shared-memory architecture

{{Short description|Distributed computing architecture}}

A shared-memory architecture (SM) is a distributed computing architecture in which the nodes share the same memory as well as the same storage.{{Cite web |title=Memory: Shared vs Distributed - UFRC |url=https://help.rc.ufl.edu/doc/Memory:_Shared_vs_Distributed |access-date=2024-03-13 |website=help.rc.ufl.edu}}

It contrasts with shared-nothing architecture, in which each node has distinct memory and storage, and with shared-disk architecture, in which the nodes share the same storage but not the same memory.

This is distinct from the use of shared memory between different programs or threads on a single node, with or without multiprocessing.
