Nominal Technologies for Modelling and High Level Applications of LCLS Greg White 15-Nov-2004 July 28, 2019

Nominal Software Technologies Matlab Ad-hoc analysis Physics Applications Eclipse SWT/Jface Application Framework for Interactive CS Applications (SCP) Eclipse IDE, collaborative software development XAL Modelling components XAL (XML-RPC), AIDA (CORBA), JCA Data Interoperability cmlog, Err Error handling, logging and browsing ESD Unix Development Environment (make,cvs) Building, source repository Oracle Enterprise RDB OC4J, Jboss Application Server Java Programming Language Linux, OS X, Windows Desktop O/S Linux, Solaris Server Hosts O/S NFS Production Host Filesystem AFS Development Host Filesystem This list comprises the target, not the immediate list. That is, it does not include the short and medium term necessity of the existing SCP applications and SLC Modelling system, nor the transition period. July 28, 2019

Eclipse Framework Schematic Applications implemented as Eclipse plugins and features, using Matlab for plotting and interactive analysis. July 28, 2019

AIDA Is middleware for complex data interaction Basic Architecture Model server data (Dimad, Pepoptics, XAL) Control System data (eg SLC db, SLC BPM, EPICS CA …) History Data (SLC History Facility, EPICS Archiver) Basic Architecture Distributed Client/Server with intelligent directory service Language and O/S independent Advantages Fast structured data acq (~2-10ms) Facilitates Application reimplementation and renewal by separating the application from the data source, so you can (re-)write applications on diff O/S before their data sources are moved.

Hopes and Dreams Same modelling codes used for offline analysis and design as online (Elegant/XAL?) Matlab used for plotting and ad-hoc analysis in on-line production control system applications Eclipse framework used for applications “Err” system, on top of cmlog, used for error handling. Eclipse update system used for collaborative development (EPICS 2010 for high level apps) Thought given to which summary displays should be implemented in HTML or some other web technology.
