For a while now there have been rumors surfacing around the Internet of Advanced Micro Devices (AMD) developing a reverse Hyper-Threading technology. This technology would basically be an inverse of Intel's Hyper-Threading to make two cores function as one. It was believed by some that the technology was already embedded into the Athlon 64 X2 AM2 processors, and that shortly after Intel releases Conroe, AMD would come to the table with a miracle BIOS update and driver to implement this function. The purpose of reverse Hyper-Threading would be to improve the performance in single-threaded environments.
What has yet to be cleared from Phoronix sources is the position of Reverse HT on Linux, and if there would be such support. On top of an updated motherboard BIOS, it is expected that a new driver will be needed. Microsoft has been reportedly developing a Windows patch/update so the two physical AMD cores are properly recognized as a single core. Though, with much in Linux already supporting SMP, it's unclear as to the extent of the benefits in most environments, and if the support would even be available. Though, if any unprotected words come along about Reverse HT + Linux, it will be passed along.
Contrary to the reports of AM2 Reverse HT coming along shortly after the Conroe launch, a very reliable source has reported to us that this technology won't actually appear until becoming a feature with the K10/K8L Greyhound generation...
Just some food for thought, and of course, Advanced Micro Devices has not officially commented on these matters.
Feel free to discuss Reverse Hyper-Threading/Anti Hyper-Threading.
