The definition of atomic is hazy; a value that may be atomic in a single application can be non-atomic in A different. For the common guideline, a worth is non-atomic if the appliance offers with just a Section of the value.
What helps prevent An additional core from accessing the memory deal with soon after the main has fetched it but prior to it sets the new worth? Does the memory controller deal with this?
Do not forget, this doesn't mean which the residence in general is thread-Harmless. Only the method connect with on the setter/getter is. But if you employ a setter and following that a getter at the same time with two different threads, it could be damaged too!
