Ассоциативная распределенная вычислительная система

В данной работе представлены результаты проектирования ассоциативной распределенной вычислительной системы для решения сложных задач на базе вычислительных устройств с ограниченными техническими параметрами. Для этой цели, решаемая задача разбивается на подзадачи, где для решения каждой подзадачи выделено отдельное вычислительное устройство. Структура вычислительной системы представляет собой локальную сеть с топологией “общая магистраль”. Каждое вычислительное устройство в сети сохраняет имя процедуры решения подзадачи. В качестве примера взаимодействия вычислительных устройств в сети, представлен пример решения простой задачи и ее описание в виде диаграммы последовательностей.In this paper the design of an associative distributed computing system for complex problems solving based on computing devices with limited technical parameters is presented. For this purpose, the problem under consideration is divided into subtasks. For each subtask solving, a separate computing device is allocated. The computer system is organized as a local area network with common bus topology. Each computing device in the network retains the name of the procedure that solved the certain subtask. As an example of the computing devices interaction in the network, a simple task and its description in the form of a sequence diagram is presented

An Extension of the ASC Language Compiler to Support Multiple Instruction Streams in the MASC Model Using the Manager-Worker Paradigm

In this paper, we describe and implement compiler extension for a parallel computer language called Associative Computing (ASC) language to support multiple instruction streams in a Multiple Associative Computing (MASC) model using manager-worker paradigm. A user directed MASC directive is used to enable concurrent executions of the THEN part and the ELSE part in a parallel IF- THEN-ELSE statement by using two different worker- instruction streams. For most applications, this technique should substantially improves the performance of the system over its performance using only one instruction stream; moreover it is more effective than using multiple instruction streams to execute every parallel IF-THEN-ELSE statements found in a program. When the overhead outweighs the benefit gained from using multiple instruction streams, a user can choose to use only one instruction stream to execute the IF-THEN-ELSE statement. While not explicitly covered here, parallel CASE statements can be handled similarly.</p
