symmetric multiprocessor การใช้

• It is based on symmetric multiprocessor hardware.
• The term " symmetric multiprocessor " is used in the majority of the technical papers.
• He also helped start Encore Computer Encore Computer, a pioneer in symmetric multiprocessors, forerunner of today's multicore processors.
• Simple symmetric multiprocessors place a number of CPUs on a shared FSB, though performance could not scale linearly due to bandwidth bottlenecks.
• DMS is additionally unusual in being implemented in a parallel programming language, PARLANSE, that uses symmetric multiprocessors available on commodity workstations.
• In 1969, company Honeywell introduced its first Multics system, a symmetric multiprocessor system capable of running up to eight processors in parallel.
• The POWER7 superscalar symmetric multiprocessor architecture was a substantial evolution from the POWER6 design, focusing more on power efficiency through multiple cores and simultaneous multithreading ( SMT ).
• "' POWER8 "'is a family of superscalar symmetric multiprocessors based on the Power Architecture, and introduced in August 2013 at the Hot Chips conference.
• Nowadays parallel shared memory symmetric multiprocessors ( SMP ) are complex machines, where a large number of architectural aspects have to be simultaneously addressed in order to achieve high performance.
• While this is not possible anymore due to the prevalence of symmetric multiprocessor and multi-core systems, the bugs in the firmware and the operating systems are now a rare occurrence.
• J2 implements instructions for dynamic shift ( using the SH-3 and later instruction patterns ), extended atomic operations ( used for threading primitives ) and locking / interfaces for symmetric multiprocessor support.
• In DragonFly, each caches in Symmetric Multiprocessor Systems do not contain duplicated data, allowing for higher performance by giving each processor in the system the ability to use its own cache to store different things to work on.
• ARM big . LITTLE is an exception where the ISAs of cores are the same and heterogeneity refers to the speed of different microarchitectures of the same ISA, then making it more like a symmetric multiprocessor system ( SMP ).
• The first 1108 computers used symmetric multiprocessor versions of the 1108 with up to 4 processors and the earlier operating systems ( really " basic monitor " programs ) weren t designed for that, even though they supported limited multiprogramming.
• The Butterfly began with a proprietary operating system called Chrysalis, but moved to a Mach kernel operating system in 1989 . While the memory access time was non-uniform, the machine had SMP memory semantics, and could be operated as a symmetric multiprocessor.
• "' Symmetric multiprocessing "'( "'SMP "') involves a symmetric multiprocessor system hardware and software architecture where two or more identical processors are connected to a single, shared main memory, have full access to all I / O devices, and are controlled by a single operating system instance that treats all processors equally, reserving none for special purposes.
• In the 70s, he developed the reservation table approach to optimum design and cyclic scheduling of pipelines, designed and implemented an eight-node symmetric multiprocessor ( SMP ) system in 1976, and developed a variety of systematic methods for modeling performance and enhancing systems, including early work on simulated annealing, wave pipelining, multiple instruction stream pipelines, decoupled access-execute architecture, and polycyclic scheduling ( aka software pipelining ).
• The first APIC was the 82489DX it was a discrete chip that functioned both as local and I / O APIC . The 82489DX enabled construction of symmetric multiprocessor ( SMP ) systems with the Intel 486 and early Pentium processors; for example, the reference two-way 486 SMP system used three 82489DX chips, two as local APICs and one as I / O APIC . Starting with the P54C processor, the local APIC functionality was integrated into the Intel processors'silicon.
