Shared-memory architecture
In computer architecture, shared memory architecture (SMA) refers to a design where multiple processors access shared memory.[1]
Shared memory architectures may use:[1]
- Uniform Memory Access (UMA): all the processors share the physical memory uniformly.
- Non-Uniform Memory Access (NUMA): memory access time depends on the memory location relative to a processor.
- Cache-only memory architecture (COMA): the local memories for the processors at a node is used as cache.
