In computer science and software engineering, busy-waiting, busy-looping or spinning is a technique in which a process repeatedly checks to see if a condition is true, such as whether keyboard input or a lock is available. Spinning can also be used to generate an arbitrary time delay, a technique that was necessary on systems that lacked a ...
A pause frame includes the period of pause time being requested, in the form of a two-byte (16-bit), unsigned integer (0 through 65535). This number is the requested duration of the pause. The pause time is measured in units of pause quanta, where each quanta is equal to 512 bit times.
Transactional Synchronization Extensions and other hardware transactional memory instruction sets serve to replace locks in most cases. Although locks are still required as a fallback, they have the potential to greatly improve performance by having the processor handle entire blocks of atomic operations.
Synchronization is designed to be cooperative, demanding that every thread follow the synchronization mechanism before accessing protected resources for consistent results. Locking, signaling, lightweight synchronization types, spinwait and interlocked operations are mechanisms related to synchronization in .NET." [11]
TCP global synchronization in computer networks is a pattern of each sender decreasing and increasing transmission rates at the same time as other senders. It can happen to Transmission Control Protocol (TCP) flows during periods of congestion because each sender will reduce their transmission rate at the same time when packet loss occurs.
Synchronization is the coordination of events to operate a system in unison. For example, the conductor of an orchestra keeps the orchestra synchronized or in time . Systems that operate with all parts in synchrony are said to be synchronous or in sync —and those that are not are asynchronous .
Futures are a particular case of the synchronization primitive "events," which can be completed only once. In general, events can be reset to initial empty state and, thus, completed as many times as desired. [11] An I-var (as in the language Id) is a future with blocking semantics as defined above.
Mobile Networks require a kind of synchronization The aim of Synchronous Ethernet is to provide a synchronization signal to those network resources that may eventually require such a type of signal. The Synchronous Ethernet signal transmitted over the Ethernet physical layer should be traceable to an external clock, ideally a master and unique ...
