HT Seminar Filmawit

The document discusses Hyper-Threading Technology which allows a single physical processor to appear and function as multiple logical processors. It was first introduced in 2002 and brings simultaneous multi-threading to Intel Architecture by making a single processor appear as two logical processors and sharing execution resources. The advantages include improved overall system performance, throughput, and reaction times while the disadvantages include higher power consumption and potential shared resource conflicts.

First appeared in February 2002 on Xeon server processors and in November 2002
on Pentium 4 desktop CPUs.
Brings the concept of simultaneous multi-threading to the Intel Architecture.

Makes a single physical processor appear as two logical processors.

Is a form of simultaneous multithreading technology (SMT), where multiple


threads of software applications can be run simultaneously on one processor.

First used in Intel Xeon MP processor.

Makes a single physical processor appear as multiple logical processors.

Each logical processor has a copy of architecture state.

Logical processors share a single set of physical execution resources.

No performance loss if only one thread is active. Increased


performance with multiple threads.
Improved overall system performance
Improved throughput, because tasks run on separate threads
Improved reaction and response time

Improve productivity by doing more simultaneously without slowing


down
Provide faster response times for Internet and e-commerce
applications
Increase the number of transactions that can be processed
simultaneously
Improved reaction and response times for end-users and customers.

Higher Power Consumption

Shared resource conflicts

Intel Xeon Hyper-Threading is definitely having a


positive impact on Linux kernel and multithreaded
applications. Hyper Threading Technology will
become increasingly important going forward as it
adds a new technique for obtaining additional
performance for lower transistor and power costs.
