  1. The Virtual Data Toolkit Alain Roy VDT

  2. What is the VDT? • A packaging of software • Grid software (Globus, Condor-G…) • Virtual data software (Chimera) • Utilities • An easy installation mechanism • Pacman: installs and configures it all • RPM: for some of the software VDT

  3. Who makes the VDT? • Grid Physics Network (GriPhyN) • Constructs the VDT • International Virtual Data Grid Laboratory (IVDGL) • Testing and hardening • Very tight collaboration between GriPhyN and IVDGL VDT

  4. Who makes the VDT? (2) • Core VDT Team: • Miron Livny: The boss • Alain Roy • Carey Kireyev • VDT Testing • Xin Zhao • Brian Moe • Pacman • Saul Youssef VDT

  5. Who uses the VDT? • GriPhyN collaborators • USCMS: In use today • USAtlas: In use today • LIGO: Will use soon • SDSS: Will use soon • European Data Grid (Including INFN) • Uses subset of software (patched) • Uses just RPMs • Strong collaboration and feedback • LCG VDT

  6. What exactly is in VDT? • VDT 1.1.8: • Globus 2.2.4 + advisories + patches • Condor & Condor-G 6.5.1 • MyProxy • Chimera/Pegasus • RLS • GLUE Schema • CA Certificates • Fault Tolerant Shell • EDG’s Make Gridmap • EDG’s CRL Update • ClassAds • Netlogger VDT

  7. Pacman Installation • Goal: • Type a single command • Everything downloads • Everything installs • Everything is configured • No questions asked • We’re close: • A few questions if you’re root • Basic configuration, may need changing VDT

  8. Pacman Installation (2) • Download Pacman • http://physics.bu.edu/~youssef/pacman/ • Install VDT • cd <install-directory> • pacman -get VDT-Server • pacman -get VDT-Client • ls condor/ globus/ post-install/ setup.sh edg/ gpt/ replica/ vdt/ ftsh/ perl/ setup.csh vdt-install.log • Use VDT

  9. Pacman post-installation • Post-install directory: • Notes on configuration choices made • Instructions for editing configuration • Configuration scripts: • Globus configuration (different from EDG) • Condor configuration VDT

  10. RPM Installation • Subset of whole VDT • Globus • Condor-G • Nice RPMs: • We repackage Globus • A dozen Globus RPMs, not hundreds • No configuration • No post-installation help VDT

  11. Testing • VDT team is building test suite • Interaction with LCG testing group • Working with NMI* to leverage: • NMI test suite • Stress testing • Application testing (CMS pipeline) • NMI test infrastructure • NMI = NSF Middleware Initiative • http://www.nsf-middleware.org VDT

  12. Support • Send us questions or problems • We will solve them if we can • We will interact with the developers, if necessary VDT

  13. Interaction with EDG/LCG • EDG and LCG get Globus and Condor-G RPMs from VDT • We do what we can to solve problems and get changes to Globus and Condor • We want to make a great package for EDG/LCG! VDT

  14. VDT’s Future • Access to new versions • Globus 3.0 • Extra VDT to help early adopters • Will not supplant main version for a while • Helping You • What can we do to make life easier for you? VDT

  15. Where do you learn more? • http://www.griphyn.org/vdt • Support: • vdt-support@ivdgl.org • Alain Roy: roy@cs.wisc.edu • Miron Livny: miron@cs.wisc.edu VDT
