In a concurrent program, memory ordering describes the guarantees an implementation gives about the visibility and relative ordering of memory accesses performed by multiple threads. Modern compilers and processors freely re-order ordinary loads and stores to improve performance, as long…
Modern processors can run at different speeds (and voltages) depending on demand. Running at higher clock frequencies makes the CPU perform more operations per second but also draws more power and generates more heat. CPU frequency scaling (often part of…
