Re: Intel to buy deep-learning startup Nervana Systems for at least $350M

Having done a technical review of what Nervana has to offer... Why Intel? My assumption, is that Intel will lease the chips + software, similar to the way HP, Dell, etc. Lease GPU machines. Nervana honestly woukd have been obsolete and dead pretty soon without this. I see this as an acuire-hire.

>> an acquire-hire. For $350 million is not an acquire-hire.

I thought so too. Until I saw the HN thread on the recent acquisition of Quip by Salesforce

Addendum from the bottom of the article :

Update: An earlier version of the story indicated the purchase price was more than $350 million, according to a source. Multiple investors told Recode the purchase price was significantly above that price, with one pegging it at $408 million.

They don't state flops because they don't do floats. The nervana chip has some weird fixed point format that they think works better for deep learning. I've heard similar noise out of Google (the other TPU company ...), so I wouldn't be surprised if we'll see the same in many of the specialized chips that people will build for deep learning.

I really don't think CUDA support is important for nervana's offering. They think of themselves as the Apples of deep learning - they want to offer an integrated stack from the chip all the way to the APIs. The way most people use deep learning you don't really need to know CUDA, you just need to use a library that is fast. So it's enough that nervana's engineers know how to write deep learning libs for their own chip. Furthermore I can't see Intel caring that much about CUDA support, since CUDA is owned by Nvidia.

What I've heard about the chip makes it sound really exciting. Many of the trade-offs in deep learning are different from the ones you do in graphics, so specialized hardware makes sense.

I figured Nervana was mostly dead if they were stuck at 28 nm I figured Intel was down and out in Santa Clara without a strong deep learning play That all changed today. Intel has been bouncing all over the place trying to break into deep learning. If they don't screw this up, they just found their way in IMO.

>I figured Nervana was mostly dead if they were stuck at 28 nm Why? Is there a competitor that has leveraged a more modern process technology?

Yep, NVIDIA. Nervana's dedicated ASIC will deliver 55 (mostly) int16 TOps in 2017. In contrast, the two Titan XP GPUs I bought last week for a total of $2400 deliver 44 such TOps. Next year, a single Volta GPU will deliver at least 36 so I saw no way for them to win on their own with NVIDIA's GPU roadmap merrily marching along since 2007.

However, getting access to Intel's fabs makes them a lot more interesting and competitive. It's not a slamdunk for Intel yet because they still have to incorporate this into their product line (anyone seen Altera's Stratix 10 yet? Because that was supposed to be 2014's 10+ TFLOP GPU killer), but it's a fantastic acquisition and I wish them the best.

The GP part stands for "something else than graphics". CUDA is not general purpose in the sense that a lot of types of computation and data movement results in terrible performance. You buy GPU accelerators for performance reasons.

Case in point, GPUs are standard (for now) for training DNNs, but the big server farms that actually do the scoring run on Xeons.

What happened to OpenCL?

Google has implemented their own deep learning chip with no CUDA support and its serving their purposes well. Why not another industry giant, Intel?

Google's TPU claims to have a >10x perf/w advantage over GPUs (they state competitors, but GPUs are the defacto standard) and thats frankly more important that raw throughput at scale.

If Intel can ape Nvidia at deep learning then it is a big growth opportunity for them.

Nothing per se. It's just that it lags far enough behind CUDA that unless you have a specific reason to avoid NVIDIA hardware there are very few pragmatic reasons to use it.
