Ars Technica on Hyperthreading

Posted by ryuzaki0 on from the multithreading-and-superthreading-too dept.

radiokills writes "Ars Technica has a highly-informative technical paper up on Hyper-Threading. It's a technical overview of how simultaneous multithreading works, and what problems it will introduce. It also explains why comparing the technology to SMP is Apples to Oranges, in a sense. Starting with the 3 GHz Pentium 4, this tech will be standard in Intel's desktop lines (it's already in the Xeon), so this is important stuff."

    Hyperthreading needs to be used carefully. Certain applications you will end up with signifigant performance decreases with it enabled. Hyperthreading adds additional overhead to threading models and schedulers.
