data flow model

data flow model
= data-flow model
модель [организации вычислений] на основе потоков данных
в отличие от модели "ведущий-ведомый" (master/slave model) предусматривает распределённое управление распределённым исполнением приложений в многомашинной или многоядерной системе, - когда задание (работа) передаётся с одного ядра на другое, как на конвейере. Каждое ядро - это ступень обработки данных с использованием различных алгоритмов. Приложения, соответствующие требованиям подобной модели, обычно имеют большие и сложные для вычислений компоненты, которых взаимозависимы и не могут быть исполнены одним ядром. Основная проблема приложений, использующих такую модель, - рациональное распределение компонентов по ядрам и обеспечение высокой скорости прохождения потоков данных в системе. Для этого зачастую приходится разбивать компоненты на части - чтобы можно было задействовать большее число ядер и создать более равномерную загрузку конвейера
