A method and apparatus for filtering memory probe activity for writes in a distributed shared memory computer. In one embodiment, the method may include initiating a first store operation to a cache data block stored in a first cache from a first processing node; assigning a modified cache state to said cache data block in response to initiating said first store operation. The method may further include initiating a first load operation to said cache data block from a second processing node; and assigning a pairwise-shared directory state to a coherence directory entry corresponding to said cache data block in response to initiating said first load operation, where the pairwise-shared directory state is distinct from a shared directory state.
