Speculative multi-threading (OMG "reverse hyper-threading") Intel research processor

[pxc]

This is a few months old and I didn't find a thread when I searched, so here ya go. It looks like more research to benefit future Larrabee-derived and "datacenter on a chip" processors, but seems to also have been modeled on workstation-type loads. http://www.xbitlabs.com/news/cpu/di...le_Threaded_Software_on_Multi_Core_Chips.html

The interesting parts:

According to Intel, the proposed hardware/software scheme outperforms previous hardware-only schemes to implement the idea of combining cores for executing single-thread applications in a multi-core design by more than 10% on average on Spec2006 for all configurations. Moreover, single-thread performance is improved by 41% on average when the proposed scheme is used on a so-called “tiny-core” (Intel did not reveal, what tiny-core actually is, but it may potentially be a part of the company’s SSC 48-core processor), and up to 2.6 times for some selected applications.

At the present Anaphase is a research project and the Intel Labs Barcelona researchers are looking into ways how to potentially integrate this technology into future processor designs.

It is not a product, not in any products and please don't anyone start with the brain cell killing "AMD has reverse hyper-threading too" stuff. No, it doesn't.
