  2. Shared memory - Wikipedia

    en.wikipedia.org/wiki/Shared_memory

    HSA defines a special case of memory sharing, where the MMU of the CPU and the IOMMU of the GPU have an identical pageable virtual address space.. In computer hardware, shared memory refers to a (typically large) block of random access memory (RAM) that can be accessed by several different central processing units (CPUs) in a multiprocessor computer system.

  3. Bus (computing) - Wikipedia

    en.wikipedia.org/wiki/Bus_(computing)

    Four PCI Express bus card slots (from top to second from bottom: ×4, ×16, ×1 and ×16), compared to a 32-bit conventional PCI bus card slot (very bottom). In computer architecture, a bus (historically also called a data highway [1] or databus) is a communication system that transfers data between components inside a computer or between computers. [2]

  4. Distributed shared memory - Wikipedia

    en.wikipedia.org/wiki/Distributed_shared_memory

    In computer science, distributed shared memory (DSM) is a form of memory architecture where physically separated memories can be addressed as a single shared address space. The term "shared" does not mean that there is a single centralized memory, but that the address space is shared—i.e., the same physical address on two processors refers to ...

  5. Data architecture - Wikipedia

    en.wikipedia.org/wiki/Data_architecture

    Data integration, for example, should be dependent upon data architecture standards since data integration requires data interactions between two or more data systems. A data architecture, in part, describes the data structures used by a business and its computer applications software .

  6. Storage area network - Wikipedia

    en.wikipedia.org/wiki/Storage_area_network

    The Storage Networking Industry Association (SNIA) defines a SAN as "a network whose primary purpose is the transfer of data between computer systems and storage elements". But a SAN does not just consist of a communication infrastructure, it also has a software management layer. This software organizes the servers, storage devices, and the ...

  7. Harvard architecture - Wikipedia

    en.wikipedia.org/wiki/Harvard_architecture

    Harvard architecture. The Harvard architecture is a computer architecture with separate storage [1] and signal pathways for instructions and data. It is often contrasted with the von Neumann architecture, where program instructions and data share the same memory and pathways. This architecture is often used in real-time processing or low-power ...

  8. Cache coherence - Wikipedia

    en.wikipedia.org/wiki/Cache_coherence

    In computer architecture, cache coherence is the uniformity of shared resource data that is stored in multiple local caches. In a cache coherent system, if multiple clients have a cached copy of the same region of a shared memory resource, all copies are the same.

  9. Data sharing - Wikipedia

    en.wikipedia.org/wiki/Data_sharing

    Data sharing is the practice of making data used for scholarly research available to other investigators. Many funding agencies, institutions, and publication venues have policies regarding data sharing because transparency and openness are considered by many to be part of the scientific method. [1]
