Cost-Based Vectorization of Instance-Based Integration Processes

Cost-based vectorization of instance-based integration processes

“…However, it is interesting to note that the fully vectorized solution performs slightly better for small n. However, when increasing n, the cost-based vectorized approach performs optimal. 3 Correction: There was a computation failure in the original presentation of experimental evaluation results [7]. In detail, the execution time was divided twice by the number of repetitions, while the variance was a summation over all repetitions.…”

“…In order to overcome those two drawbacks, in this article (as an extension of [7]), we propose the cost-based vectorization of integration processes. The core idea is to group all m operators of a process plan into k execution buckets, then execute not each operator but each execution bucket with a single thread (all operators of this bucket are executed with the instance-based execution model), and hence, reduce the number of required threads.…”

Algoritmo Baseado na Meta-heurística Particle Swarm Optimization para Configuração de Pools de Threads em Motores de Execução de Plataformas de Integração

“…Na literatura há dois modelos que podem ser seguidos para implementação dos motores de execução; process-based e task-based [Blythe et al 2005, Alkhanak et al 2016, Boehm et al 2011, Frantz et al 2012. No modelo processbased, uma mesma threadé responsável pela execução de todas as tarefas sobre uma mesma mensagem que percorre o processo de integração, e no modelo task-based, distintas threads podem ser usadas para executar tarefas que processam uma mesma mensagem ao longo do processo.…”
