The memory controller is just accountable for ensuring that memory & cache on distinct processors stays steady - in case you publish to memory on CPU1, CPU2 is not going to have the capacity to examine something else from its cache.

To the OP: Certainly this implementation enables concurrent usage of the elements from the vector, but not the vector itself. If, say, a person thread modifies the worth saved in among the atomics while A further thread provides new components to the vector, a vector reallocation may perhaps arise and the thing the initial thread modifies could possibly be copied from a person area from the vector to another.
I am meaning to declare a vector of atomic variables for use as counters in a multithreaded programme. Here's what I attempted:
Cache coherency protocol by by itself just isn't enough to put into practice atomic operations. Let's imagine you want to put into action an atomic increment. Down below will be the actions included
A simplified look into the composition of the atomExplore an atom's interior to find out the format of its nucleus, protons, and electrons.
But for UP (And perhaps MP), If a timer interrupt (or IPI for SMP) fires With this smaller window of LDREX and STREX, Exception handler executes maybe variations cpu context and returns to The brand new undertaking, on the other hand the surprising element comes in now, it executes 'CLREX' and therefore removing any special lock held by past thread. So how greater is employing LDREX and STREX than LDR and STR for atomicity on the UP method ?

The main element is they allow concurrent accessibility and modification safely and atomicwallet securely.
