In computer science, compare-and-swap (CAS) is an atomic instruction used in multithreading to achieve synchronization. It compares the contents of a memory...

contrast, compare-and-swap (32-bit comparand) offers a more general solution to this problem, and in some implementations compare-double-and-swap (64-bit...

automatic garbage collection. Any lock-free data structure that uses the compare-and-swap primitive must deal with the ABA problem. For example, in a lock-free...

to the quantity being considered. For example, an algorithm using compare and swap (CAS) on a pointer might use the low bits of the address to indicate...

register is used. A compare-and-swap instruction is even provided in some processor architectures, which compares and conditionally swaps two registers. This...

__sync_bool_compare_and_swap built into many Unix compilers. With the optimizations applied, a sample would look like: ; In C: while (!__sync_bool_compare_and_swap(&locked...

(1991) proved that fetch-and-add has a finite consensus number, in contrast to the compare-and-swap operation. The fetch-and-add operation can solve the...

A credit default swap (CDS) is a financial swap agreement that the seller of the CDS will compensate the buyer in the event of a debt default (by the debtor)...

hardware level requires atomic operations such as Test-and-set, Fetch-and-add, Compare-and-swap, or Load-Link/Store-Conditional, together with memory barriers...

access. Some processors have special instructions, like test-and-set or compare-and-swap, which, by locking the memory bus, can be used to provide mutual...

copy-on-write ("implicitly shared" in Qt's terms). Qt uses atomic compare-and-swap operations to increment or decrement the internal reference counter...

problem is found for lock-free programs on persistent memory. As compare-and-swap (CAS) operations do not persist the written values to persistent memory...

systems, memory paging (or swapping on some Unix-like systems) is a memory management scheme by which a computer stores and retrieves data from secondary...
