چکیده
A solution is presented to the problem of quickly detecting the end of an asynchronous parallel computation, in which processors exchange task request messages asynchronously, and termination occurs when all processors are idle and no messages are in transit. The proposed termination detection scheme is based on a nite automaton consisting of only two states, and one possible transition between states. This solution is superior in many cases to ad hoc solutions such as polling processors periodically to see if they are done, because it is simple, eecient, and has fast response time. Simulation results show that the scheme has low overhead.

“The Slave-Girl Will Give Birth to Her Master” as Understood via “Temple Symbolism”
The so-called Islamic State (ISIS/ISIL) used the hadith mentioning that “the slave-girl will give birth to her master” to justify its renewal of sexual slavery. This hadith is talking about signs before the end of the world, so it could be interpreted by the same Temple theology technique that has been used in the biblical book of Revelation, which is also about the end of the world. “...

In the study, we propose the Associated Probability Intuitionistic Fuzzy Weighted Averaging (As-P-IFWA) and the Associated Probability Intuitionistic Fuzzy Weighted Geometric (As-P-IFWG) aggregation operators with associated probabilities of a fuzzy measure presenting an uncertainty. Decision makers' evaluations are given as intuitionistic fuzzy values and are used as the arguments of the aggre...
متن کاملMaster/Slave Speculative Parallelization with Distilled Programs
Speculative multithreading holds the potential to substantially improve the execution performance of sequential programs by leveraging the resources of multiple execution contexts (e.g., processors or threads). For unstructured non-numeric programs, the three key challenges of parallelization are (1) predicting the sequence of tasks (i.e., groups of instructions) that corresponds to the correct...
متن کاملComputation Efficiency of Master-slave Processors in Multitasking Applications: a Performance Analysis
Examines the computational efficiency of the master slave Multiple processor architectures system by considering a system consisting of a master M and p slave processors. The system performance is found by modelling it as a Markov process and a new method presented for computing the steady-state performance by dividing the state space into an interior and boundary space. The throughput of the s...
متن کاملSynchronization of bilateral teleoperators with time delay
Bilateral teleoperators, designed within the passivity framework using concepts of scattering and two-port network theory, provide robust stability against constant delay in the network and velocity tracking, but cannot guarantee position tracking in general. In this paper we fundamentally extend the passivity-based architecture to guarantee state synchronization of master/slave robots in free ...
