| | Hyper-threading - Wikipedia, the free encyclopedia |
 | | This problem can be avoided by improving the scheduler to treat logical processors differently from physical processors; in a sense, this is a limited form of the scheduler changes that are required for NUMA systems. | | | The 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. | | | In May 2005 Colin Percival presented a paper, Cache Missing for Fun and Profit, demonstrating that a malicious thread operating with limited privileges in theory permits monitoring of the execution of another thread, allowing for the possibility of theft of cryptographic keys. |

| | Intel Hyper-Threading Technology Review |
| | Threads can relate to one or different applications, but there are almost always more than 1 active threads (to make sure open in the Windows 2000/XP the Task Manager and display the number of threads). | | | In this case threads are executed on one processor simultaneously, without switching between them. | | | And the threads draw a generated image in the window in turn making their contexts current alternately. |

| | Hyper-Threading Technology |
| | Threading is the process of splitting instructions into "multiple streams" within a software application. | | | With multi-threaded, MP-aware applications, instructions from several threads are simultaneously dispatched for execution by the processors. | | | The same division of workload can be found in many high-performance applications such as database engines, scientific computation programs, engineering-workstation tools, and multi-media programs. |

| | If one thread is reading data from an instance of OClass by referring to Field1, and another thread on the same CPU is writing to nearby memory by assigning to Field2, it is possible (if Field1 and Field2 are close enough) that Field1 and Field2 will share a cache line. | | | If the threads in your application access large chunks of memory and perform little additional work (such as copying large blocks of memory or summing up the values in an array of integers) running multiple threads on the same physical CPU might not improve performance, and can even hurt performance. | | | Since CPU cache entries are not tagged to one logical CPU, it is possible for a thread running on logical CPU 1 to access enough memory to kick the data needed for a second thread running on logical CPU 2 off the cache. |

| | Hyper Threading In-Depth |
| | The main point of the Hyper Threading technology is that during implementation of one thread of a program idle execution units can work with another thread of the program (or a thread of another program). | | | Besides, there are some interesting consequences of the Hyper Threading: changing of the programming paradigm, popularization of multiprocessing, improvement of processor performance. | | | For example, because the L2 cache is not extendable, and when active threads will try to load the cache it's possible that the struggle for the cache will result in constant clearing and reload of data in the L2 cache. |

| | A form of simultaneous multi-threading technology (SMT), Hyper-Threading technology allows multiple threads of software applications to be run simultaneously on one processor by duplicating the architectural state on each processor while the same processor execution resources is shared. | | | Hyper-Threading technology is an innovative design from Intel that enables multi-threaded software applications to process threads in parallel within each processor resulting in increased utilization of processor execution resources. | | | The first logical processor can track one software thread, while the second logical processor tracks another software thread simultaneously. |

| | These threads of information, when processed by a single conventional CPU, can only be processed one at a time in, excuse the term, “single file” fashion. | | | Both approaches result in the data being processed in separate manners and yielding the same results, because the data is fed to the processor a thread at a time. | | | In the case of Hyper-Threading, multiple threads are able to execute simultaneously without switching, which makes much better use of the resources by carrying out all processes on a single CPU. |

| | When scheduling threads, the operating system treats the two distinct architectural states as separate "logical" processors, which allows multiprocessor capable software to run unmodified on twice as many logical processors. | | | Multithreaded software divides its workloads into processes and threads that can be independently scheduled and dispatched. | | | In high-performance workstations, Hyper-Threading Technology enables thread-level parallelism (TLP) by duplicating the architectural state on each processor while sharing one set of processor execution resources. |

| | Currently Hyper-Threading enables the processor to process up to two threads at once, but in the future it may be possible for Intel to up the ante, and allow the processor to process more than two threads at once. | | | The Intel Pentium4 has a 20 stage pipeline so a mis-prediction made by the CPU will result in a harsh performance loss, while with a simultaneous multi-threading setup, one thread will persist in the pipeline; increasing performance and response time. | | | The processor also keeps track of the data processing status of each set of instructions. |
