CMSSW

• Basic concept: CMSSW is the current official CMS simulation and reconstruction software framework. There are various modules (shared object files), which are dynamically linked to a main binary (called cmsRun), which is not touched at all by the user. These modules can be switched on/off and can be configured by job config files. It runs like this: cmsRun job_config_file.cfg. One can also say this in an other way: the cmsRun interprets the job config file. One can also extend or modify the software by creating/modifying the modules.
• Some useful links: twiki, software cross reference, config language manual, useful samples.
• How to check out and use: download the files install_cmssw.sh and DemoAnalyzer.tar.gz, then run the install_cmssw.sh install script. Check the directory CMSSW_*_*_*/src/Demo/DemoAnalyzer. Under the bin directory I put a quasi-automated job runner script called go.sh. Under the test directory, there are job config sample files, like: single muon sample generation by particle gun + simulation + digitalization, local reconstruction (hit collection), and CTF-KF track finding.
