What does "atomic" mean in programming? - Stack Overflow
"An operation acting on shared memory is atomic if it completes in a single step relative to other threads. When an atomic store is performed on a shared memory, no other thread can observe the modification half-complete. When an atomic load is performed on a shared variable, it reads the entire value as it appeared at a single moment in time."

What are atomic operations for newbies? - Stack Overflow
Here, each upsert is atomic: the first one left count at 2, the second one left it at 3. Everything works. Note that "atomic" is contextual: in this case, the upsert operation only needs to be atomic with respect to operations on the answers table in the database; the computer can be free to do other things as long as they don't affect (or are ...

c++ - What exactly is std::atomic? - Stack Overflow
std::atomic<> wraps operations that, in pre-C++ 11 times, had to be performed using (for example) interlocked functions with MSVC or atomic bultins in case of GCC. Also, std::atomic<> gives you more control by allowing various memory orders that specify synchronization and ordering constraints. If you want to read more about C++ 11 atomics and ...

What are atomic types in the C language? - Stack Overflow
The type sig_atomic_t is always an integer data type, but which one it is, and how many bits it contains, may vary from machine to machine. Data Type: sig_atomic_t This is an integer data type. Objects of this type are always accessed atomically. In practice, you can assume that int is atomic. You can also assume that pointer types are atomic ...

atomic operations and atomic transactions - Stack Overflow
Atomic Operations on the other hand are usually associated with low-level programming with regards to multi-processing or multi-threading applications and are similar to Critical Sections. For example, if two threads both access and modify the same variable, each thread goes through the following steps:

What's the difference between the atomic and nonatomic attributes?
Atomicity property attributes (atomic and nonatomic) are not reflected in the corresponding Swift property declaration, but the atomicity guarantees of the Objective-C implementation still hold when the imported property is accessed from Swift. So — if you define an atomic property in Objective-C it will remain atomic when used by Swift.

sql - What is atomicity in dbms - Stack Overflow
The definition of atomic is hazy; a value that is atomic in one application could be non-atomic in another. For a general guideline, a value is non-atomic if the application deals with only a part of the value. Eg: The current Wikipedia article on First NF (Normal Form) section Atomicity actually quotes from the introductory parts above.

What is the difference between atomic and critical in OpenMP?
Atomic Operations. If, as in the example above, our critical section is a single assignment, OpenMP provides a potentially more efficient way of protecting this. OpenMP provides an atomic directive which, like critical, specifies the next statement must be done by one thread at a time: #pragma omp atomic global_data++; Unlike a critical directive:

How are atomic operations implemented at a hardware level?
The atomic instructions involve utilizing a lock prefix on the instruction and having the destination operand assigned to a memory address. The following instructions can run atomically with a lock prefix on current Intel processors: ADD, ADC, AND, BTC, BTR, BTS, CMPXCHG, CMPXCH8B, DEC, INC, NEG, NOT, OR, SBB, SUB, XOR, XADD, and XCHG.

How to initialize a static std::atomic data member
Or for static storage like in the question, even just std::atomic data; works; static storage is zero-initialized by default, and this is sufficient for std::atomic or C _Atomic to work correctly (C17 required that and deprecated ATOMIC_VAR_INIT). –
