ISC’14 Insights

July 10th, 2014

With ISC’14 in June recently concluded, the IBTA would like to highlight some of our members’ biggest announcements, key takeaways from the event and give an overall look at the impact of InfiniBand in the supercomputing world.

Event Overview

Overall the event was a huge success, showcasing demonstrations and facilitating many major announcements in the supercomputing industry. As always, the event attracted supercomputing leaders from around the world, who provided thought leadership and knowledge to thousands of attendees and exhibitors.

Chris Pfistner, senior director of marketing at Finisar, noted, “ISC in Leipzig is a vibrant show!  Between SC in the US and ISC focused on Europe and Asia, the global Super Computing community is well represented, and the space is on fire with several players unveiling new systems and showing great interest in Finisar’s EDR AOC demo – 100G links are becoming reality.”

The ISC YouTube channel is another great resource for checking out all that happened at ISC’14!

Major InfiniBand Announcements

During the event, the updated TOP500 list was released, showing that InfiniBand is the most used interconnect by the world’s fastest supercomputers and represents 44.4 percent of the TOP500 at 222 systems. InfiniBand also connects the top 17 most efficient systems and 50 percent of Petaflop-capable systems on the list. Fourteen Data Rate (FDR) InfiniBand, delivering 56Gb/s per link to address the bandwidth demand by high performance clustered computing, drives the systems with the highest utilization on the TOP500, achieving a record breaking 99.8 percent system efficiency.

IBTA member Finisar showcased a live demonstration of its next generation 100Gb/s Quadwire Active Optical Cable (AOC). This optical interconnect runs four parallel lanes of 25Gb/s to enable the next generation of InfiniBand EDR-based supercomputers. Leveraging Finisar’s patented fiber optic technology, the AOC will allow the transmission of high-speed data with enhanced signal integrity, higher density, lower power consumption, smaller bend radius and longer reach than traditional copper solutions.

Mellanox Technologies, also an IBTA member, unveiled the world’s first 100Gb/s EDR InfiniBand switch at ISC’14. The 100Gb/s switch expands InfiniBand’s bandwidth and provides increased switching capacity while lowering latency and power consumption. This solution, called Switch-IB, will enable application managers to use the power of data, delivering 5.4 billion packets per second, and making it an excellent solution for HPC, cloud, Web 2.0, database and storage centers.

In other news, Applied Micro teamed up with Nvidia to promote the X-Gene and Tesla duo. The Ethernet ports on the X-Gene 2 chip will be able to run RDMA over Converged Ethernet (RoCE), which brings the low latency of RDMA to the Ethernet protocol. This will make the chip not only suitable for HPC workloads that are latency sensitive, but also for database, storage, and transaction processing workloads in enterprise datacenters that also demand low latency. In tandem, Mellanox announced that their 56Gb/s InfiniBand products will now be optimized for the X-Gene platform.

To sum it all up, here are the IBTA’s key takeaways from the event:

· 100Gb/s is becoming a reality

· InfiniBand is leading the way with EDR taking center stage

· The industry is taking full advantage today of the performance and efficiency benefits of FDR and RoCE

ISC’14 was a great forum for knowledge sharing and big industry announcements. All of us at the IBTA look forward to seeing more InfiniBand news and discussions in the coming months.

Newest IBTA Compliance & Interoperability Testing Includes EDR 100Gb/s InfiniBand Methodology

February 25th, 2014

2014 has already proved to be a busy year for the IBTA. The organization is currently in the midst of compiling results from the recent Plugfest 24, which took place this past October at the University of New Hampshire’s Interoperability Laboratory.

IBTA SC13 Demonstration

While exhibiting at SC13 in November, we had the opportunity to showcase the IBTA’s newest EDR 100Gb/s compliance and interoperability testing capabilities that were implemented during October’s biannual Plugfest event. Due to the popularity of the demo at the conference, we wanted to share some details and results here on our blog.

The IBTA’s sophisticated test set-up leveraged Anritsu generators and Tektronix scopes to test EDR active cables.  The Anritsu generators were used to generate a spec compliant 25Gb/s input signal to one lane of an active optical cable along with 25Gb/s signals to the other 7 lanes which were being used as “aggressor” lanes.  Tektronix provided a scope capable of testing the 25Gb/s per lane output of the EDR active cables. The details are provided in the Anritsu Method of Implementation (MOI) which is available here:  http://infinibandta.org/content/pages.php?pg=technology_methods_of_implementation.

The significance of this testing, is that we were able to not only achieve 25Gb/s speed per lane (100Gb/s total over 4 lanes), but we were also able to analyze data at that speed. The IBTA currently has both copper and active optical cables running at 100Gb/s that are also compliant with the latest InfiniBand specifications.

3M Company, Advanced Photonics, Inc, Amphenol, FCI, Finisar, Foxconn, Fujikura Ltd., Hitachi Cable America, Lorom Industrial, Mellanox, Molex, Samtec, Sumitomo, TE Connectivity and Volex attended PlugFest 24 and tested a total of 189 cables for both compliance and interoperability.

Intel, Mellanox and NetApp also tested a total of 17 devices including InfiniBand to Ethernet Gateways, Host Channel Adapters (HCAs), Switches and SRP Targets. These end points and switches provided the foundation for running approximately 1000 interoperability tests using the Open MPI test benchmark and the interconnects provided by the cable vendors listed above.

Anritsu InfiniBand ATD EDR Test Solution

Agilent, Anritsu, Tektronix and Wilder Technologies all provided the latest generation of Test equipment needed to test 100Gb/s InfiniBand EDR cables. The IBTA PlugFest provides a great opportunity for all these companies to work together to improve InfiniBand and to ensure that the products are both robust and interoperable.

IBTA’s Plugfest events take place twice per year, during which the IBTA tests compliance with the InfiniBand architecture specification and interoperability with other InfiniBand products. The IBTA Plugfest 24 Integrators’ List has been released and features vendor devices and cables that successfully passed all required Integrators’ List compliance tests and interoperability procedures during Plugfest 24.

The IBTA Integrators’ List contains a list of compliant and interoperable products and is available here: http://infinibandta.org/content/pages.php?pg=integrators_list_overview.

IBTA Updates Integrators’ List Following PF23 Compliance & Interoperability Testing

September 25th, 2013

We’re proud to announce the availability of the IBTA April 2013 Combined Cable and Device Integrators’ List – a compilation of results from the IBTA Plugfest 23, during which we conducted the first-ever Enhanced Data Rate (EDR) 100Gb/s InfiniBand standard compliance testing.

IBTA’s updated Integrators’ List and our newest Plugfest testing is a testament to the IBTA’s commitment to advancing InfiniBand technology and ensuring its interoperability, as all cables and devices on the list successfully passed the required compliance tests and interoperability procedures. Vendors listed may now access the IBTA Integrators’ List promotional materials and a special marketing program for their products.

Plugfest 23 was a huge success, attracting top manufacturers and would not have been possible without donated testing equipment from the following vendors: Agilent Technologies, Anritsu, Molex, Tektronix and Wilder Technologies. We are thrilled with the level of participation and the caliber of technology manufacturers who came out and supported the IBTA.

The updated Integrators’ List is a tool used by the IBTA to assure vendors’ customers and end-users that manufacturers have made the mark of compliance and interoperability. It is also a method for furthering the InfiniBand specification. The integrator’s list is published every spring and fall following the bi-annual Plugfest and serves to assist IT professionals, including data center managers and CIOs, with their planned deployment of InfiniBand solutions.

We’ve already begun preparations for Plugfest 24, which will take place October 7-18, 2013 at the University of New Hampshire’s Interoperability Laboratory. For more information, or to register for Plugfest 24, please visit IBTA Plugfest website.
