Atomicstampedreference solves the ABA Problem
There is a classic ABA problem in the lock-free operation using CAS:
Thread 1 is going to use CAs to replace the value of a with B. Before that, thread 2 replaces the value of a with C and C with, when
The thread needs to communicate with each other in the following two cases:
• When multiple threads access shared resources, the resources are not damaged.
• When one thread needs to notify another or more threads of the completion of a task.

1. FormServlet. java designs a form to submit data to prevent users from repeatedly submitting data to the server. The blocking code is as follows:
FormServlet "text/html; charset = UTF-8" = "token", token ); "" "" "User Name: "" ""
Assume that the basic data is:{"Name": "cb", "data": 0 ,}Sometimes, to make full use of multiple cores, multiple node processes are enabled at the same time. However, if some code involves operations on mongodb, the following occurs.Ideally, the
For the TIM5 interrupt handler, make the following explanation. (TIM5 interrupts include both timer update interrupts (timer count overflow), and capture interrupts)

Atom: The word removes the substrings of individual letters, for example, ac bc AB ABC in ABC. Note: Ca does not count.Valid ATOM: an atom with a length greater than 60% of the word length. It can be used for Lenovo memory and similar

C ++ concurreny in Action Chapter 5 Memory Model and atomic operation of C ++5.1 Memory Model BASICS (Internal Model basics)
Memory Model involves two aspects: structural and concurrency
Structural is the foundation, mainly the object layout.
5.1.1 objects and memory location
The C ++ standard defines an object as "a region of storage ,"
Note:
All variables have objects, including member variables.
All objects have their own memory locations.

BackgroundAn atomic operation is an operation that cannot be divided. Atomic manipulation is a very important concept in multi-threaded programs, and it is often used to implement some synchronization mechanisms and is

locking-based algorithms is that if latency has a locked thread (due to page errors, scheduled latency, or other unexpected latency ),NoThe thread to be locked can continue to run.
Variable variables can also be used to store shared variables at a lower cost than synchronization, but they have limitations. Although other variables can be seen immediately, the read-Modify-write sequence of atomic operations cannot be displayed, which means (for exampl
