Hi Saifi, That cleared some of my doubts.Thanks a lot.
These are my findings on SMP. Each Processor uses a cache which access the same Shared Memory.They keep updating their cache with the changes that affect the Memory by "snooping". When it is a Dual Core Processor, it has two cache for the SMP kernel.On the same processor if I select the other Kernel how these are accessed.
