5 unusual facts about threading


Pentium 4

Later versions featured Hyper-Threading Technology (HTT), a feature to make one physical CPU work as two logical CPUs.

Pentium D

Intel first launched Smithfield on April 16, 2005 in the form of the 3.2 GHz Hyper-threading enabled Pentium Extreme Edition 840.

The processor was based on the dual-core Pentium D branded Smithfield, but with Hyper-threading enabled, thus any operating system saw four logical processors (two physical and two virtual).

Xeon

At most two Foster processors could be accommodated in a symmetric multiprocessing (SMP) system built with a mainstream chipset, so a second version (Foster MP) was introduced with a 1 MB L3 cache and the Jackson Hyper-Threading capacity.

Hyper-threading (2× per core, starting from 5518), that was already present in pre-Core Duo processors.


Jikes RVM

2009, Jikes RVM 3.1 released under the Eclipse Public License (EPL) with significant improvements over the performance of version 3.0.1 and a switch to native threading.

Structural alignment

The optimal "threading" of a protein sequence onto a known structure and the production of an optimal multiple sequence alignment have been shown to be NP-complete.

WinRAR

Since version 3.60 (August 2006), WinRAR includes a multithreaded version of the compression algorithm, which improves compression speed on systems with multiple, dual-core, or Hyper-threading-enabled CPUs.
