hi,
I have a quard-core intel CPU with 12M L2 cache. It says that 2 of the 4 cores are sharing the same L2 cache. So, how can I know which 2 cores are sharing a same L2 cache? Does it support remote fetch tech.? If core0 and core1 share the same L2 cache, and core2 and core3 shar the other L2 cache, when I write some data in the first L2 cache, then read the same data from core3,how the core3 can get the exact data written by core1, how does the core3 know the cache line in the 2nd L2 is invalid? does core3 read the data from core1's cache or from memory?
thanks.
