Multithreading (computer architecture) 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 .
Diagram of a symmetric multiprocessing system. Symmetric multiprocessing or shared-memory multiprocessing (SMP) involves a multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single, shared main memory, have full access to all input and output devices, and are controlled by a single operating system instance that treats all ...
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 ...
Multiprocessor system with a shared memory closely connected to the processors. A symmetric multiprocessing system is a system with centralized shared memory called main memory (MM) operating under a single operating system with two or more homogeneous processors. There are two types of systems: Uniform memory-access (UMA) system; NUMA system
Granularity (parallel computing) In parallel computing, granularity (or grain size) of a task is a measure of the amount of work (or computation) which is performed by that task. [1] Another definition of granularity takes into account the communication overhead between multiple processors or processing elements.
A multi-core processor ( MCP) is a microprocessor on a single integrated circuit (IC) with two or more separate central processing units (CPUs), called cores to emphasize their multiplicity (for example, dual-core or quad-core ). Each core reads and executes program instructions, [ 1] specifically ordinary CPU instructions (such as add, move ...
Thread (computing) In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system. [ 1] In many cases, a thread is a component of a process. The multiple threads of a given process may be executed concurrently (via ...
The minimum that is required to take advantage of hyper-threading is symmetric multiprocessing (SMP) support in the operating system, since the logical processors appear no different to the operating system than physical processors. It is possible to optimize operating system behavior on multi-processor, hyper-threading capable systems.
