Caches in Clovertown are inclusive or exclusive?

Caches in Clovertown are inclusive or exclusive?

Ritratto di Hamid Reza K.

Hello,

I am researching on multi-core scheduling algorithms, and need some information about Intel Xeon 5310 (Clovertown) processor. As you know, Clovertown is a two-package quad-core processor. Each package consists of a dual core processor. So, Could you tell me caches are inclusion or exclusion in Clovertwon?
I asked the question from Intel support centre, and found that all caches are inclusive. So, I have another question. Suppose block x is loaded to L1 cache of core0 in Clovertown (block x will be loaded to shared L2 cache). Then, the block is evicted from L1 of core0. (Therefore, block x will be evicted form shared L2). After a while, core1 accesses to block x. In this case, L2 cannot help core1 to retrieve block x. In the other words, inclusion has negative effect on thread affinity. Isn't it true?

 

Thanks
