difference between SMP and non-SMP

Matched CPUs.

In SMP, volatile memory latency and control is assumed to be same for each processor to each memory module on the system leading to simpler board and system design

a popular non-SMP is NUMA ( Non Uniform Memory Access ) which allows the CPU on the same system board to have more control over the nearby memory relative to other CPUs on the other system boards of the system

- Sur> What is the difference between SMP and non-SMP systems ?

symmetrical setups allow the tasks to be distributed symmetrically, and each cpu can do the task of the other. Non-symmetrical setups usually have defied tasks for the cpus, eg one is the graphics engine and such. SMP setups can be scaled up.
