Japanese electronics giant has a new processor for machine learning. Will anyone use it?

NEC claims new vector processor speeds data processing 50-fold

It seems more vendors are looking beyond the x86 architecture for the big leaps in performance needed to power things like artificial intelligence (AI) and machine learning. Google and IBM have their processor projects, Nvidia and AMD are positioning their GPUs as an alternative, and now Japan’s NEC has announced a vector processor accelerates that data processing by more than a factor of 50 compared to the Apache Spark cluster-computing framework.

The company said its vector processor, called the Aurora Vector Engine, leverages “sparse matrix” data structures to accelerate processor performance in executing machine learning tasks. Vector-based computers are basically supercomputers built specifically to handle large scientific and engineering calculations. Cray used to build them in previous decades before shifting to x86 processors. 

It fell out of favor as x86 closed the performance gap, but NEC has a series of supercomputers called SX that really up the ante. Each CPU in the new generation, SX-ACE, can crank out 256 gigaFLOPs of performance and address 1TB of memory, which is pretty powerful. 

NEC said it also developed middleware incorporating sparse matrix structures to simplify machine-learning tasks. The company said the middleware can be launched from Python or Spark infrastructures without special programming and in the same format as the machine-learning library.

NEC’s vector processors are aimed at processing large data sets and image analysis. It should be noted that GPUs are essentially vector processors in their own right, and there is a great deal more support for Nvidia and AMD GPUs than vendor-specific processors, although NEC reportedly made many modifications to the processing routines to speed things up. 

NEC said it compared a use case in which Spark was executed in a cluster of servers while its middleware ran on the company’s SX-ACE vector computer. Both platforms were running 64 cores in their clusters. 

NEC introduced the Aurora Vector Engine at the International Symposium on Parallel and Distributed Computing in Innsbruck, Austria.

In June, the company announced it was investing $10 million in an Indian data analytics center that will focus on growing demand in the region for Hadoop processing and storage
