Hyper-threading
This HP workstation supports Hyper-threading.
Hyper-Threading Technology (HTT), is an Intel-proprietary technology used to provide process
parallelization. The operating system treats a processor with Hyper-Threading enabled as two
processors instead of one. This improves performance under certain workloads by getting useful work
from parts of the processor that would otherwise remain idle. Hyper-threading relies on support from
the operating system as well as the CPU.
To implement hyper-threading, see
The Computer Setup (F10) Utility on page 31.
