Hyper-Threading Technology in HP ProLiant G6 servers
Intel

four-core processors based on the Intel Microarchitecture (Nehalem) re-introduce support for Hyper-Threading (HT)
Technology, also known as simultaneous multi-threading. Each core has its own physical resources (architectural state, cache,
registers, and execution units), enabling it to appear as two logical processors to the operating system (OS). HT Technology
allows the OS to schedule two instruction streams (threads) to each core to share its physical resources (see Figure 1). For
example, the OS scheduler in Windows 2008 R2 prefers to send a software thread to an idle physical core to avoid using two
logical processors on a single core. First, the OS scheduler checks to see if an idle core is available. If an idle core is available,
the scheduler assigns a new thread to that core. If an idle core is not available, the scheduler assigns the thread to a core’s
logical processor. However, if an idle physical core becomes available after the operation starts, to increase processor
performance, the OS scheduler uses time-slicing to migrate the thread to the idle core.
Figure 1. HT Technology allows the OS to schedule two threads to each core to share the core’s physical resources.
Some workloads, such as Internet and e-c
ommerce applications and multi-tasking, may receive significant (20% to 30%)
performance gains from HT Technology. Performance gains vary based on the hardware and software used. Alternatively,
applications that routinely use high percentages of processor resources, such as high performance computing (HPC), may not
receive a measurable performance increase from HT Technology. HPC applications make better use of processor resources by
minimizing memory latencies through cache optimizations. So, although the OS may present two threads to a core as if there
are two logical processors, both threads will not have access to all of the core’s resources, resulting in a minor performance
gain. If thread contention for the core’s resources is high, processor performance may actually decrease. Intel

Turbo Boost
Technology complements HT Technology by increasing the performance of multi-threaded workloads. Turbo Boost Technology
increases the clock frequency of all active cores when some cores are idle or the processor is operating below power and
thermal design points set by the user.
Disabling HT Technology
Test applications thoroughly, or contact the software manufacturer, to determine whether HT Technology can provide a
measurable performance gain. If using HT Technology degrades application performance, it may be beneficial to disable it
through the ROM Based Setup Utility (RBSU).
