<p class=MsoNormal style='margin-left:.5in'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>Hyper-Threading technology enables
this thread-level parallelism (TLP) by duplicating the architectural state on
each processor, while sharing one set of processor execution resources. When
scheduling threads, the operating system treats the two distinct architectural
states as separate "logical" processors. This allows multi-processor
capable software to run unmodified on twice as many logical processors. While
Hyper-Threading technology will not provide the level of performance scaling
achieved by adding a second processor, benchmark tests show some server
applications can experience 30 percent gain in performance.<o:p></o:p></span></font></p>
