X-bit Labs has written an article about Anaphase, a new research project from Intel that aims to boost the performance of single-threaded applications by using special techniques to process them on multiple cores. You can read it over here.
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.
