3 Why/When FROG? October 2007 November 2007 January July 2008 Now I wanted to show to my friends and family what HEP is. But I was not able to run Iguana without crashes (remote site). In my free time, I started an Event Displayer (Simulated Data) It works but is full of bugs and can display only in 3D. My colleague Vincent Roberfroid, discovers the event display And was so enthusiast that he convinced me that it is useful. He joined the team, and we decided to name it FROG! FROG starts to be really functional, and can display objects in many different views. Anyone can add easily new objects, etc. It was used by Christophe Delaere for Cruzet3. FROG is now able to run on online data, and in the cms center. Future??? stay tuned on the FROG Website : 09/01/ IPNL Lyon - UCL - CP3 Loïc Quertenmont - loic.quertenmont@uclouvain.be 3

4 The Frog Philosophy FROG decouples display and physics computations FROG is a Free Toolkit based on OpenGL and a few other common libraries FROG can be used easily in any experiment : From very small experiments up to large LHC experiments FROG is written in C++ FROG uses files in a compact binary format FROG is really Fast and Intuitive FROG has two main components : The Displayer : Used to display the experiment s geometry and event e data The Producer : The Interface between The Displayer and the experiment software! FROG Displayer is compatible with Linux, Windows and MacOS. FROG doesn t require HEP specific libraries like ROOT! (Good for Outreach) This allows 100% of flexibility and portability FROG can also work online with a constant data flow! The weight of the complete FROG package is arround 4MB 09/01/ IPNL Lyon - UCL - CP3 Loïc Quertenmont - loic.quertenmont@uclouvain.be 4

26 Delphes

27 Introduction Delphes is a framework for the Fast Simulation of a General Purpose Collider Experiment. The simulation includes the usual components of such detector as well as possible very forward detectors arranged along the beamline. The framework is interfaced to standard le formats (e.g. Les Houches Event File) and outputs observable analysis data objects, like missing transverse energy and collections of electrons or jets. The simulation of detector response takes into account the detector resolution, by smearing the kinematic properties of the particle. Usual reconstruction algorithms are applied for complex objects, like the missing transverse energy or the jets originating from b quarks or leptons. Delphes contains a specific (embedded) FROG Producer that can be used to display the simulated events.

32 How to run FROG

33 How can I display events? On a Local Computer? yes no Frog will be slow More details on the FROG Displayer page 3D trough SSH is always slow LXPLUS via SSH OS? Windows Linux Mac Did you setup already a CMSSW project with FROG? yes no Download FROG_1_106.zip Unzip FROG_1_106.zip Open FROG_1_106 Double click on frog.exe You will have to install few libraries If not installed yet : OpenGL, GLUT, X11-devel and CURL. Download FROG_1_106.tar.gz tar -zxf FROG_1_106.tar.gz cd FROG_1_106 make./frog You will have to install the Mac developement framework Open a clean terminal (eval `runtime ` creates interferences with FROG) cd /Visualisation/Frog/soft make./frog 09/01/ IPNL Lyon - UCL - CP3 Loïc Quertenmont - loic.quertenmont@uclouvain.be 33

34 What are the FROG Performances? No particular hardware are needed Any <5 years old computer should be ok. it has been tested in an internet café without any troubles VGA Card : Better is faster ;-) Some Numbers using my home desktop computer : AMD3800+ with 2Gb DDR RAM and a Geforce7600GT (256Mb) Cosmic events (CRAFT) Initialisation Time Next Event Time Live Memory Used FramesPerSecond ~3sec <<1sec ~ 80Mo ~500FPS (in general limited to 60/70FPS by the VGA Card itself if you want to the real FPS number, you only have to switch off VSYNC in your VGA Card Options). 09/01/ IPNL Lyon - UCL - CP3 Loïc Quertenmont - loic.quertenmont@uclouvain.be 34

35 Config.txt or How to setup Frog Because Frog is experiment independent need to be configured in a txt file. Default file works fine for CMS! #Include = Config/CMS_Colors.txt; #Include = Config/CMS_Views.txt; Those files Are described in next slides InputVisFile = { InputGeom = { ActiveViews = {ViewMenu,View3D,ViewTra,View2DR,View2DZ}; // Current event number Event_Number = 0; // if -1, the event shown is the last event in the.vis file.

38 How to get the.vis. Files?

vis file database that contains many cosmic runs You only need to copy the URL

39 How to get the.vis. files There are two Possibilities 1. Download an already existing.vis file : In CMS, there is a.vis file database that contains many cosmic runs You only need to copy the URL of the file in the FROG s config.txt file 09/01/ IPNL Lyon - UCL - CP3 Loïc Quertenmont - loic.quertenmont@uclouvain.be 39

40 How to get the.vis. files 2. Create the.vis file yourself with a Frog Producer : Example to run the CMS FROG Producer Setup your CMSSW Project project CMSSW scramv1 project CMSSW CMSSW_2_1_10 cd CMSSW_2_1_10/src cvs co -r Version_1_104 -d Visualisation/Frog UserCode/FastOpenGlDisplayer scramv1 b cd Visualisation/Frog eval `scramv1 runtime -csh` (or eval `scramv1 runtime -sh`) cd python Edit your CMSSW cfg file and run it There are already 3 demo files in the Frog/python/ directory : Frog_Analyzer_cfg.py (for MC data) Frog_Analyzer_CosmicsFrowReco_cfg.py (for cosmic data from RECO) Frog_Analyzer_CosmicsFrowRaw_cfg.py (for cosmic data from Raw) There is nothing to change in those files except the process.source, the BField, the GlobalTag. cmsrun Frog_Analyzer_cfg.py Two files have been produced in the Frog/python/ directory: CMS.Geom.gz Cosmics_cosmictrackfinderP5Filter_Run66533_1stEvent vis.gz 09/01/ IPNL Lyon - UCL - CP3 Loïc Quertenmont - loic.quertenmont@uclouvain.be 40

41 How to get the.vis. files 3. Use a Web Service (not yet functional) In Collaboration with the Caltech CMS Group, we are currently developing a pilot FROG Web Service for CMS GOAL : Get a specific.vis without installing CMSSW and other tools INPUT : DataSet, Run#, Event Cuts/Filters, list of objects that have to be stored OUTPUT : a.vis(.gz) file and/or a FROG Config.txt file Specificity : the Tool will be hosted on Caltech Server, if requested.vis file do not exist, it will be produced and stored on the server If it exist, the link will be given to the user Mail alert when file is available (should be fast if dataset is available at Caltech) if dataset is not stored locally, job will be launched over the grid. 09/01/ IPNL Lyon - UCL - CP3 Loïc Quertenmont - loic.quertenmont@uclouvain.be 41

42 How can I run Frog Online?

43 FROG Online Nothing is easier : just run the Producer and the Displayer Simultaneously Edit Config.txt InputVisFile = {../python/inlive.vis}; Event_Number = -1; Always show the latest event Event_Time = 1; Reload events every 1sec to load latest produced events Launch FROG (file InLive.vis doesn t exist yet it s not an issue!)./frog In a second terminal, launch the event processing with CMSSW cd /Visualisation/Frog/python eval `scramv1 runtime (c)sh` cmsrun Frog_Analyzer_CosmicsFromRaw_cfg.py That s it, while the cmssw job is running, events will be pushed in a temporary.vis file Named InLive.vis. When the file is full, or job is finished : File will be renamed (and gzipped)! 09/01/ IPNL Lyon - UCL - CP3 Loïc Quertenmont - loic.quertenmont@uclouvain.be 43

45 Conclusions FROG : it s Fast, it s Simple, and it Works Slowness is not a fatality for 3D Event Display Useful for commissioning and debugging of algorithms It can be used live during a meeting Outreach You can add yourself new displayable objects. Tutorial available here You can use it for other experiments Tutorial available here 09/01/ IPNL Lyon - UCL - CP3 Loïc Quertenmont - loic.quertenmont@uclouvain.be 45
