  2. Shared memory - Wikipedia

    en.wikipedia.org/wiki/Shared_memory

    POSIX also provides the mmap API for mapping files into memory; a mapping can be shared, allowing the file's contents to be used as shared memory. Linux distributions based on the 2.6 kernel and later offer /dev/shm as shared memory in the form of a RAM disk , more specifically as a world-writable directory (a directory in which every user of ...

  3. SHMEM - Wikipedia

    en.wikipedia.org/wiki/SHMEM

    SHMEM (from Cray Research's “shared memory” library [1]) is a family of parallel programming libraries, providing one-sided, RDMA, parallel-processing interfaces for low-latency distributed-memory supercomputers. The SHMEM acronym was subsequently reverse engineered to mean "Symmetric Hierarchical MEMory”. [2]

  4. sbrk - Wikipedia

    en.wikipedia.org/wiki/Sbrk

    The break value can be automatically rounded up to a size appropriate for the memory management architecture. [4] sbrk and brk were considered legacy even by 1997 standards (Single UNIX Specification v2 or POSIX.1-1998). [5] They were removed in POSIX.1-2001. [6]

  5. Inter-process communication - Wikipedia

    en.wikipedia.org/wiki/Inter-process_communication

    All POSIX systems, Windows, AmigaOS 2.0+ Shared memory: Multiple processes are given access to the same block of memory, which creates a shared buffer for the processes to communicate with each other. All POSIX systems, Windows Message passing: Allows multiple programs to communicate using message queues and/or non-OS managed channels.

  6. POSIX - Wikipedia

    en.wikipedia.org/wiki/POSIX

    POSIX Conformance Testing: A test suite for POSIX accompanies the standard: VSX-PCTS or the VSX POSIX Conformance Test Suite. [ 10 ] The development of the POSIX standard takes place in the Austin Group (a joint working group among the IEEE, The Open Group , and the ISO/IEC JTC 1/SC 22 /WG 15).

  7. C POSIX library - Wikipedia

    en.wikipedia.org/wiki/C_POSIX_library

    The C POSIX library is a specification of a C standard library for POSIX systems. It was developed at the same time as the ANSI C standard. Some effort was made to make POSIX compatible with standard C ; POSIX includes additional functions to those introduced in standard C.

  8. mmap - Wikipedia

    en.wikipedia.org/wiki/Mmap

    The main difference between System V shared memory (shmem) and memory mapped I/O (mmap) is that System V shared memory is persistent: unless explicitly removed by a process, it is kept in memory and remains available until the system is shut down. mmap'd memory is not persistent between application executions (unless it is backed by a file).

  9. pthreads - Wikipedia

    en.wikipedia.org/wiki/Pthreads

    In computing, POSIX Threads, commonly known as pthreads, is an execution model that exists independently from a programming language, as well as a parallel execution model. It allows a program to control multiple different flows of work that overlap in time.
