FDR InfiniBand Continues Rapid Growth on TOP500 Year-Over-Year

November 22nd, 2013

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.

Visit the IBTA and OFA at SC13!

November 13th, 2013

Attending SC13? The IBTA will be teaming up once again with the OpenFabrics Alliance (OFA) to participate in a number of conference activities. The organizations will be exhibiting together at booth #4132 – stop by for access to:

  • Hands-on computing cluster demonstrations
  • IBTA cable compliance demonstration
  • IBTA & OFA member company exhibition map and SC13 news
  • Current and prospective member information
  • Information regarding OFA’s 2014 User Day and Developer Workshop

IBTA and OFA will also lead the discussion on the future of I/O architectures for improved application performance and efficiency during several technical sessions:

  • RDMA: Scaling the I/O Architecture for Future Applications,” an IBTA-moderated session, will discuss what new approaches to I/O architecture could be used to meet Exascale requirements. The session will be moderated by IBTA’s Bill Boas and will feature a discussion between top users of RDMA. The panel session will take place on Wednesday, November 20 from 1:30 p.m. to 3:00 p.m. in room 301/302/303.

  • Accelerating Improvements in HPC Application I/O Performance and Efficiency,” an OFA Emerging Technologies exhibit, will present to attendees ideas on how incorporating a new framework of I/O APIs may increase performance and efficiency for applications. This Emerging Technologies exhibit will take place at booth #3547. The OFA will also be giving a short talk on this subject in the Emerging Technologies theatre at booth #3947 on Tuesday, November 19 at 2:50 p.m.

  • OFA member company representatives will further develop ideas discussed in its Emerging Technologies exhibit during the Birds of a Feather (BoF) session entitled, “Discussing an I/O Framework to Accelerate Improvements in Application I/O Performance.” Moderators Paul Grun of Cray and Sean Hefty of Intel will lead the discussion on how developers and end-users can enhance and further encourage the growth of open source I/O software.
