NUMA — Non-Uniform Memory Access
Describes systems where memory-access cost varies by processor locality.
Why learn NUMA — Non-Uniform Memory Access?
Describes systems where memory-access cost varies by processor locality.
Where it came from
Workload placement and memory allocation can affect performance.
- Memory aid (a learning cue, not the expansion): Not all memory is Uniformly Near the processor as a cue.
