What Is Hyper-threading?

[deorsa]

Hyper-threading, formally named Hyper-Threading Technology(HTT), is Intel's brand due to their execution of the simultaneous multithreading technology around the Pentium 4 microarchitecture. It's a far more sophisticated type of Very-threading that debuted in U.S. patent 4,847,755(Gordon Morrison, et. al) and is visible being used around the Intel Xeon processors and was later put into Pentium 4 processors. The technology improves model performance under certain workloads by giving useful function for delivery models that will normally be idle, for instance throughout a cache miss. A Pentium 4 with Hyper-Threading enabled is handled from the operating-system as two processors in the place of one.

Hyper-Threading is just a function of particular Pentium 4 chips which makes one physical processor seem as two logical processors. It employs extra registers to overlap two instruction streams to be able to accomplish an estimated 30% gain in efficiency. Multithreaded programs make the most of the Super-Threaded equipment because they might on any dual-brand system.

A technology produced by Intel that allows multithreaded computer programs to implement threads in parallel for a passing fancy multiple-core model in the place of running posts in a linear style. Older methods took advantage of dual-running threading in software by splitting instructions into multiple channels to ensure that several model might work upon them at once.

Hyper-threading, officially called Hyper-Threading Technology(HTT), is Intel's trademark for their implementation of the simultaneous multithreading technology on the Pentium 4 microarchitecture. It is a more advanced form of Super-threading that debuted in U.S. patent 4,847,755(Gordon Morrison, et. al) and can be seen in use on the Intel Xeon processors and was later added to Pentium 4 processors. The technology improves processor performance under certain workloads by providing useful work for execution units that would otherwise be idle, for example during a cache miss. A Pentium 4 with Hyper-Threading enabled is treated by the operating system as two processors instead of one.
