2. A. Aimar - EP/SFTLCG - Software Process & Infrastructure Project context of LCG SPI LCG Application Area LCG Infrastructure Common services Similar ways of working (process) Tools, templates, training General QA, tests, integration, release LCG Application Area software projects POOL: Persistency SEAL: Core common software PI: Physics Interfaces Simulation Detector Description …etc… LHC grid software applications (LHC experiments, projects, etc) LCG SPI project

3. A. Aimar - EP/SFTLCG - Software Process & Infrastructure Project context of the LCG SPI “Software Management Process RTAG” General recommendations -All LCG projects must adopt the same set of tools, standards and procedures -Adopt commonly used open-source or commercial software where available -Avoid “do it yourself solutions” -Avoid commercial software that may give licensing problems If each project needs an infrastructure, many projects need it even more… -Tools, standards and procedures -Try to avoid complexity

4. A. Aimar - EP/SFTLCG - Software Process & Infrastructure Infrastructure Software Development Keep it “simple and modular” a. Provide general services needed by each project -CVS repository, Web Site, Software Library -Mailing Lists, Bug Reports, Collaborative Facilities b. Provide solutions specific to the software phases -Tools, Templates, Training, Examples, etc. Coding Analysis and Design Development Release Specifications Testing ….. Deployment and Installation ….. Planning General Services Software Development

46. A. Aimar - EP/SFTLCG - Software Process & Infrastructure Conclusions Homogeneity is important for the LCG and for its projects Help people to move from project to project or work across projects  common structure, same tools, etc Common services are avoiding many annoying tasks to projects  software library, repository A single users/developers entry for multiple projects  projects portal SPI’s address is  http://spi.cern.ch
