Intel’s AI-oriented processor
23 October 2017 | 0
There are a number of efforts involving artificial intelligence (AI) and neural network-oriented processors from vendors such as IBM, Qualcomm and Google. Now, you can add Intel to that list. The company has formally introduced the Nervana Neural Network processor (NNP) for AI projects and tasks.
This isn’t a new Intel design. The chips come out of Intel’s $400 million (€340 million) acquisition of a deep learning start-up called Nervana Systems last year. After the acquisition, Nervana CEO Naveen Rao was put in charge of Intel’s AI products group.
“The Intel Nervana NNP is a purpose-built architecture for deep learning,” Rao said in a blog post formally announcing the chip. “The goal of this new architecture is to provide the needed flexibility to support all deep learning primitives while making core hardware components as efficient as possible.”
He added: “We designed the Intel Nervana NNP to free us from the limitations imposed by existing hardware, which wasn’t explicitly designed for AI.”
That is an interesting statement, since Rao could be referring to the x86 architecture—or GPUs, since Nvidia’s CEO has never been shy about sniping at x86.
Rao did not go into design specifics, only that the NNP does not have a standard cache hierarchy of an x86, and on-chip memory is managed by software directly. He also said the chip was designed with high speed on- and off-chip interconnects, enabling “massive bi-directional data transfer.”
Self-learning in AI development
Intel CEO Brian Krzanich had his own blog post on the subject.
“Using Intel Nervana technology, companies will be able to develop entirely new classes of AI applications that maximise the amount of data processed and enable customers to find greater insights—transforming their businesses,” he wrote.
Krzanich also revealed that Facebook was involved in the design of the processor, although he did not elaborate beyond saying Facebook worked with Intel “in close collaboration, sharing its technical insights.”
Now, why would Facebook care? Because one of the potential uses for the NNP as described by Krzanich is in social media to “deliver a more personalised experience to their customers and offer more targeted reach to their advertisers.”
Neuromorphic chips are inspired by the human brain and designed to be self-learning, so as they perform a task they get better at it and look at new ways of executing it.
A recent documentary on the Japanese news channel NHK World illustrated that, where an AI application that practiced millions of games of shogi, a Japanese chess-like board game, came up with its own strategies that it had not been programmed into it, flabbergasting the developer and human player it roundly trounced. It thought for itself.
All of which calls to mind the famous line from Jurassic Park: “Your scientists were so preoccupied with whether or not they could, they didn’t stop to think if they should.”
