InfiniBand™ is seeing continued growth on the TOP500 list, which serves as a precursor to commercial high performance computing (HPC) adoption. For the November 2010 list, InfiniBand represents more than 43 percent of all systems. InfiniBand was used by almost 46 percent of the TOP500 sites. InfiniBand connects the majority of the top 100 with 61 percent, the top 200 with 58 percent and the top 300 with 51 percent.
The total number of InfiniBand-connected CPU cores on the TOP500 list has grown 65 percent, from 1.4 million in Nov. 2009 to 2.3 million in Nov. 2010. InfiniBand connects the majority of the Petaflop systems on the Top10 with four out of seven.
With 96 percent system efficiency, InfiniBand is the only non-proprietary, open-standard I/O that provides the interconnect technology required to handle supercomputing’s high demand for CPU cycles without time wasted on I/O transactions. InfiniBand is the most efficient I/O used for inter-server communication in the TOP500.
Below is a breakdown of the November 2010 TOP500 list as the data relates to InfiniBand.
Performance of the systems on the TOP500 list has increased by a factor of 10 every five years.
The TOP500 performance increase of the years is being driven by the use of cluster system, which now represent 82.8 percent of the list.
InfiniBand is becoming the preferred HPC cluster interconnect with 43 percent of the TOP500 list currently using InfiniBand. Use of InfiniBand on the TOP500 is now approaching that of Gigabit Ethernet.
InfiniBand now enables almost 46 percent of all systems on the TOP500 list, compared to Gigabit Ethernet's 20 percent.
