Summary: This essay aims at developing, implementing and assessing a framework allowing the writing of parallel applications in Octave. The framework will be targeted at the simul- taneous evaluation of multiple instances of the same function with different parameters. The functionality of the frameworks is inspired in MATLAB’s Parallel Computing Tool- box, namely the parfeval function that uses an asynchronous model of computation. The system is developed using Oct-Files that allow the extension of the functionality of Octave; these extensions allow the communication between the Octave interpreter and an infrastructure built in Python that supports parallel executions. The parallel in- frastructure allows the exploitation of both shared-memory multiprocessors and clusters. The system has been evaluated using traditional embarrassing-parallel applications and its performance is good, if we’re able to ensure that the computations last for a time significantly greater than the overhead startup.

A framework tem como alvo a avaliação de múltiplas instâncias da mesma função, mas com diferentes parâme- tros. As funcionalidades da framework são inspiradas pela Parallel Computing Toolbox do MATLAB, mais especificamente a função parfeval, que usa o modelo de computação assíncrono. O sistema é desenvolvido através do uso de Oct-Files que permitem a extensão das funcionalidades do Octave; extensões estas que permitem a comunicação entre o inter- pretador de Octave e uma infraestrutura, construída recorrendo a Python que suporta execução de computações paralelas. Pretende-se que a infraestrutura paralela seja utili- zada em processadores de memória partilhada e ainda em clusters. A framework foi avaliado utilizando técnicas tradicionais de computação tipicamente embarrasingly parallel, e o desempenho do mesmo é boa, desde que se garanta que as computações que irão ser executadas têm uma duração significativamente maior que o overhead do lançamento da infrastrutura e comunicações.Medeiros, PedroRUNCandeias, Miguel Balão2024-05-14T14:34:39Z2022-122022-12-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10362/167376enginfo:eu-repo/semantics/openAccessreponame:Repositórios Científicos de Acesso Aberto de Portugal (RCAAP)instname:FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiainstacron:RCAAP2024-05-22T18:21:29Zoai:run.unl.pt:10362/167376Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireinfo@rcaap.ptopendoar:https://opendoar.ac.uk/repository/71602025-05-28T17:52:01.482010Repositórios Científicos de Acesso Aberto de Portugal (RCAAP) - FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiafalse
