The point it does mention is about locking the memory bus which I assume is simply practical for MP techniques where by there may be much more CPUs endeavoring to access similar location at similar time.
What this means is the CPU executing the atomic Directions mustn't respond to any cache coherency protocol messages for this cacheline from the suggest time. Though the devil is in the small print of how This can be executed, at-least it gives us a mental model
three @AaryamanSagar: std::atomic is a sort that allows for atomic operations. It doesn't magically make your lifetime far better, you continue to have to know what you would like to accomplish with it. It is really for an incredibly particular use situation, and makes use of of atomic functions (on the item) are generally quite delicate and should be considered from a non-neighborhood standpoint.
To access that cache line the opposite Main has to get obtain rights initially, and the protocol to get those rights involves the current operator. In effect, the cache coherency protocol prevents other cores from accessing the cache line silently.

Multithreading means: various threads can examine a shared piece of information concurrently and we is not going to crash, however it doesn't warranty that you aren't studying from the non-autoreleased worth. With thread protection, It can be assured that what you examine just isn't auto-released.
