Non-Uniform Memory Access (NUMA)
Definition
In NUMA, memory access depends on the assignment to the processor.
A multiprocessor memory architecture where access time and bandwidth depend on which processor the memory is physically assigned to.
Simply explained
A computing unit reaches its closer memory at a different speed than memory at another computing unit.
Why it matters in practice
Helps develop and operate digital systems robustly, securely, and maintainably.
Example from business
An inference process binds threads and memory to the same NUMA node.
Limits and pitfalls
- Consider total memory as equally fast or ignore thread and memory placement.
Origin & history
NUMA was developed for scalable multiprocessor systems and is relevant in many servers today.
Use in mid-sized companies
- Possible application: An inference process binds threads and memory to the same NUMA node.
