How to Optimize Cache Line Read Access with Minimal Writer Cache Impact on x86?
I’m working with an x86 processor and need to read data that resides in another processor’s cache line. I am coding in C++. The data is initially in an Exclusive (E) or Modified (M) state in the owner’s cache, and when I read it, it transitions to a Shared (S) state. Data resides in a single cache line.
