Over the past two decades the research community has developed a body of knowledge concerning “Lock-Free” and “Wait-Free” algorithms and data structures. These techniques allow concurrent update of shared data structures without resorting to critical sections protected by operating system managed l...
注意,所有WaitFree的程序都是LockFree的。 java.util.concurrent.ConcurrentLinkedQueue是WaitFree思想实现的一个例子。 0x05 更多资料 Lock-Free Programming 0xFF 参考文档 What’s the difference between lockless and lockfree? Examples/Illustration of Wait-free And Lock-free Algorithms Non-blocking algorithm ...
Lock-free algorithms are carefully designed data-structures and functions to allow for multiple threads to attempt to make progress independently of one-another. This means that you do not try to acquire a lock before performing your critical region. Instead, you independently update a local copy ...
in lock-free algorithms under x86 we use for example a lock instruction in assembler, and it's in fact a lock that we are using. It's the lock-free algorithm that is different , you retry when the transaction( the lock..) fails, like in TM. Regards, Amine Moulay ...
How to make any object thread-safe with the speed of lock-free algorithms safe_ptr.h contains C++ code of: safe_ptr<> - make any your custom object thread-safe, even when passed to a function contention_free_shared_mutex<> - 10 X times faster than std::shared_mutex contfree_safe_ptr...

While attending the session a couple of things occurred to me. Firstly, I thought it was about time I reviewed the current status of Java lock implementations. Secondly, that although StampedLock looks like a good addition to the JDK, it seems to miss the fact that lock-free algorithms are...
Michael-Scott非阻塞队列(lock-free)算法的C实现 Michael-Scott非阻塞队列算法,即MS-queue算法,是1 9 9 6 年由Maged . M .Michael and M. L. Scott提出的,是最为经典的并发FIFO队列上的算法,目前很多对并发FIFO队列的研究都是基于这个算法来加以改进的。在共享内存的多核处理器上,这种基于Compare-and-swap(...
