Problem Statement
What does NUMA (Non-Uniform Memory Access) architecture imply in a multi-processor system?
Explanation
In a NUMA architecture each processor has local memory which it can access more quickly; accessing another processor’s memory or a shared region may incur higher latency. Modern OS kernels must be NUMA-aware when scheduling tasks or managing memory to optimise performance on large servers. Recognising this shows advanced OS knowledge. :contentReference[oaicite:1]{index=1}
