Hyper-Threading Technology - HP xw8400 Service And Technical Reference Manual

Hyper-Threading Technology

Hyper-Threading Technology, developed by Intel®, enables a single processor to execute multiple
threads of instructions simultaneously. Hyper-Threading Technology enables the processor to utilize its
execution resources more efficiently, delivering performance increases and improving user productivity.
Not all applications or environments benefit from the Hyper-Threading Technology. Hyper-Threading is
most beneficial in multi-tasking environments.
To see if Hyper-Threading Technology can benefit you, test your system by enabling the feature. To do
this, run Computer Setup (F10) during the boot process and select Advanced>Power-On
Option>Hyper-Threading, and enable Hyper-Threading Technology.
NOTE
technology is detected by the system and is turned on in the operating system after it is enabled
in the system BIOS.
Hyper-threading functions with Intel Xeon(TM) 5000 Series processors.
With the release of Red Hat Enterprise Linux, Hyper-Threading Technology is compatible with
Linux-based systems. Before this technology can be enabled, a Simple Management Protocol
(SMP) kernel must be installed on your system.
