Dear Tyler thanks a lot for your reply.
In the second case (it's a data from a page that gets mapped into all
processes or something, in which case it's shared as expected) all the
processes will use the same virtual address to access the memory?

The caches should be physically tagged (though virtually indexed).
The use of a physical tag guarantees that even if you index with a a
virtual address from another process's address space space, you will
likely see a physical tag mismatch (unless it's a data from a page that
gets mapped into all processes or something, in which case it's shared as
expected).

Dear all,
in the case of single core ooo model, how does the simulator ensure that
different processes will not access the same cache line of in a Cache?
In my knowledge, I would expect an invalidation of cache hierarchy
whenever the executed process is changed or a way of process-id marking
of each cache line.
What do you think about?
