Hyper-Threading Technology (HTT) enables multi-threaded server applications to execute threads in parallel within each processor. HTT is a form of simultaneous multi-threading that allows multiple software threads to run simultaneously on one processor by duplicating the processor's architectural state while sharing execution resources. It provides thread-level parallelism to improve processor efficiency and performance on multi-threaded software. For HTT to work requires a compatible Intel processor, chipset, BIOS, and operating system along with multi-threaded software. HTT delivers increased system performance and responsiveness.

- 1. Seminar on Hyper-Threading Technology (HTT) Presented by: ________________ __________________ ________________________
- 2. What is HTT? Hyper-Threading technology is a groundbreaking innovation from Intel that enables multi-threaded server software applications to execute threads in parallel within each processor in a server platform.
- 3. 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.
- 4. HyperThreading Technology (HTT) is Intel's trademark for their implementation of the simultaneous multithreading technology (SMT) on the Pentium 4 micro architecture.
- 5. It is basically a more advanced form of SuperThreading that first debuted on the Intel Xeon processors and was later added to Pentium 4 processors. In SuperThreading, the processor can execute instructions from a different thread each cycle.
- 6. The Intel® Xeon™ processor family uses Hyper-Threading technology, along with the Intel® NetBurst™ microarchitecture, to increase compute power and throughput for today's Internet, e-Business, and enterprise server applications.
- 7. This level of threading technology has never been seen before in a general-purpose microprocessor. A Pentium 4 with Hyper-Threading enabled is treated by the operating system as two processors instead of one.
- 8. Overview : 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.
- 9. The architectural state tracks the flow of a program or thread, and the execution resources are the units on the processor that do the work: add, multiply, load, etc.
- 10. Why HTT??? Enterprise, e-Business, and gaming 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.
- 11. Hyper-Threading Technology (HT Technology) provides thread-level parallelism on each processor, resulting in more efficient use of processor resources, higher processing throughput, and improved performance on today's multithreaded software.
- 12. Requirements: For implementation of this technology,we need: a computer system with an Intel® processor supporting HT Technology a computer system with an Intel® processor supporting HT Technology An HT Technology enabled chipset An BIOS that supports HTT An operating system that includes optimisations for HTT
- 13. With all these enabled,it delivers increased system performance and responsiveness. The HyperThreading technology improves processor performance under certain workloads by providing useful work for execution units that would otherwise be idle, for example during a cache miss.
- 14. Performance: improved support for multi-threaded code allowing multiple threads to run simultaneously improved reaction and response time increased number of users a server can support helps increase transaction rates reduces end-user response times enhances business productivity providing a competitive edge to e-Businesses and the enterprise
- 15. Limitation Performance will vary depending on the specific hardware and software you use.
