Life in the Fast Lane: InfiniBand Continues to Reign as HPC Interconnect of Choice

July 8th, 2016

top500

TOP500.org recently released its latest account of the world’s most powerful supercomputers and, as with previous reports, InfiniBand leads the way. The 47th edition of the bi-annual list shows that 205 of the fastest commercially available systems are accelerated by InfiniBand and OpenFabrics Software (OFS).

The InfiniBand fabric, with the OFS open source software, is the High Performance Computing (HPC) interconnect of choice because it delivers a distinctive combination of superior performance, efficiency, scalability and low latency. InfiniBand is the only open-standard I/O that provides the capability required to handle supercomputing’s high demand for CPU cycles without time wasted on I/O transactions. With today’s supercomputers pushing nearly 100 petaflops on the LINPACK benchmark, the need for efficient, low latency performance is higher than ever.

High Marks for InfiniBand and OFS

  • InfiniBand and OFS systems outperformed competing technologies in overall efficiency, scoring an 85 percent list average for compute efficiency – with one system even reaching an incredible 99.8 percent.
  • The technologies enable 70 percent of the HPC system segment. This segment includes academic, research and government fields.
  • For supercomputers capable of Petascale performance, the number of InfiniBand and OFS systems grew from 33 to 45.

InfiniBand’s ability to carry multiple traffic types over a single connection makes it ideal for clustering, communications, storage and management. As a result, the interconnect technology is used in thousands of data centers, HPC clusters, storage, and embedded application that scale from two nodes to a single cluster of tens-of-thousands of nodes. Supercomputers powered by OFS reach their highest performance capacity through the speed and efficiency delivered by Remote Direct Memory Access (RDMA). In turn, OFS enables RDMA fabrics, such as InfiniBand, to run applications that require extreme speeds, Petascale-level scalability and utility-class reliability.

Plugfest 28 Results Highlight Expanding InfiniBand EDR 100 Gb/s & RoCE Ecosystems

March 21st, 2016

il-interopWe are excited to announce the availability of our latest InfiniBand Integrators’ List and RoCE Interoperability List. The two lists make up the backbone of our Integrators’ Program and are designed to support data center managers, CIOs and other IT decision makers with their planned InfiniBand and RoCE deployments for enterprise and high performance computing systems. To keep data up to date and as useful as possible, both documents are refreshed twice a year following our bi-annual plugfests, which are held at the University of New Hampshire InterOperability Lab (UNH-IOL).

Having recently finalized the results from Plugfest 28, we can report a significant increase in InfiniBand EDR 100 Gb/s submissions compared to the last Integrators’ List. This trend demonstrates a continued industry demand for InfiniBand-based systems that are capable of higher bandwidth and faster performance. The updated list features a variety of InfiniBand devices, including Host Channel Adapters (HCAs), Switches, SCSI Remote Protocol (SRP) targets and cables (QDR, FDR and EDR).

Additionally, we held our second RoCE interoperability event at Plugfest 28, testing 10, 25 and 40 GbE RNICs, Switches and SFP+, SFP28, QSFP and QSFP28 cables. Although a full spec compliance program is still under development for RoCE, the existing interoperability testing offers solid insight into the ecosystem’s robustness and viability. We plan to continue our work creating a comprehensive RoCE compliance program at Plugfest 29. RoCE testing at Plugfest 29 will include testing of more than 16 different 10, 25, 40, 50 and 100 GbE RNICs and Switches along with all of the various cables to support these devices. Plugfest 29 testing of RoCE products, which use Ethernet physical and link layers, will be the most comprehensive interoperability testing ever performed.

As always, we’d like to thank the leading vendors that contributed test equipment to IBTA Plugfest 28. These invaluable members include Anritsu, Keysight Technologies, Matlab, Molex, Tektronix, Total Phase and Wilder Technologies.

The next opportunity for members to test InfiniBand and RoCE products is Plugfest 29 is scheduled for April 4-15, 2016 at UNH-IOL. Event details and registration information are available here.

InfiniBand Volume 1, Release 1.3 – The Industry Sounds Off

May 14th, 2015

spec-roadmap

On March 10, 2015, IBTA announced the availability of Release 1.3 of Volume 1 of the InfiniBand Architecture Specification and it’s creating a lot of buzz in the industry. IBTA members recognized that as compute clusters and data centers grew larger and more complex, the network equipment architecture would have difficulty keeping pace with the need for more processing power. With that in mind, the new release included improvements to scalability and management for both high performance computing and enterprise data centers.

Here’s a snap shot of what industry experts and media have said about the new specification:

“Release 1.3 of the Volume 1 InfiniBand Architecture Specification provides several improvements, including deeper visibility into switch hierarchy, improved diagnostics allowing for faster response times to connectivity problems, enhanced network statistics, and added counters for Enhanced Data Rate (EDR) to improve network management. These features will allow network administrators to more easily install, maintain, and optimize very large InfiniBand clusters.” - Kurt Yamamoto, Tom’s IT PRO

“It’s worth keeping up with [InfiniBand], as it clearly shows where the broader networking market is capable of going… Maybe geeky stuff, but it allows [InfiniBand] to keep up with “exascales” of data and lead the way large scale-out computer networking gets done. This is particularly important as the 1000 node clusters of today grow towards the 10,000 node clusters of tomorrow.” - Mike Matchett, Taneja Group, Inc.

“Indeed, a rising tide lifts all boats, and the InfiniBand community does not intend to get caught in the shallows of the Big Data surge. The InfiniBand Trade Association recently issued Release 1.3 of Volume I of the format’s reference architecture, designed to incorporate increased scalability, efficiency, availability and other functions that are becoming central to modern data infrastructure.” - Arthur Cole, Enterprise Networking Planet

“The InifiniBand Trade Association (IBTA) hopes to ward off the risk of an Ethernet invasion in the ranks of HPC users with a renewed focus on manageability and visibility. Such features have just appeared in release 1.3 of the Volume 1 standard. The IBTA’s Bill Lee told The Register that as HPC clusters grow, ‘you want to be able to see every level of switch interconnect, so you can identify choke-points and work around them.’” - Richard Chirgwin, The Register

IBTA Announces New RoCE Specification

September 16th, 2014

Big news! The IBTA today announced the updated specification for Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE), RoCEv2. This is a huge development and one that will expand RoCE’s adoption.

The benefits of the first RoCE spec released in 2010 were many:

  • Low latency and CPU overhead (eliminated the multiple data copies inside the server)
  • High network utilization
  • Support for message passing, sockets and storage protocols
  • Supported by all major operating systems

RoCEv2 extends the original RoCE specification by enabling routing across Layer 3 networks and as a result provides better isolation and enables hyperscale data center deployments. This addresses the needs of today’s evolving data centers which require more efficient data movement over a variety of network topologies.

With a number of vendors including Dell and Zadara Storage recently adopting RoCE, this new specification comes at the perfect time. Major cloud providers and Web 2.0 companies are also adopting RoCE in order to combat the challenges of running compute intensive applications and processing massive amounts of data in hyperscale networking environments.

Representatives from IBTA member companies including Emulex, IBM, Mellanox, Microsoft and Software Forge, Inc. participated in the development of this new standard, which will help enterprises to more widely adopt RoCE and improve infrastructure efficiency.

For more information, read the full IBTA announcement.

Recent Trends toward RoCE Adoption

September 2nd, 2014

The RoCE specification was released back in April, 2010 to address the need for efficient RDMA in end to end Ethernet networks. With the increase in enterprise data traffic and the emergence of hyperscale infrastructure, the need for efficient networking continues to grow.  Here are the latest examples of RoCE in the field.

RoCE Accelerates Microsoft Windows Azure

Albert Greenberg, an architect with IBTA member Microsoft, describes in his keynote address to the Open Network Summit this year how they are using RoCE in their storage offering.  RoCE over 40GbE enabled line-rate performance with zero CPU usage.  At the same time they were able to use less CPUs than would otherwise be needed.

RoCE Used in Dell Fluid Cache for SAN pool

Dell’s Fluid Cache for SAN accelerates applications requiring high data I/O. The servers in this pool are connected to each other by RoCE NICs, making use of the technology to quickly move data between the nodes without facing bottlenecks from the slow operating system kernel.

RoCE Can Do What Ethernet Alone Cannot

IBTA member Applied Micro is continuing to roll out its X-Gene family of 64-bit processors. These processors support RoCE, giving 10GbE some of the low-latency capabilities that used to only be available to InfiniBand. The decrease in latency for Ethernet means transaction latencies also decrease, better positioning the X-Gene family to make a difference in modern workloads.

RoCE Provides Exceptional Performance for Storage Solutions

Zadara Storage announced a new high performance STaaS solution offer for private clouds that uses an Ethernet transport mechanism for exceptional performance at reduced costs. Developed as a collaboration with IBTA member Mellanox Technologies, this solution boosts application performance using the iSCSI Extensions for RDMA (iSER) over RoCE, delivering substantially improved latency and throughput and therefore delivering cost savings and converged enterprise storage for private clouds of all sizes.

RoCE Helps Data Centers Account for New Technology for the Cloud

With the huge acceleration of data centers to the cloud, low latency is becoming increasingly important to avoid bottlenecks and incorporate new technologies seamlessly. RoCE, says SYS-CON Media’s Barbara Porter, is one way to plan for the barrage of new technology that’s coming our way, and to reduce latency overall in the cloud.
