JAIDA, AIDA-JNI, JAS3 Status and Plans Mark Dönszelmann, Tony Johnson, Joseph Perl, Victor Serbo, Max Turri AIDA Workshop CERN July 2003 Contents JAIDA – Java Implementation of AIDA Part of FreeHEP Java library AIDA-JNI – C++ interface to JAIDA JAS3 – Experiment, Data Format independent graphical data analysis tool based on JAIDA JAIDA, AIDA-JNI, JAS3 July 2003 JAIDA JAIDA = Java implementation of AIDA Complete implementation of AIDA interfaces With a few exceptions – limited support for plot styles currently – Some missing features in ITree, cp, mv Uses Java “service provider mechanism” for dynamic loading of services at Runtime Can be used to add support for new fitters, stores etc. Have defined “developer level” interfaces for IOptimizer, IStore etc Uses Java Expression Library (JEL) for runtime compilation of expressions (for tuple evaluators and functions) JAIDA, AIDA-JNI, JAS3 July 2003 JAIDA – Features continued… Fitting support for multiple fitting engines (optimizers) Support for multiple fitting methods Stores LeastSquares, Chi2, CleverChi2, BinnedMaximumLikelihood and UnbinnedMaximumLikelihood Read/Write support for AIDA XML format (with built-in gzip) Read support for HBOOK/PAW files (needs hbookAdapter native library) Read support for Root files (write support hopefully coming soon) Future plans to add: Plotting UNCMIN (pure Java) Minuit (needs minuitAdapter native library) SQL interface, JDO interface, text file support … Two implementations of IAnalysisFactory BatchAnalysisFactory – dummy plotter, ignore calls to IPlotter AnalysisFactory – Full plotter functionality – limited user input, for full GUI use JAS3 Multi-Threaded – plots update in real-time as they are filled No need to call interact() or refresh() Support for embedding plotter In other Java GUI’s In Java servlets for web based applications. Graphics export in many formats including: PDF, EPS, SVG, SWF, PNG, GIF, JPG JAIDA, AIDA-JNI, JAS3 July 2003 Using JAIDA with Java JAIDA, AIDA-JNI, JAS3 July 2003 Using JAIDA with Python JAIDA, AIDA-JNI, JAS3 July 2003 Using JAIDA with C++ JAIDA, AIDA-JNI, JAS3 July 2003 AIDA-JNI C++ interface uses AIDA-JNI AIDA- JNI AIDA AIDA C++ program JAIDA AIDA-JNI partially generated by AID, partly by hand Does not currently support full AIDA functionality AID improvements (v 0.9.5) coming soon JNI Adapters generated to interface with JACE generated code JACE (JNI made easy) version 1.1 code generates connector to allow access from C++ to Java AID generates code to implement the AID interfaces using the JACE generated code JAIDA, AIDA-JNI, JAS3 July 2003 Future Plans for JAIDA Complete implementation of missing features Continue to track improvements to AIDA standard Add support for function arithmetic Web Interface (see later talk) Support for “Remote AIDA” (see later talk) Support for more storage formats Need good binary IO format .. either AIDA standard or roll our own JAIDA, AIDA-JNI, JAS3 July 2003 JAS3 Overview A completely new version of JAS Design based on Application Shell, into which many (optional) modules can be plugged Highly customizable for different application domains – HEP/Astrophysics/Other – DST analysis/Online Monitoring/GRID analysis – Experiment/User specific modules Modules can be updated independently of shell – Possible to release bug fixes fast Includes support for programming in many languages Scripting: Python, Pnuts, Dynamic Java, …. – Command prompt Java (compiled) Analysis (histograms, tuples, fitting) based on AIDA standard Not technically backwards compatible with JAS2 But migration is straightforward. JAIDA, AIDA-JNI, JAS3 July 2003 JAS3 and AIDA JAS3 supports all AIDA functionality, including Histograms (includes arithmetic, projections, etc.) Clouds (unbinned histograms, scatterplots) Plotter Tuples Fitting – AIDA interfaces allow for multiple fitters Uncmin -- pure java minimizer Minuit -- Fortran called by Java Native Interface (JNI) IO AIDA XML, PAW, Root JAS3 supports user interaction with AIDA in three ways Scripting (Pnuts, Python etc) Compiled (Java) code GUI – Plotting, Fitting, Cuts etc. JAIDA, AIDA-JNI, JAS3 July 2003 JAS3 Scripting JAS3 has multi-language OO scripting support Command line, Console, Editor Major components (e.g. AIDA) have scripting interfaces Currently have plugins to support Pnuts – syntax almost identical to Java, fast, well documented and feature complete Python (using Jython) More scripting languages can be added not restricted to Java implementations (e.g. could use C-Python, JPE) JAIDA, AIDA-JNI, JAS3 July 2003 JAS3 Lightning Tour Tour designed to give you an overview of the capabilities of JAS3, you can try them out for yourself this afternoon. Welcome Page, gives initial info and links to example scripts and programs JAIDA, AIDA-JNI, JAS3 Memory monitor July 2003 Opening Files Use file menu Drag from explorer JAIDA, AIDA-JNI, JAS3 July 2003 Graphical Interface to AIDA Histograms, Clouds, Tuples all presented in AIDA tree .aida files, .hbook files, .root files all presented as AIDA objects JAIDA, AIDA-JNI, JAS3 July 2003 Drag items onto page, or use (popup) menus Printing Or copy/paste into Word, PowerPoint etc. Can send individual plots or full page direct to printer JAIDA, AIDA-JNI, JAS3 Or save as PS, EPS, PDF, SWF, SVG, PNG, GIF… July 2003 Java Editor, Compiler and Loader Tree shows loaded programs Built-in Java compiler JAIDA, AIDA-JNI, JAS3 Built-in editor for writing analysis code Unlike JAS2 which only supported “event analyzers” JAS3 allows any Java program to be loaded. This example “main routine” is July 2003 taken directly from the AIDA manual Scripting Can also write and run scripts Console allows direct interaction with scripting language JAIDA, AIDA-JNI, JAS3 July 2003 Pnuts Language Currently favour Pnuts scripting language Complete and well documented http://javacenter.sun.co.jp/pnuts/doc/guide.html Fast (although not as fast as compiled Java) Syntax very similar to Java Can easily call compiled Java classes from scripts – best of both worlds JAIDA, AIDA-JNI, JAS3 July 2003 Record Sources Opening record (or event) based files causes the run control toolbar to appear JAIDA, AIDA-JNI, JAS3 Works similarly to JAS2 Job control, but now also supports random access and “tagged” data sets (mainly for event displays) July 2003 Tuple Explorer - Plots Histogram Works with any tuple, read from file or dynamically created ScatterPlot XY Data (More appropriate for smaller data sets) JAIDA, AIDA-JNI, JAS3 July 2003 Profile Tuple Explorer – Define Columns JAIDA, AIDA-JNI, JAS3 July 2003 Tuple Explorer - Cuts JAIDA, AIDA-JNI, JAS3 July 2003 Tuple Explorer - Tabulate JAIDA, AIDA-JNI, JAS3 July 2003 Tuple Explorer – Record Source To be used with record loop JAIDA, AIDA-JNI, JAS3 July 2003 JAS3 Spreadsheet Simple spreadsheet plugin for Displaying results Calculations Simple Plots Supports reading/writing .csv files Excel files Cut/Paste with Excel etc Coming Soon… Scripting interface GUI for building plots User defined functions – Java, scripting JAIDA, AIDA-JNI, JAS3 July 2003 Miscellaneous Features Save/Restore configuration User Preferences Plugin Manager JAIDA, AIDA-JNI, JAS3 July 2003 Status Currently released JAS3 version 0.7.1 AIDA functionality is quite solid Compiler, Loader, Record Loop all quite recently added, Certainly still some rough edges Documentation limited but available Built-in example scripts and programs Tutorial on web If you are used to JAS2 you will find some functionality not yet ported to JAS3 Remote (client/server) access to data. 3D Lego/Surface plots JAIDA, AIDA-JNI, JAS3 July 2003 JAS 2 – GRID interface (Tech-X) JAIDA, AIDA-JNI, JAS3 July 2003 JAS and the GRID We plan to add client-server/distributed capabilities to JAS3 similar (but better) than those in JAS2 Will be based on (remote) AIDA Want to use Grid standards where they exist Work with others (PPDG-CS11,???) to define standards where they do not exist Want to be compatible with C++ servers But don’t want to loose flexibility of dynamically loading analysis code into server Tech-X have phase II SBIR approved and will work closely with us JAIDA, AIDA-JNI, JAS3 July 2003 JAS3 Links, More Info JAS – Java Analysis Studio - http://jas.freehep.org JAS3 – http://jas.freehep.org/jas3 JAIDA – http://java.freehep.org/jaida/ AIDA – http://aida.freehep.org FreeHEP - http://www.freehep.org FreeHEP Java Libraries - http://java.freehep.org WIRED – http://wired.freehep.org JAIDA, AIDA-JNI, JAS3 July 2003
