Funny that they are using the term "neo-heterogeneous" or "new" method for heterogeneous computing. Not that "old" method.
They used Sandy Bridge and PHI to take the top.
"System uses a neo-heterogeneous architecture including 32000 of upcoming Intel Xeon processor E5-2600 V2 processors and 48000 Intel Xeon Phi coprocessors built into an innovative new architecture with a proprietary high speed interconnect known as TH Express-2."
"Sandy Bridge"?????? EXCUUUUUUUUUUUUUUUSE ME! They threw me by their numbering. The Xeon used in getting these numbers is an UNANNOUNCED version of an Ivy Bridge with 12 (TWELVE) cores.
From the Aregister.
The chip that Intel didn't want you to know about
On the x86 portion of the Tianhe-2 system, NUDT has opted for a top-bin Ivy Bridge-EP part, and Dongarra says it is, in fact, a twelve-core Xeon E5 v2 chip (specifically, the E5-2692) running at 2.2GHz. Intel is sure to be annoyed by the release of this information, since it has not announced the core count of these processors. There has been some yammering about a ten-core part up until now, but now we know there is a twelve-core part. Intel is not expected to announce these Xeon E5 v2 processors until the fall, most likely at Intel Developer Forum in September.
But as was the case with the eight-core "Sandy Bridge-EP" Xeon E5 v1 chips, Intel has ramped up production ahead of the formal launch and cherry-picked some big HPC customers to show off the processor.
