DPC supports NUMA Affinity with computing applications, maximizing multi-NUMA performance by OceanStor Pacific series.

Question

Options

• ATRUE
• BFALSE

• A
  72% (31)
• B
  28% (12)

Explanation

Option A is correct because DPC (Data Processing Controller) in the OceanStor Pacific series is designed with NUMA (Non-Uniform Memory Access) affinity support, meaning it schedules data processing tasks on CPU cores that are physically closest to the relevant memory nodes, reducing cross-node memory access latency and improving overall throughput in multi-NUMA environments. This architecture is a deliberate design feature of OceanStor Pacific to maximize performance for compute-intensive workloads. Option B is incorrect because it directly contradicts the documented capability - DPC does support NUMA affinity and this is a key performance advantage of the OceanStor Pacific platform.

Memory tip: NUMA affinity is about keeping work local - match the task to the nearest memory. Remember that DPC in OceanStor Pacific is NUMA-aware, so it does the same thing: it keeps processing close to data for maximum speed, making TRUE the only logical answer.
