Shared-memory architecture
open-in-new
<p>A shared-memory architecture (SM) is a <a href="/facts/Distributed_computing/o5nyhqTF">distributed computing</a> <a href="/facts/Software_architecture/1Hokp0Ed">architecture</a> in which the nodes share the same memory as well as the same storage. </p><p>It contrasts with <a href="/facts/Shared-nothing_architecture/EXvXTQ6E">shared-nothing architecture</a>, in which each node has distinct memory and storage, and with <a href="/facts/Shared-disk_architecture/bAv6nVEm">shared-disk architecture</a>, in which the nodes share the same storage but not the same memory. </p><p>This is distinct from the use of <a href="/facts/Shared_memory/zmpH7WuV">shared memory</a> between different programs or threads on a single node, with or without <a href="/facts/Multiprocessing/aDCfehDQ">multiprocessing</a>. </p>
