Why InfiniBand rules the roost in the TOP500

In this special guest feature, Bill Lee from the InfiniBand Trade Association writes that the new TOP500 list has a lot to say about how interconnects matter for the world’s most powerful supercomputers. “Once again, the List highlights that InfiniBand is the top choice for the most powerful and advanced supercomputers in the world, including the reigning #1 system – Oak Ridge National Laboratory’s (ORNL) Summit. The TOP500 List results not only report that InfiniBand accelerates the top three supercomputers in the world but is also the most used high-speed interconnect for the TOP500 systems.”

InfiniBand Powers World’s Fastest Supercomputer

Today the InfiniBand Trade Association (IBTA) announced that the latest TOP500 List results that report the world’s new fastest supercomputer, Oak Ridge National Laboratory’s Summit system, is accelerated by InfiniBand EDR. InfiniBand now powers the top three and four of the top five systems. The latest rankings underscore InfiniBand’s continued position as the interconnect of choice for the industry’s most demanding high performance computing (HPC) platforms. “As the makeup of the world’s fastest supercomputers evolve to include more non-HPC systems such as cloud and hyperscale, the IBTA remains confident in the InfiniBand Architecture’s flexibility to support the increasing variety of demanding deployments,” said Bill Lee, IBTA Marketing Working Group Co-Chair. “As evident in the latest TOP500 List, the reinforced position of InfiniBand among the most powerful HPC systems and growing prominence of RoCE-capable non-HPC platforms demonstrate the technology’s unparalleled performance capabilities across a diverse set of applications.”

InfiniBand Accelerates 77 Percent of New HPC Systems on the TOP500

“InfiniBand being the preferred interconnect for new HPC systems shows the increasing demand for the performance it can deliver. Its place at #1 and #4 are excellent examples of that performance,” said Bill Lee, IBTA Marketing Working Group Co-Chair. “Besides of delivering world-leading performance and scalability, InfiniBand guarantees backward and forward compatibility, ensuring users highest return on investment and future proofing their data centers.”

InfiniBand Continues Momentum on Latest TOP500

Today the InfiniBand Trade Association (IBTA) announced that InfiniBand remains the most used HPC interconnect on the TOP500. Additionally, the majority of newly listed TOP500 supercomputers are accelerated by InfiniBand technology. These results reflect continued industry demand for InfiniBand’s unparalleled combination of network bandwidth, low latency, scalability and efficiency.

As demonstrated on the June 2017 TOP500 supercomputer list, InfiniBand is the high-performance interconnect of choice for HPC and Deep Learning platforms,” said Bill Lee, IBTA Marketing Working Group Co-Chair. “The key capabilities of RDMA, software-defined architecture, and the smart accelerations that the InfiniBand providers have brought with their offering resulted in enabling world-leading performance and scalability for InfiniBand-connected supercomputers.”

RoCE Initiative Launches Online Product Directory

Today the RoCE Initiative at the InfiniBand Trade Association announced the availability of the RoCE Product Directory. The new online resource is intended to inform CIOs and enterprise data center architects about their options for deploying RDMA over Converged Ethernet (RoCE) technology within their Ethernet infrastructure.

InfiniBand Roadmap Foretells a World Where Server Connectivity is at 1000 Gb/sec

The InfiniBand Trade Association (IBTA) has updated their InfiniBand Roadmap. With HDR 200 Gb/sec technolgies shipping this year, the roadmap looks out to an XDR world where server connectivity reaches 1000 Gb/sec. “The IBTA‘s InfiniBand roadmap is continuously developed as a collaborative effort from the various IBTA working groups. Members of the IBTA working groups include leading enterprise IT vendors who are actively contributing to the advancement of InfiniBand. The roadmap details 1x, 4x, and 12x port widths with bandwidths reaching 600Gb/s data rate HDR in 2017. The roadmap is intended to keep the rate of InfiniBand performance increase in line with systems-level performance gains.”

Recent Topics in the IBTA… and a Look Ahead

Bill Magro from IBTA gave this talk at the OpenFabrics Workshop. “This talk discusses some recent activities in the InfiniBand Trade Association including recent specification updates. It also provides a glimpse into the future for the IBTA.” Bill Magro is an Intel Fellow and Intel’s Chief Technologist for HPC software. In this role, he serves as the technical lead and strategist for Intel’s high-performance computing software and provides HPC software requirements for Intel product roadmaps.”

OFA Workshop in Austin to Put Spotlight on InfiniBand and RoCE

“The OpenFabrics Alliance (OFA) workshop is an annual event devoted to advancing the state of the art in networking. The workshop is known for showcasing a broad range of topics all related to network technology and deployment through an interactive, community-driven event. The comprehensive event includes a rich program made up of more than 50 sessions covering a variety of critical networking topics, which range from current deployments of RDMA to new and advanced network technologies.”

New InfiniBand Architecture Specifications Extend Virtualization Support

“As performance demands continue to evolve in both HPC and enterprise cloud applications, the IBTA saw an increasing need for new enhancements to InfiniBand’s network capabilities, support features and overall interoperability,” said Bill Magro, co-chair of the IBTA Technical Working Group. “Our two new InfiniBand Architecture Specification updates satisfy these demands by delivering interoperability and testing upgrades for EDR and FDR, flexible management capabilities for optimal low-latency and low-power functionality and virtualization support for better network scalability.”

OrionX Reports Position InfiniBand as the Leading HPI Technology and Mellanox the Leading Vendor

“For now, InfiniBand and its vendor community, notably Mellanox appear to have the upper hand from a performance and market presence perspective, but with Intel entering the HPI market, and new server architectures based on ARM and Power making a new claim on high performance servers, it is clear that a new industry phase is beginning. A healthy war chest combined with a well-executed strategy can certainly influence a successful outcome.”
