  2. LCG externals • A (huge) collection of tools and libraries used in the LCG / AA environment • Tar balls available for each package • We have setup this space in order to • Have control over the versions used • Provide the tools and libs in a unique way • Be able to provide a coherent set of binaries • Allow users to try out new packages

  3. Current Status • All LCG / AA external s/w available in a flat dir structure in /afs/cern.ch/sw/lcg/external • Currently (Mar ‘07) • ~ 120 packages • ~ 520 versions • ~ 2000 binary installations • ~ 300 GB of disk space

  6. Current Status (ctd.)

  7. Problems • Manage flat directory space • Identify used packages • Package management • Installation of new packages • Install new versions of a package • Install a new platform for a given version

  8. Proposal IMove ROOT • ROOT is managed / treated / used as any other LCG / AA project • The reorganization is the perfect opportunity move to the “release” area/afs/cern.ch/sw/lcg/app/releases/ROOT • Symbolic links shall be kept for some time for backwards compatibility

  9. Proposal IIIntroduce hierarchy • Have a handful of categories e.g. • Math • Grid • Tools • Scripting • … • Easier browsing / management • Users browsing on the file system level • For dynamically produced web pages

  10. Proposal IIIIdentify used packages • Vers.1 (the nice one) • Circulate a list with all packages to all “users” of LCG / AA / externals who will select the used packages (and responsible persons) • Vers. 2 (brute force) • Remove/rename packages and wait if it is still needed re-rename it (this way also responsible persons can be identified)

  11. Proposal IVOne source of information • Currently the info about external packages is stored in two places • Seti: A set of xml file for building a package • Extsoft: A mysql database to extract the info for web-pages • We shall have one source from which we derive all needed info • Build instructions • Web pages • Package dependencies • Use / extend the existing database solution
