(Short) WP6 Update

This update provides information on the progress of Testbed 0 and the planning underway for Testbed 1, including the software integration process document and upcoming quarterly report. It also requests the names of contributors to Testbed 0 and beyond. Additionally, it discusses the need for wider participation in Testbed 0, the UK-compatible INFN installation kit, and the integration process for Testbed 1. It highlights the need for flexibility in scheduling, resource allocation, and documentation, as well as issues between WP4 and WP6 on installation. The update also mentions the GridPP project and the need for a flexibly partitionable Grid Prototype.

  1. (Short) WP6 Update • Where are we? • Testbed 0 going (ish); some UK sites being tried out for production (mostly LHCb, CMS starting). • Testbed 1 planning underway; debate currently raging • Deliverable 6.1: Software integration process document • Quarterly report due soon (late…) • I need names of all those who have contributed to TB0 + beyond! • Credit where credit is due! • Not a lot of progress on organisation… but leaders are emerging. • Meetings • “April” WP6 meeting postponed until yesterday • Excellent UK attendance, with important contributions Dave Newbold, University of Bristol 21/3/2001

  2. Testbed 0 • In the UK • Several sites are ‘stable’ • Others want to participate • ‘Skeleton’ is now there to try interoperability tests • Documentation is coming (if not from WP6, need UK docs) • New ‘UK’ rpms out + UK-compatible INFN installation kit • Does anyone want to try out INFN kit? • Wider context • Need to make sure other TB0 main sites can accept UK certificates • Is this done? • Need to get production GRID use onto the testbed if possible • e.g. CMS still using GLOBUS certificates… Dave Newbold, University of Bristol 21/3/2001

  4. Testbed 1 • Software integration process • http://marianne.in2p3.fr/datagrid/documents/protected/Testbed_SW_Integration • A long and complex piece of work • …but somewhat controversial from the PoV of other WP • Testing + integration procedure is very rigorous, possibly unworkably complex • ‘Offline discussion’ taking place • Particularly at issue: simulators for middleware modules • Requirements from other WP: • Coming in now; seems practical to accommodate them • Possible a more flexible approach needed for testing (e.g. WP2) Dave Newbold, University of Bristol 21/3/2001

  5. Testbed 1 (cont) • Some personal comments: • Need a more lightweight approach • More flexible scheduling leading up to big releases (but difficult – the cracks in the schedule are appearing) • More flexible resource allocation for complex middleware tests (e.g. WP2) • Need better documentation (ball is probably in our court) • UK has responsibility for translation / vetting! • Schedule: WP8 possibly to delay deliverable by 3 months • Who will participate in TB1 integration from UK? • Unfunded WP6 effort? • What about support / packaging / GRID operations? • Important that we are ready at PM9 Dave Newbold, University of Bristol 21/3/2001

  6. Comments on WP1-7 plans • WP1-5,7,8 presentations yesterday • Good, useful input • Too many comments to relay here • The experts are in the (virtual) room – talks coming up! • A few things I picked up (no thanks to VRVS) • WP8 schedule is impossible w.r.t that of WP6 • Waiting on input from QA people on release procedure / config control • What is the WP7 + WP5 situation in the UK? • Authentication scheme is still a point of discussion? • Some issues between WP4 / WP6 on installation • Presentations are on the web Dave Newbold, University of Bristol 21/3/2001

  7. Testbed + GridPP • Probably not the time for a long discussion • GridPP has ‘Grid Prototype’ + ‘Software Support’ WG’s • These are really different aspects of a testbed: • But ‘TB manager’ from DataGrid PoV maps more closely to SS • SS being led by Andy McNab • We must accommodate DataGrid TB plans + running experiments + data challenges + etc etc etc • All have conflicting requirements • Need a ‘flexibly partitionable’ Grid Prototype • How to achieve integration? • Read the GridPP proposal + comment to Andy McNab / me • Turn up for the meeting on the 24th to discuss • Volunteer to make a contribution Dave Newbold, University of Bristol 21/3/2001
