 98.8% efficiency.
- EDR (Enhanced Data Rate) InfiniBand delivers 100Gbps and enters the TOP500 for the first time, powering three systems.
- FDR (Fourteen Data Rate) InfiniBand at 56Gbps continues to be the most used technology on the TOP500, connecting 156 systems.
- InfiniBand connects the most powerful clusters, 33 of the Petascale-performance systems, up from 24 in June 2014.
- InfiniBand Is the leading interconnect for accelerator-based systems covering 77% of the list.
Not only is InfiniBand the most used interconnect solution in the world’s 500 most powerful supercomputers, it’s also the leader in the TOP100 as well. The TOP100 encompasses the top 100 supercomputing systems, as ranked in the TOP500. InfiniBand is the natural choice for world-leading supercomputers because of its performance, efficiency and scalability.
