This document discusses hyper-threading technology. It begins with an introduction and overview of hyper-threading and how it works. Specifically, it allows a single processor to act like multiple processors by enabling simultaneous multi-threading. It then discusses how hyper-threading is implemented on Intel Xeon processors and the performance improvements it provides for multimedia applications. In closing, it reiterates how hyper-threading offers more efficient use of processor resources through greater parallelism.

3.  Ground breaking technology from the intel that allows processor to work
more efficiently.
 Technology enables the processor to execute series of instruction allows at
the same time.
 Improved the onboard so that the second thread can be processed in the
same processor.
 Hyper-threading provides two logical processor in a single logical
processor.

4.  Is a technique used to improve parallelization of computations performed
on PC microprocessor.
 Is a technique which enables single CPU to act like multiple CPU’s.
 Enables different parts of the CPU to work on different tasks concurrently.
 Threaded software application to execute threads in parallel in a single
multi-core processor instead of thread processing in linear fashion.

5.  Hyper-threading technology takes advantage of multithreading capability.
 Processor use the resources otherwise would sit idle and done more work
in same amount time.
 Divide the workload into processes and threads
 Execute the threads on different processors.

16.  Intel Xeon Hyper-Threading is definitely having a positive
impact on Linux kernel and multithreaded applications.
 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.
