Although the company isn’t yet ready to talk speeds and feeds, this week they did divulge some of their design decisions that they believe will make the Xeon Phi coprocessor shine as an HPC accelerator. The new revelations were presented on Tuesday at the IEEE-sponsored Hot Chips conference in Cupertino, California.
Intel refines Knights Corner design as it prepares to go head-to-head against its GPU competition.

The company also released a few more details about the upcoming product line, including the creation of a new Xeon brand for the architecture, some performance updates on pre-production silicon, and Cray’s adoption of MIC as part of its future Cascade supercomputer.

Also released were a number of documents describing the processor’s micro-architecture, including the Knights Corner Instruction Set (ISA) Manual, which will help toolmakers and application developers build software for the upcoming chip.

The meeting showcased the experiences of researchers who had ported their scientific computing codes to Intel’s Knights Ferry software development platform, as well as those working on the single-chip cloud (SCC).

While NVIDIA has enjoyed the advantage of actually having products in the field to talk about, Intel has managed to capture the attention of some fence-sitters with assurances of high programmability, simple recompiles, and transparent scalability for its Many Integrated Core (MIC) coprocessors. But according to NVIDIA’s Steve Scott, such promises ignore certain hard truths about how accelerator-based computing really works.

But the company’s research arm has been devising a manycore chipset, which would outrun the average-sized HPC cluster of today. The design represents a radical leap in performance, and if implemented, would fulfill the promise of exascale computing.
