This week the Hot Interconnects conference kicked off with a keynote by John Roese, VP and General Manager of Futurewei, Huawei’s North American R&D organization. After the talk, I got a chance to catch up with Rouse and ask him about the keynote and where Huawei is headed in the HPC space.
insideHPC: At the start of your keynote today, you described Huawei as “the largest company no one has ever heard of” with $32 Billion of telecommunications revenue in 2011. What was your message today for these engineers at the Hot Interconnects Conference?
John Roese: There were a lot of things, but the big message was that with all the things going on out there, whether they be cloud, virtualized services, or mobility, these are all things that we’ve seen before. Given our audience with a lot of deep expertise here, the fundamental point I wanted to make them was the they need to recognize the patterns. We have tried to solve these problems before. We have tried distributed environments. We have gone towards making the network transform itself, successfully, many times.
Through each of these evolutions, we learned lessons. We’ve learned that QoS when it’s overengineered doesn’t work, so make it simple. We’ve learned that no matter what you think about the predictability of the outcome and how the network is supposed to operate, it never really operates that way.
We’ve learned that if you make assumptions about symmetry and how traffic is going to flow or how a surge is going to be used, it usually reverses itself midstream and the water flow comes back at you. It surprises you.
So my number one point was to get these people, who are working on some really important things right now, to pause for a second and remember the lessons that they’ve learned so that we don’t repeat our old mistakes in the Cloud era.
insideHPC: So would you agree with the notion that there are no new problems, just new engineers working on old problems?
John Roese: I totally agree with that. For this audience at least, everyone has been in the industry for 10, 15, or 20 something years, they don’t have that excuse.
insideHPC: Earlier today you mentioned working with the folks at CERN on openlab. What are your thoughts on HPC at Huawei?
So obviously HPC is a technology area that’s used in many industries, whether it be large-scale data processing, research environments, and many different places where you use those techniques. The three main characteristics of an HPC environment are massive distributed compute capacity, massive storage capacity that is, in general, very cost-effective at enormous scales, and a huge amount of bandwidth consumption.
In the Huawei world, we don’t see HPC as a target market that we would building technologies exclusively just for that. Everyone of those things I just described could be applied to 10 other market domains. Let’s just take a look at those three.
For the massive network capacity, whether it be HPC or the backbone of a carrier or the core of a cloud infrastructure, we just launched a whole set of products that are 96 ports of 100 GigE on a single device. Why? Because people want a lot of bandwidth. When we give them a bandwidth step, they use it all.
We’re pretty excited about those types of technologies in the HPC environment. It gives you a low-cost, high-capacity, different bandwidth step and extremely high density in a single platform.
