Applied behavior analysis (ABA), also referred to as behavioral engineering, [1] [2] is a psychological discipline that applies the principles of learning based upon respondent and operant conditioning to change socially significant behavior. ABA is the applied form of behavior analysis; the other two are: radical behaviorism (or the philosophy ...
In multithreaded computing, the ABA problem occurs during synchronization, when a location is read twice, has the same value for both reads, and the read value being the same twice is used to conclude that nothing has happened in the interim; however, another thread can execute between the two reads and change the value, do other work, then change the value back, thus fooling the first thread ...
Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed. Lag, as it is known in gaming circles, refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games.
Some CAS-based algorithms are affected by and must handle the problem of a false positive match, or the ABA problem. It is possible that between the time the old value is read and the time CAS is attempted, some other processors or threads change the memory location two or more times such that it acquires a bit pattern which matches the old value.
Wormhole switching is widely used in multicomputers because of its low latency and small requirements at the nodes. [ 3 ] : 376 Wormhole routing supports very low-latency , high-speed, guaranteed delivery of packets suitable for real-time communication .
The ABA's first season was defined by empty stadiums (the league claimed to have averaged over 2,804 attendees per game, but that was, by all accounts, a huge lie), shockingly violent on-court ...
The speed of light imposes a minimum propagation time on all electromagnetic signals. It is not possible to reduce the latency below = / where s is the distance and c m is the speed of light in the medium (roughly 200,000 km/s for most fiber or electrical media, depending on their velocity factor).
Here the sequential latency is same in both single mode and burst mode, but the total initial latency is decreased in burst mode, since the initial delay (usually depends on FSM for the protocol) is caused only once in burst mode. Hence the total latency of the burst transfer is reduced, and hence the data transfer throughput is increased.
