Abstract
A page table entry dirty bit system may be utilized to record dirty information for a software distributed shared memory system. In some embodiments, this may improve performance without substantially increasing overhead because the dirty bit recording system is already available in certain processors. By providing extra bits, coherence can be obtained with respect to all the other uses of the existing page table entry dirty bits.
