Looking Back at ISC 2015 in Frankfurt

This blog post was authored by Sando Anoff, Finisar RSM.

Finisar was a participant at the recent ISC 2015 High Performance Conference and Tradeshow in Frankfurt, the premiere annual Supercomputing event in Europe. We set up a live demo of a 100 Gb/s Quadwire® active optical cable, which attracted a lot of attention. This product is based on our advanced in-house device technology and consists of four VCSELS operating at 25 Gb/s each on the transmit side and the corresponding PIN receivers on the receive side (all integrated in a single cable).

If you are a newcomer to the field of supercomputing, you might wonder what optical communication has to do with it, but the fact is that high-speed and low-latency communications have always been an essential part of high-performance computing designs, due to the huge amounts of information that need to be transmitted quickly and with a minimum of delay within the different parts of the system. For such demanding requirements, and except in cases where the distances covered are relatively short, optical transmission is the way to go. Another increasingly important factor, as the supercomputers get even larger, is power-efficiency, especially as the industry moves towards exa-scale computing. There were a whole range of interesting technologies on display at the show: IC’s placed in bubbling liquids, entire PCB’s submerged in barrels of fluid, etc. This trend towards energy efficiency may partly explain the considerable interest shown in our optical engines (Board-mount optical assemblies) that we had on display. These are compact, high-bandwidth optical interconnects that can be mounted directly onto a host board and reduce power consumption.

Something that really caught my eye as I wandered through the exhibition area was a booth that showed how a supercomputing infrastructure can be extended to encompass our globe. It allows an InfiniBand fabric – normally a short-range network used in supercomputers and data centers – to be securely extended via optical fiber over global distances. This was presented by a company called Obsidian Strategics and I was very pleasantly surprised when the friendly gentleman there pulled out the transceiver installed in his systems, and, lo and behold, it was from Finisar! That definitely made my day, not to mention the great conversation we had about sending huge chunks of data across transoceanic links at light speed!

So where do we go from here? The fastest supercomputer in existence today (Milky Way 2) is about 10 thousand million times faster than the first supercomputer that was built in 1964. I am certainly looking forward to the future as the industry pushes the envelope of what is possible.

ISC’14 Wrap-Up

This week’s blog post comes from Steffen Koehler, Finisar Senior Product Line Manager.

Finisar recently exhibited at ISC’14 in Leipzig, Germany. What a fantastic event to showcase our Optical Interconnect portfolio for HPC/supercomputer applications. For details about these high-performance optics products and our exciting live 100G Quadwire active optical cable demo at the show, click here to read the press release.


For those show attendees who stopped by to visit our booth and enter our raffle, we are excited to announce the winner: Filippo Mantovani of the Barcelona Supercomputing Center. Congratulations!

See you next time at ISC’15 in Germany.

A Trip to China and A Top500 Award for Quadwire

This week’s Lightspeed post comes from guest blogger Tony Pearson, Finisar’s Director of Product Marketing.

A “lightspeed” visit to China! It was a short journey of only 3 days, with two halves and a tale of two cities, separated by a virtual “Great Wall”. The first half: a visit to Shanghai, both the city and one of the jewels in the Finisar homegrown facility treasury. The second: to Tianjin (approx. 150km from Beijing) to visit Dawning Information Industry Company Ltd. and their Nebulae Supercomputer installation. The virtual “Great Wall” I refer to was simply the barrier thrown up by Mother Nature to domestic flight schedules – during rainy season in Beijing we are reminded that no matter how fast our communication solutions become…she’s still the boss! I’ll focus on two halves and the cities for this post, but I’m always happy to recount my travel stories to the interested in a future blog post.

Let me begin with an event that I was honored to attend at the Dawning manufacturing facility in June for those companies, including Finisar, who helped enable the world’s #2 supercomputer “Nebulae” as ranked by the 35th edition of the Top 500 supercomputer list. The event celebrated a milestone for Dawning as the #1 Supercomputer solution vendor in China and #2 in the world in terms of performance as ranked by the Top 500. Dawning further honored Finisar with a commemorative award for participation in Nebulae.

The Nebulae Supercomputer was at the center of the celebration with the event including a tour of Nebulae itself. The exciting thing for me, personally, was to see a supercomputer with over 120 server racks connected using Quadwire™ Active Optical Cables. This excitement only perhaps topped by the fact that these cables were designed and manufactured by Finisar at the very facility I visited the previous day.

Although not my first visit to China, this was my first visit to Shanghai and the Finisar Shanghai R&D and Manufacturing facility. Shanghai is truly a city in the fast lane, quite literally with some of the best kept and most functional highways I’ve seen in the world. With all eyes currently on the World Expo site located on the Huang Pu River running through the heart of downtown, this is a city in the same mold as Singapore, New York, London or Hong Kong, in my opinion, with a very cosmopolitan feel and population. With an infectious air of both maturity and optimism, this is a city that makes you want to keep coming back. The same is true of the Finisar Shanghai team and site in its newer location with a mix of both locally and globally educated talent, with a vast wealth of experience in the fiber optics business.

While this trip was focused on the high tech: high tech cities, high tech facilities, high tech computer solutions and high tech fiber optics, the real story here for me was about two Laws of Nature: “Bandwidth x Distance” limits combined with our relentless need for more information, pushing fiber solutions over longer distances now to our homes and to the Supercomputer in its most recent incarnation. And, then of course Mother Nature, who stamped her laws on my ability to move around China if not the data in the highly controlled environment of the Nebulae Supercomputer installation.
