operations? So the advantage is not in the operating system itself but in the platform software. Again pull far, eh ... The JDK5 later provided more than 10 atomic classes under the Java.util.concurrent.atomic package. The common atomicinteger,atomiclong,atomicreference and their array forms, as well as the Atomicboolean and the Atomicstampedreference classes introduced to address the ABA problem, Finally, a utility class that is based on reflection

objective-c Attribute Properties (assign, retain, copy, ReadOnly, ReadWrite, Atomic, nonatomic) The following article is reproduced from: http://blog.csdn.net/zhangao0086/article/details/6674460, this article is very thorough, not like other articles so vague, thank the author. Document Address: Property Declaration Attributes section of the OBJECTIVE-C programming Language Assign: Specifies the setter method with a simple assignment,

An atomic operation is an operation that cannot be interrupted during the process. Atomic operation for a value in the process of being carried out, the CPU will never go to another operation for that value.To achieve this rigor, atomic operations are represented and completed only by a separate CPU instruction. The Go language provides

About single CPU, multi-CPU on the atomic operation from http://software.intel.com/zh-cn/blogs/2010/01/14/cpucpu? Cid = Sw: prccsdn956 The so-called atomic operation is "an uninterrupted operation or a series of operations ". Hardware-level atomic operations:In a single processor system (uniprocessor), operations that can be completed in a single command can be c

Introduction to the implementation principle and application of the atomic package in Java, javaatomic 1. Proposal of synchronization problems Suppose we use A dual-core processor to execute two threads A and B, one is to execute thread A, and the other is to execute thread B, both threads now need to add 1 to the member variable I of the object named obj. Assuming that the initial value of I is 0, theoretically the value of I should be 2 after the tw

interrupted at any time. 2) Soft Interrupt and tasklet-internal nuclear power can wake up or schedule Soft Interrupt and tasklet at any time to interrupt the code currently being executed 3) kernel preemption-the kernel may be preemptible by another task. 4) sleep and synchronization with the user space-processes executed in the kernel may be sleep, which will wake up the scheduler and lead to scheduling of a new user process 5) symmetric processor-two or more processors can execute code simult

LockLocks and semaphores are very familiar to most people, especially common mutexes. There are many kinds of locks, mutual exclusion locks, spin locks, read and write locks, sequential locks, and so on, here are just a few things to see,　　　Mutual exclusion LockThis is the most common, Win32:createmutex-waitforsingleobject-releasemutex,linux pthread_mutex_lock-pthread_mutex_unlock,c. #的lock和Monitor, Java Lock, these are mutexes. The role of mutexes everyone knows, is to let a piece of code at t

IntroductionAtom (Atom) is intended to be "the smallest particle that cannot be further divided", while atomic manipulation (atomic operation) means "one or a series of operations that cannot be interrupted". Implementing atomic operations on multiprocessor is a bit more complicated. Let's talk about how atomic operati

guidelines for using atomic packages in Java This paper starts with concurrent network, author: Fang Fei Introduction Java from the JDK1.5 began to provide a java.util.concurrent.atomic package, to facilitate the programmer in a multi-threaded environment, without locking the atomic operation. The bottom layer of the atom variable uses the atomic instructions pr
