Autonomous Decentralized Systems concurrently work on different types of jobs which consist of interdependent tasks ("steps"). Steps are characterized by their service requirements. It is the load balancing problem to increase the system throughput by reducing contention between steps accessing the same resources. In this paper, we propose a dynamic decentralized look-ahead scheduling algorithm...

This paper presents NetStep, a prototype for the distributed simulation of very large scale network simulations, such as the simulation of peer-to-peer applications. We use simulation micro-steps as a means for optimizing the overlap of communications and computations, without changing the original event-driven model. As a consequence, NetStep allows for the reuse of unmodified existing sequent...

PM10 constitutes a major concern for Milan air quality. We presents a series of results obtained applying different neural networks approaches to the PM10 prediction problem. The 1-day ahead prediction shows a satisfactory level of accuracy, which may be further improved if a proper deseasonalization approach is adopted, thus transferring some a priori knowledge in the data pre-processing step....

One well known approach to mitigate the impact of branch mispredictions and cache misses is to enable deep lookahead so as to overlap instruction and data supply with instruction processing. A continuous look-ahead process which uses separate thread of control on another hardware contexts is one such approach which we call decoupled look-ahead [1], [2]. However, in such look-ahead schemes, look...

This paper presents an alternative to process migration , called competition, to speed up distributed programs in the background on a network of processors. Competition protocols are transparent operating system facilities that involve creating multiple instances (called clones) p 1 , p 2 , etc. of a process P on diier-ent processors, and making clones \compete", i.e., attempting to guarantee t...

In this paper we propose a relatively simple procedure to predict Euro-zone industrial production using mostly data derived from the business surveys of the three major economies within the European Monetary Union (France, Germany, and Italy). The basic idea is that of estimating business cyclical indicators to be used as predictors for the industrial production in France and Germany; as far as...

Abstract Energy risk management requires an efficient prediction of CO2 future prices. We apply a neural network calibrated stochastic model to predict day ahead future prices suitable for risk management with a given time horizon (e.g. 10 business days). The model is training neural perceptron layers to learn the weights of historical time series points within a past horizon equal to the the m...
