Development of the distributed information system for the cooperative work under the design and optimizationof charged particle accelerators

Abstract

A problem of the development of distributed information system for carrying out numerical experiments in the purpose of design and optimizations of charged particle accelerators is discussed. The infrastructure of a considered informational system should provide an effective methods for organizing calculations, storing, sharing, exchanging and analyzing the results of numerical experiments and data, remote user access to the system for group of researchers. To achieve this aim we proposed distributed architecture based on independent components: database server, high-performance distributed calculation services, web interface that provides tools for interaction of users with information system. To ensure flexible changing of models we proposed the ”lazy filling” conception of database table.

Collaborative Optimization Method for Distributed Systems based on Deep Learning

“…The parameter server is responsible for distributing the model and summarizing the gradient, and the worker is responsible for computing and maintaining communication with the parameter server. The updating model can be divided into synchronous updating and asynchronous updating [14].…”

Development Method and Support Tools of Distributed System Based on Web Service

“…In fact, from the different signs of software development, distributed architecture has become an Distributed Processing System inevitable trend [6]. Kane M B introduced a distributed hydraulic control architecture with scalable computation and resilience to component failures in the network and physical domains.…”
