The question is how to run multi-dimensional Lipschitz Global Optimization in parallel, such that the implementation depending on the used platform is efficient. Previous work shows a parallel version developed for multicore nodes with two levels of parallelism: intra-node and inter-node. On intra-node level, one can perform dynamic load balancing by generating threads dynamically. Threads end when they complete their assigned work. The inter-node level carries out a static load balancing using MPI. In general, algorithm design depends on the characteristics of problems to be solved. There are several ways to improve performance of general parallel B&B algorithms. Specifically, we are interested in how to apply them to parallel Lipschitz Global Optimization algorithms. Operations like selecting the next subproblem to be evaluated become critical in parallel B&B schemes. We study Depth and Hybrid (Best-Depth) options as selection criterion. Previous work, using only MPI or OpenMP, discard not only the broadcasting of the best found upper bound of the solution due to its high average cost/performance but also the use of dynamic load balancing. Here we check how broadcasting the upper bound affects the developed MPI-Pthreads algorithm. Additionally, we study how to perform dynamic load balancing at inter-node level. Experimental results show which designs perform better on which type of instances for the used computational architecture.","PeriodicalId":209674,"journal":{"name":"2013 Eighth International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126349615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, those applications are often written for Programmable Logic Controllers (PLCs) in one of the supported modeling languages such as structured text, ladder diagrams and grafcets. The consequences of this approach are that (1) PLC experts are needed to develop the application, (2) it is difficult to verify the application's correctness and (3) when introducing other technologies such as embedded micro controllers, even more experts are needed. This paper proposes an MDE development process that addresses these problems. The use of a domain specific language eliminates the need for PLC experts, and developers can concentrate on the development of the building automation application. Models of the system or a transformation of those models to Discrete Event System Specification (DEVS), State chart, or Causal Block Diagram (CBD) formalisms can be used to verify, simulate and optimize the application based on user needs. In a last step, the code for the target platforms can be generated directly from the verified and optimized models.","PeriodicalId":209674,"journal":{"name":"2013 Eighth International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127995800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Large monitoring applications require proper methodologies and tools supporting the design, when multiple solutions increase the complexity of this task. Indeed, different parameters affect the performance of a solution, as node distribution, sensing coverage, battery usage, etc. A compositional modelling approach can provide early measures, allowing to evaluate and compare different solutions since the design phase. The main contribution of the paper is the definition of a general modelling framework to integrate simple models representing the main components and features of sensor networks. A library for specific sensor devices have been developed, using the Stochastic Activity Network (SAN) formalism. This approach is shown to be compositional since the creation of complex networks can be accomplished by simple subcomponents aggregation. With this approach, obtained models can analyse the dynamic evolution of the overall network, even if complex. First experimental results are also reported and discussed.","PeriodicalId":209674,"journal":{"name":"2013 Eighth International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114384996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
