Beeldmateriaal Drechterland Draait Door deel 1Loft25
Op 23 mei 2015 hield de gemeente Drechterland open huis vanwege de feestelijke opening van het nieuwe gemeentehuis in Hoogkarspel. Om het programma op te luisteren, werden twee live talkshows gehouden: Drechterland Draait Door. De ochtendshow werd ondersteund door beeldmateriaal, dat verzorgd werd door Loft25.
Просмотр фильма «Марафон» (De Marathon), с детальным разбором.
На мастер-классе вы узнаете, принципы того:
как превратить скучную и бессмысленную жизнь, в жизнь полную радости
как превращать рутиные дела, в дела приносящие радость и счастье
как быть счастливым, независимо от количества денег в кармане.
Keep Calm and React with Foresight: Strategies for Low-Latency and Energy-Eff...Tiziano De Matteis
This talk has been given at PPoPP 2016 (Barcelona)
The paper addresses the problem of designing control strategies for elastic stream processing applications. Elasticity allows applications to rapidly change their configuration (e.g. the number of used resources) on-the-fly, in response to fluctuations of their workload. In this work we face this problem by adopting the Model Predictive Control technique, a control-theoretic method aimed at finding the optimal application configuration along a limited prediction horizon by solving an online optimization problem. Our control strategies are designed to address latency constraints, by using Queueing Theory models, and energy consumption by changing the number of used cores and the CPU frequency through the Dynamic Voltage and Frequency Scaling (DVFS) function of modern multi-core CPUs. The proactive capabilities, in addition to the latency- and energy-awareness, represent the novel features of our approach. Experiments performed using a high-frequency trading application show the effectiveness compared with state-of-the-art techniques.

A Multicore Parallelization of Continuous Skyline Queries on Data StreamsTiziano De Matteis
Skyline queries are a relevant example of preference queries frequently used in multi-criteria decision making to retrieve interesting points from large datasets. They return the points whose attribute vector is not dominated by any other point. Due to their importance in real-time scenarios, skyline queries have been studied both in terms of sequential algorithms and parallel implementations for multiprocessors and clusters. Recently, with the advent of the Data Stream Processing paradigm, skyline queries have been computed over continuous data streams according to the sliding window model. Although sequential algorithms have been proposed for continuous skyline queries, few works targeting modern parallel architectures exist. This paper contributes to the current literature by proposing a parallel implementation on multicores. We provide a description of our parallelization by focusing on the cooperation pattern between parallel functionalities, optimizations related to the reduce phase, and load-balancing strategies. Finally, we show experiments using different point distributions, arrival rates and window lengths.
