  1. UCL Testbed 1 status report Paul Mealor GridPP Meeting, Cambridge, 15 Feb 2002 Paul Mealor, UCL

  2. pc15 laptops UI GIIS pc18 SE pc23 CE GRIS GRIS Machines Imperial RB RAL country GIIS GridPP Meeting, Cambridge, 15 Feb 2002 Paul Mealor, UCL

  3. Installation • Used the Kickstart mechanism from Andy McNab • Started with a very early version of Globus and EDG software • Upgrading machines (somewhat slowly) to V1.0.0 (or V1.1.0 when lists become available) GridPP Meeting, Cambridge, 15 Feb 2002 Paul Mealor, UCL

  4. Job submission • Submitting jobs to the RB at IC • Simple jobs successfully run, submitted to a CE at IC from one of the three TB1 machines at UCL • Teething problems • Can’t get the results back! • This may be because of version differences • Uses the EDG software GridPP Meeting, Cambridge, 15 Feb 2002 Paul Mealor, UCL

  5. Job submission • Using the RB at IC to submit jobs (cont…) • Work ongoing • progress is good so far • will hopefully be able to register CEs at UCL with the RB GridPP Meeting, Cambridge, 15 Feb 2002 Paul Mealor, UCL

  6. Job submission • Also tried Globus job submission system • RAL and Bristol • Not so much success • Not concentrating on this anyway, as Globus system does not include sandboxes &c. GridPP Meeting, Cambridge, 15 Feb 2002 Paul Mealor, UCL

  7. Job submission • Other tests • Java GRAM interface (Janice Drohan) • Still under development • Attempts to interact with Globus 2 gatekeeper • Successfully submits jobs to our local CE GridPP Meeting, Cambridge, 15 Feb 2002 Paul Mealor, UCL

  8. Globus MDS • Machines successfully registering to the UCL GIIS • GIIS successfully registering to the RAL country GIIS. • When it was up, the Datagrid GIIS at CERN showed metadata from UCL! GridPP Meeting, Cambridge, 15 Feb 2002 Paul Mealor, UCL

  9. Ftree MDS • Machine metadata successfully cached by UCL GIIS • GIIS has appeared at the Ftree country GIIS at RAL GridPP Meeting, Cambridge, 15 Feb 2002 Paul Mealor, UCL

  10. CE • Installed up to the point of telling it where PBS was to be found… • MDS produces some errors in the tree which look sensible • PBS is being installed as we speak GridPP Meeting, Cambridge, 15 Feb 2002 Paul Mealor, UCL

  11. SE • No luck yet • Original version of TB1 we installed didn’t really work • SE will probably be the last machine to be reinstalled GridPP Meeting, Cambridge, 15 Feb 2002 Paul Mealor, UCL

  12. MDS • Other checks • Java info-system browser (Janice Drohan) • Looked at various GRISs and GIISs (at UCL, RAL, CERN) • Some problems since most recent version of TB1 installed at UCL • Extra EDG info seems to confuse queries • Globus has “mds-vo-name=local,o=grid” naming context • EDG “o=grid” naming context has “mds-vo-name=local” below it GridPP Meeting, Cambridge, 15 Feb 2002 Paul Mealor, UCL

  13. MDS GridPP Meeting, Cambridge, 15 Feb 2002 Paul Mealor, UCL

  14. END GridPP Meeting, Cambridge, 15 Feb 2002 Paul Mealor, UCL
