Why is the NUMA design more scalable than the UMA design?
a) NUMA systems are loosely coupled, whereas UMA systems are tightly coupled.
b) NUMA systems reduce bus collisions when each processor's local memory services most of the processor's memory requests. By contrast, UMA systems can saturate the shared bus quickly.
c) NUMA systems use more than one memory module, whereas UMA systems use only one.
d) Memory access time is faster in NUMA systems than in UMA systems.
b) NUMA systems reduce bus collisions when each processor's local memory services most of the processor's memory requests. By contrast, UMA systems can saturate the shared bus quickly.
