InfiniBand Most Used Interconnect on the TOP500

June 21st, 2012
The TOP500 list was released this week, ranking the fastest supercomputers in the world. We at the IBTA were excited to see that InfiniBand’s presence increased on the list to become the most used interconnect for the first time.  Clearly, InfiniBand is the interconnect of choice for today’s compute-intensive systems! As the chart below demonstrates, InfiniBand’s adoption rate has grown significantly, outpacing all of the other options.

We were also pleased to see that since the last report 6 months ago FDR has increased the number of systems it connects tenfold, making it the fastest growing interconnect on the list.  

The TOP500 list notes that InfiniBand connects eight of the 20 Petascale systems on the list, and that InfiniBand-connected systems boast the highest performance growth rates on the list.  Petascale systems on the TOP500 list favored InfiniBand because of its scalability and the resulting computing efficiency. The graph below illustrates the performance trends showing how supercomputing depends on InfiniBand to achieve the highest performance.

The TOP500 list demonstrates what the IBTA and the InfiniBand community have already known - InfiniBand is a technology that has changed the face of HPC and, we believe, is having the same effect on the enterprise data center. Below, are some additional stats referenced on the TOP500 list.

  • InfiniBand connects 25 of the 30 most compute-efficient systems, including the top 2
  • InfiniBand-based system performance grew 69% from June ‘11 to June ‘12
