606 CACHE COHERENCE AND THE COHERENCE ORDER RELATION: co, coi, and coe
609 Cache coherence is a general principle requiring that in a
613 ordering which all the CPUs agree on (the coherence order), and this
617 To put it another way, for any variable x, the coherence order (co) of

624 You can think of the coherence order as being the order in which the
628 coherence order, that is, if the value stored by W gets overwritten,
631 Coherence order is required to be consistent with program order. This
