Overview
Since the last reviewThe HLA Group has been restructured
The schedule and priorities has been revised
A design methodology has been adopted
We will concentrate on delivering a core suite of applications to replace those on the SCP
Use of the ECLIPSE RCP deferred
Applications will be written in Java, Swing
Working applications: SCORE, bunch length, feedbacks, Matlab applications

Choice of Framework
Matlab has been successfully used to develop many applications for commissioning, so why is it not enough?1. In general, we want to take a longer term view to HLA support (see next slide)2. Specifically, we need to provide an online model that is database driven and linked to EPICS PVs3. Feedback software has reached its limit of complexity in Matlab. Further development needs to be done in Java and C

Software Architecture for HLAsWell developed Application Programming Interfaces (APIs) so that
Code duplication is minimized.Code maintainability is optimized.Applications can integrate with other HLAs.Higher level applications can be built hierarchically from other smaller applications.HLAs can be executed from a script so that whole procedures can be written.
Exception handling, no crashing when unexpected events occur.Multi-threaded for higher performanceCentral message logging that archives system eventsDatabase awareSimilar look and feel for applications, intuitive interface. Choose beamline “sections” (no hard coding to one part of the beamline)unified framework for the application software
share common features such as restoring setups, data saving and access to various software tools on the Operator Interface workstation screens (OPIs)
Matlab can access the APIs so that new applications can be rapidly prototyped by physicist programmers when new physics needs arise.

Evolution of the Architecture
New architecture is not a direct copy of XAL from SNSWe are sharing some of XAL’s features
Java based applications, uses JCA, SMF from the online model, database driven
XAL had many hard-coded instances to specific SNS devicesXAL applications did not meet LCLS requirements exactly

OnLine Model
XAL model installedBeamline generated from the Oracle RDB
In turn generated from the MAD beamline file“live” machine settings are read through EPICS Channel Access Model output is written back to the RDB
Accessible to all programs, including MatlabA Matlab script is currently being used to compare the XAL design model output with the MAD design output.
Inconsistencies are being removed (debugging)

Start to End Simulationsprovide a software script to transfer the multiparticle results from one code to the nextuse the Standard Machine Format description of the accelerator developed for the XAL online model and the database logging tools to supply the “live” machine settings to the input files for each of the simulation codescapture the simulated particle distributions at each of the monitor points of interest along the beamline, such as at profile monitor and wire scanner locations, as well as the undulator output.provide a tool for displaying the simulation results alongside the measured beam profilesanalyze the execution time for complete and partial simulations of the machineevaluate whether the simulation can be displayed in real time alongside the measured machine data using an advanced computing farm.optimize the code to run on the superfast computersor, develop tools whereby snapshots of the machine settings can be easily saved at the time real beam data is recorded so that the snapshots can be used as input for the machine simulations for offline comparison with measured data.
