Hyper-threading. Hyper-threading (officially called Hyper-Threading Technology or HT Technology and abbreviated as HTT or HT) is Intel 's proprietary simultaneous multithreading (SMT) implementation used to improve parallelization of computations (doing multiple tasks at once) performed on x86 microprocessors.
Simultaneous multithreading (SMT) is one of the two main implementations of multithreading, the other form being temporal multithreading (also known as super-threading). In temporal multithreading, only one thread of instructions can execute in any given pipeline stage at a time. In simultaneous multithreading, instructions from more than one ...
Multithreading (computer architecture) For threads in software, see Thread (computing). A process with two threads of execution, running on a single processor. In computer architecture, multithreading is the ability of a central processing unit (CPU) (or a single core in a multi-core processor) to provide multiple threads of execution.
For example, a four-port, 1000 ... Hyper-Threading is officially known as Hyper-Threading Technology (HTT) or HT Technology. Because of this potential for confusion ...
Simultaneous multithreading (of which Intel's Hyper-Threading is the best known) was an early form of pseudo-multi-coreism. A processor capable of concurrent multithreading includes multiple execution units in the same processing unit—that is it has a superscalar architecture—and can issue multiple instructions per clock cycle from multiple ...

Multiprocessing. Multiprocessing is the use of two or more central processing units (CPUs) within a single computer system. [1][2] The term also refers to the ability of a system to support more than one processor or the ability to allocate tasks between them. There are many variations on this basic theme, and the definition of multiprocessing ...
For example, a system with two dual-core hyper-threaded CPUs presents a challenge to a scheduling algorithm. There is complete affinity between two virtual CPUs implemented on the same core via hyper-threading, partial affinity between two cores on the same physical processor (as the cores share some, but not all, cache), and no affinity ...
