The paper brings forward an idea of multi-threaded computation synchronization based on the shared semaphored cache in the multi-core CPUs. It is dedicated to the implementation of multi-core PLC control, embedded solution or parallel computation of models described using hardware...
We consider the parallel composition of two cyclic programs. The interaction of these programs consists of a form of synchronisation sometimes referred to as 'mutual inclusion'. For a given implementation of this synchronisation by means of semaphore operations, we prove the correctness of the program...

The formats used in this library for the multi-party computation are compatible with the ones used inSemaphore's Perpetual Powers of Tauandother implementations. This library uses the compiled circuits generated by thecircomcompiler. It works innode.jsas well as directly in thebrowser. It's anES...

One way to achieve this property is with a mutual exclusion lock (sometimes called a semaphore). For example, when any process issues a request to perform one of the four deque operations, the first action is to acquire the lock, which has the property that only one process may own it ...
Semaphore is a kind of mechanism used in a multithreaded environment to ensure that two or more key code segments are not concurrently invoked. In order to... Zhu,H Shi - 《International Journal of Grid & Utility Computing》 被引量: 0发表: 2015年 Implementation of PPP Protocol in μC/OS...
In fact,Javaalready comes with a good tool to implement the leaky bucket algorithm, that is,Semaphore, which can effectively control the maximum number of concurrent services and prevent service overload. The following is a typical usageSemaphore ...
We use the semaphore mechanism to prevent simultaneous access. In section 4.4 we present the experiments that were carried out for comparing the above mentioned strategies. 4.4 Test-bed for Studying Serial Line Handling Issues For these set of experiments we have used i286 based PC-AT to run ...
To take advantage of improved performance in semaphore processing, you must be running on hardware that supports the PLO (Perform Locked Operation) instruction. 14 UNIX System Services z/OS Version 1 Release 7 Implementation 1.2.5 Configuration parameters The z/OS implementation of UNIX is different...
