As the result of the checking, when the conditions for not establishing the synchronization for some time are judged, a process in the busy wait interrupts the execution of the process by itself, control is shi
Sleep Disadvantage:the orderin which the blocked threads execute the critical section (CS) isleft to chance and the system. The system chooses one of the blocked threads and allows it to execute the code in the CS. Where are we going with synchronization? •There is a better way:...

Synchronization Hardware concept Many systems provide hardware support for critical section code Uniprocessors – could disable interrupts Currently running code would execute without preemption Generally too inefficient on multiprocessor systems Operating systems using this not broadly scalable ...
Thus, migration can benefit a large set of applications in production worldwide. Technically, a BSP application is composed by a set of rounds or supersteps, each one composed by parallel computation on each process, arbitrary communication among them, and a barrier synchronization. In particular,...
The OS supports synchronization mechanisms such as barriers, semaphores, and mutexes, among others, by which two or more processes may order their respective computations to avoid these possible hazards. Processes may directly communicate with each other, passing or exchanging messages or data streams....
Synchronization Synchronization macros are useful in the multithreaded build environment, which build.exe uses by default. During build.exe's execution, these macros ensure that modules that have dependencies are not built until those dependencies are satisfied. Build.exe generally handles dependencies...
