20.500.12556/DKUM-57755 Implementacija distribuiranega sistema alarmov za pospeševalnik delcev fair s pomočjo vzporednega modela aktorjev in koncepta agentov The Implementation of the Distributed Alarm System for the Particle Accelerator FAIR Using an Actor Concurrent Programming Model and the Concept of an Agent Sistem alarma je sklop programske opreme, ki omogoča skrbnikom prepoznavo že nastalih napak na strojni ali programski opremi in odkrivanje napak, ki bi se lahko pojavile v prihodnosti kot na primer pregrevanje magneta na pospeševalniku. Sistem alarm FAIR je nastal kot slovenski doprinos pri izgradnji pospeševalnika delcev FAIR. Glavni namen magistrskega dela je v prikazu poenostavitve razvoja visoko razpoložljivega distribuiranega sistema alarma s pomočjo uporabe sočasnega (angl.Concurrent) programskega modela aktorjev in uporabe agentov. Agent loči distribucijo signalov alarma do odjemalcev od samega procesiranja. Odjemalci se namreč nikoli ne povežejo neposredno na sistem alarma, ampak se povežejo nanj preko agentov. Logična komunikacija med odjemalcem in agentom je preko aktorja v odjemalcu in aktorju, ki je v agentu. Ta dva aktorja si izmenjujeta protokolarna sporočila preko javanskega sporočilnega sistema. V magistrskem delu bomo prikazali hierarhično strukturo aktorjev, ki se uporablja za napake odporno komunikacijo med aktorji in njihova protokolarna sporočila. Zanimalo nas je tudi, kako je procesni del sistema alarma povezan z distribucijskim delom, ki ga sestavljajo agenti in odjemalci. The Alarm System is a software system that enables operators to identify and locate conditions of hardware and software components which indicate malfunctioning or nearby malfunctioning (e.g. an overheated magnet). The FAIR Alarm System is being constructed as a Slovenian in-kind contribution to FAIR project. The purpose of the paper is to show how to simplify the development of a highly available distributed alarm system for the particle accelerator using a concurrent programming model based on actors and on the concept of an agent. The agents separate the distribution of the alarm status signals to the clients from the processing of the alarm signals. The client never connects directly to the alarm system but through an agent. The logical communication between an alarm client and an agent is between an actor in the alarm client and an actor in the agent. These two remote actors exchange protocol messages through Java Message Oriented Middleware. The following will be addressed: the tree-like hierarchy of actors that are used for the fault tolerance communication between an agent and an alarm client; a custom message protocol used by the actors; how is the alarm processing subsystem connected with the actors and agents (distribution subsystem); the message system and corresponding technical implications; and details of software components that were developed using the Akka programming library. visoko razpoložljiv distribuiran sistem alarma sočasni programski model aktorjev koncept agenta na napake odporna hierarhična struktura aktorjev ločitev distribucije signalov alarma od procesnega dela modeliranje in simulacija highly available distributed alarm system a concurrent programming model based on actors the concept of an agent a fault tolerant tree-like hierarchy of actors Separation of the distribution from the processing of the alarm signals Modeling and simulation true true false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2016-03-15 11:38:40 2016-06-03 15:38:54 2022-06-15 03:08:46 2019-07-11 10:17:18 2016 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 7603987 URN:SI:UM:DK:6KWDLQZY MAG_Kumar_Damjan_2016.pdf MAG_Kumar_Damjan_2016.pdf 1 AB7024ADFC2F2D62ACC34C344AE342B9 20cf7ba4eb4ccf5e2c6a7682affe342b2fe7d55c86128ac7d22737bdcf26b80b f93d1d39-7c0b-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=87229 Fakulteta za organizacijske vede 0 0 0
