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...
假设初始时a和b的值都是0,a处于CPU1-cache中,b处于CPU0-cache中。如果按照下面流程执行这段代码: CPU 0 starts executing the a = 1 CPU 0 looks “a” up in the cache, and finds that it is missing CPU 0 therefore sends a “read invalidate” message in order to get exclusive ownership of...

Caches often lack high availability properties and can easily fail or invalidate records depending on their heuristics. Partial failures, which are more common, are even worse in terms of consistency. When the cache inevitably fails, the database will get hit by the unmitigated firehose of queries...

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,...

这个系统被称为non-uniform cache architecture (NUCA) 的系统,为了公平的分配Interconnect到各个CPU之间的带宽,我们在Node和interconnect器件之间的接口设计了per cpu的Message queue。尽管,一个指定CPU的内存访问可以通过memory barrier对访问顺序进行约定,但是,一对CPU上的内存访问可以被完全打乱重排,下面我们会详细描述。
Using of Individual Taxpayer Identification Number in place of a worker's SSN invalidates the data. With that, verify their SSNs using the Social Security Number Verification Service. You can also run the Employee Details report to check the full details. To do th...
they serve a file from the edge until a new build invalidates the file. Netlify/Zeit/Firebase etc. work this way. Most/all CDNs have a purge or invalidation API that can be setup to do this as well. What CDNs are y'all using? Let's put together some docs on setups. This does...
