When you do the math, that’s 60 cores per chip (Intel is promising more than this), with four-way hyperthreading. Although the appearance of the sled server’s heat sink can fool you, that’s just one big chip under there — the largest die that Intel has ever produced for a CPU.
As Knights Landing chief architect Avinash Sodani confirmed, all threads were being run on a single image of a single physical (non-virtual) operating system. Had this image been Windows, said Sodani, the operating system would already have been able to manage all 240 threads just as evenly, without extensions to the operating system.
This means, with Knights Landing, there won’t be a “main core” backed up by 60 or more subsidiaries which the operating system activates when it gets around to it. “It’ll look like everyone is at the same level,” he said. “There’s no master/slave kind of relationship.”
Ich wäre da nicht so sicher
...und weiter...
That said, this reporter still asked one of the engineers on-site what Intel is asked to demonstrate, when it’s showing off Knights Landing to people other than the press — say, to prospective OEMs.
They want to see ease of programmability, the 15-year veteran engineer told DatacenterDynamics, and ease of workload portability. Could their apps, compiled for a different class of processor (probably Xeon) execute with just as much ease on Xeon Phi? Some of these prospects are specifically interested in high-performance workloads, though he admitted, not everyone wants to see Xeon Phi executing HPC exclusively.
The demonstration was part of Intel’s stepped-up efforts to promote its forthcoming Knights Landing Xeon Phi as a stand-alone processor, as well as a co-processor package like the current-day Knights Corner series.

Madman1209,
eben nicht! Knights Corner verfolgt einen "network on a chip" Ansatz. Das ist nicht wie früher, wo man mit Network Nodes arbeiten musste. Es wird genau das Gegenteil sein, von dem was Du geschrieben hast. Die Karte einstecken und Windows wird mit über 72 CPU Kernen und nochmal mehr Threads arbeiten. Genial oder? Du kannst Xeon Phi sogar als *stand-alone* Prozessor verwenden.
