尽管断言失败了,但是CPU1还是处理了队列中的invalidate消息,并真的invalidate了包含a的cache-line,但是为时已晚 出现问题的原因是,当CPU排队某个invalidate消息后,并做错了应答Invalidate Ack, 但是在它还没有处理这个消息之前,就再次读取了位于cache中的数据,该数据此时本应该已经失效,但由于未处理invalidate消息导致使用...

如果该数据已经在A cpu的cache中,但是是read only的,这时候,该cpu不能直接操作cacheline中的对应的数据(因为是read only的),这种cache miss被叫做write miss。 一旦A cpu完成了invalidate其他cpu cache中的数据,该cpu可以不断的写或者读取其cache中的数据。 (注意:为了表述方便,我这里给指定cpu命名为A) communicat...
Cache hit Given a resource is cached When a read request comes in for the resource Then the controller fulfils the request by going to the cache Scenario: Cache invalidation Given a resource is cached When a write request on the resource is performed Then the cache invalidates the resource ...
Frob.Gnusto 10, "lords a leaping" Two objects sharing the same variable but with different types may have the same method name but different dispids. We would have to invalidate our cache every time the variable was changed, which is a lot of work to save very little time...

Modules are fetched over HTTP requests. Vite leverages HTTP headers for caching to speed up full-page reloads. Source code module requests are made conditional via 304 Not Modified. And dependency module requests are cached via Cache-Control: max-age=31536000, immutable. ...
Clearing a reference object invalidates the soft, weak, or phantom reference contained in the reference object. For example, if the program or garbage collector were to invoke clear() on the SoftReference object shown in Figure 9-4, the soft reference to the Cow object would be invalidated,...
