CAs and synchronized application scenarios1, for less resources competition, using synchronized synchronization lock for thread blocking and wake-up switching and user-state kernel state switching operation additional waste of CPU resources, and CAS based on hardware implementation, do not need to enter the kernel, do not need to switch threads, the operation spin probability is less, Therefore, higher p

Exchange Server 2010 uses a role-based management model. Multi-Role Server installation and configuration, we have in the previous article has been introduced. In this case, depending on high availability, we need to deploy the server roles on separate servers and achieve high availability of CAs, HT, and MBX roles. At this point, my plan is to deploy two Cas/hub servers first, and then make the two

Overview Single sign-on is mainly used for multiple system integration, that is, in multiple systems, users need to log on to one central server at a time to access any one of these systems without having to log on multiple times. This article uses the Open source framework Jasig CAS to complete a single sign-on. Download Address: Https://www.apereo.org/cas/download Deploying Servers This article server u

[SSO single-point series] (4): Return of user information after cas server logon, ssocas Next, in the previous article, we described how to add a verification code on the cas server logon page and log on. Once the cas server is successfully verified, we will jump to the client. After you jump to the client, let's think about it. The client always needs to obtain

Cas,compare and swap is a technique that is often used to design concurrency algorithms by comparing and replacing them. CAS has three operands: Memory value V, old expected value A, value B to be modified, if and only if the expected value A and the memory value of V are the same, the memory value is modified to B and returns true, otherwise nothing is done and returns false.The general principle of

Lockless programming and CAS lockless programming/lock-free/non-blocking synchronous lockless programming, that is, variable synchronization between multiple threads without the use of locks, that is to say, variable synchronization is implemented when no thread is blocked, so it is also called non-blocking synchronization ). The non-blocking synchronization solution is called non-blocking algorithm ). Lock-free is currently the most common implementa
