Failure in invalidating cache
The actual performance advantage is a function of a number of factors, including the degree to which parts of a multithreaded-program and/or multiple distinct programs can be executed in parallel and the architecture of the particular multiprocessor computer at hand.Multiprocessor computers may be classified by how they share information among the processors.Multiprocessor computers by definition contain multiple processors that can execute multiple parts of a computer program or multiple distinct programs simultaneously, in a manner known a s parallel computing.In general, multiprocessor computers execute multithreaded-programs or single-threaded programs faster than conventional single processor computers, such as personal computers (PCs), that must execute programs sequentially.
A cache coordinator, wherein the cache coordinator invalidates one or more cache entries in response to a signal.Use the right tools and code flux won't ever bother you.- Exposed APIs: I don't think the OP was talking about public APIs, which are admittedly much harder to change after the fact. It's definitely true that one of the largest problems facing computer science today is how to parallelize across cores/systems/networks.There is plenty of code that is still easy to refactor underneath. - Existing installations: Barring API changes, what changes internally would affect your customers? This problem may only be particularly hard because we're still used to thinking in terms of discrete processors each doing discrete tasks in sequence.This next succeeding and other succeeding nodes then repeat the steps of invalidating the cache line and forwarding the invalidate request until the node that is the tail of the list is reached.The tail node responds by sending an invalidate response to the node at the head of the sharing list.
