Hyper-Threading
Technology enables multi-threaded software applications
to execute threads in parallel. This level of
threading technology has never been seen before
in a general-purpose microprocessor. Internet,
e-Business, and enterprise software applications
continue to put higher demands on processors.
To improve performance in the past, threading
was enabled in the software by splitting instructions
into multiple streams so that multiple processors
could act upon them. Today with Hyper-Threading
Technology, processor-level threading can be utilized
which offers more efficient use of processor resources
for greater parallelism and improved performance
on today's multi-threaded software. Hyper-Threading
Technology provides thread-level-parallelism (TLP)
on each processor resulting in increased utilization
of processor execution resources. As a result,
resource utilization yields higher processing
throughput. Hyper-Threading Technology is a form
of simultaneous multi-threading technology (SMT)
where multiple threads of software applications
can be run simultaneously on one processor. This
is achieved by duplicating the architectural state
on each processor, while sharing one set of processor
execution resources. Hyper-Threading Technology
also delivers faster response times for multi-tasking
workload environments. By allowing the processor
to use on-die resources that would otherwise have
been idle, Hyper-Threading Technology provides
a performance boost on multi-threading and multi-tasking
operations for the Intel NetBurst® microarchitecture.
This technology is largely invisible to the platform.
In fact, many applications are already multi-threaded
and will automatically benefit from this technology.
However, multi-threaded applications take full
advantage of the increased performance that Hyper-Threading
Technology has to offer, allowing users will see
immediate performance gains when multitasking.
Today's multi-processing aware software is also
compatible with Hyper-Threading Technology enabled
platforms, but further performance gains can be
realized by specifically tuning software for Hyper-Threading
Technology. This technology complements traditional
multi-processing by providing additional headroom
for future software optimizations and business
growth.
Hyper-Threading
Technology offers many benefits to e-Business
and the enterprise such as:
- Enables
more user support improving business productivity
- Provides
faster response times for Internet and e-Business
applications enhancing customer experience
- Increases
number of transactions that can be processed
- Allows
compatibility with existing IA-32 applications
and operating systems
- Handles
larger workloads
- Offers
headroom for future business growth and new
solution capabilities
