    A reasonable model is sequential consistency (SC), which makes a shared memory multiprocessor behave like a multiprogrammed uniprocessor. Since SC appears to limit some of the optimizations useful for aggressive hardware implementations, researchers and practitioners have defined several relaxed consistency models.Author: Mark Hill

    This paper argues that multiprocessors should implement SC or, in some cases, a model that just relaxes the ordering from writes to reads. I argue against using aggressively relaxed models because, with the advent of speculative execution, these models do not give a sufficient performance boost to justify exposing their complexity to the authors of low-level software.

    The hardware should provide a well-defined interface for shared memory and it should provide a high-performance implementation of the interface. UNIPROCESSOR MEMORY Defining a shared memory multiprocessor’s interface to memory is easier if we first consider how memory is defined in a uniprocessor. A uniprocessor executes instructions and memory operations in a dynamic execution …

    A multiprocessor can use the same relatively-simple memory interface as a multiprogrammed uniprocessor. This memory consistency model was formalized by Lam-port assequential consistency (SC) [8]. Section2 argues the benefits of SC. Perhaps surprisingly, the hardware memory consistency models of most commercial multiprocessors are not SC.

Multiprocessing - Wikipedia

    https://en.wikipedia.org/wiki/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.

    Fortunately, once it is identified, false sharing can be easily eliminated by setting the memory layout of non-shared data. Apart from eliminating bottlenecks in the system, a multiprocessor operating system developer should provide support for efficiently running user applications on the multiprocessor.
