Synchronization is often necessary in parallel computing, but it can create delays whenever the receiving processor is idle, waiting for the information to arrive. This is especially true for barrier, or global, synchronization, in which every processor must synchronize with every other processor. Nonetheless, barriers are the only form of synchronization explicitly supplied in OpenMP, and they...

The purpose of the Air Transportation System (ATS) is to provide safe and efficient transportation of passengers and cargo. The on-time performance of the ATS is measured by flight-based metrics such as flight delays and flight cancellations. Researchers have shown that flight-based metrics do not accurately reflect the passenger trip experience, and especially underestimate the impacts of canc...

It has been recognized for some time that nonzero signal rise and fall times contribute to gate propagation delays. Practically, however, most timing analysis tools ignore these contributions when computing path delays and identifying critical paths in combinational circuits. In this paper we describe how these rise and fall times can be incorporated into path analysis algorithms. Interestingly...

in this paper, a bidirectional associative memory (bam) neural network, which consists of two neurons in the x-layer and three neurons in the y-layer, with two time delays will be studied. we conclude that under some assumptions, hopf bifurcation occurs when the sum of two delays passes through a critical value. a numerical example is presented to support our theoretical results.

Random delays are commonly used as a countermeasure to hinder side channel analysis and fault attacks in embedded devices. This paper proposes a different manner of generating random delays, that increases the desynchronisation compared to random delays whose lengths are uniformly distributed. It is also shown that it is possible to reduce the time lost due to the inclusion of random delays, wh...
