Hi, This question is raised Quick Quiz 9.23 and I think it is impossible because any changes on a data structure will inevitably inflict cache miss (on other CPUs). The only way we can help is to make the reader *ignore* the cache miss, or do the invalidation proactively. I cannot think of any existing algorithm. Can anyone provide any references (if that really exist)?
