Title: Testbed: Status


1
Testbed Status Plans
  • Charles Loomis (CNRS)
  • Sept. 5, 2002
  • 5th Project Conference (Budapest)
  • charles.loomis_at_cern.ch
  • (See http//documents.cern.ch/age?a021246 for
    trans.)

2
Software Status
  • EDG 1.2.0
  • Deployed on application testbed.
  • 20 time-limit on jobs high-rate submissions
  • Other bugs replica manager, GDMP replication
  • EDG 1.2.1
  • Deployed on application testbed (CERN,
    Karlsruhe).
  • No time-limit low-rate submissions.
  • Other bug GDMP replication
  • EDG 1.2.2
  • To be tagged when GDMP rpm tested.
  • No time-limit low-rate submissions.

3
Testbed Status
  • Application Testbed (formerly Production
    Testbed)
  • EDG release 1.2.0 deployed on six sites.
  • CC-IN2P3, CERN, CNAF, Karlsruhe, NIKHEF, RAL.
  • Actually split into two parts
  • 1.2.0 no GASS Cache hack long jobs, low
    submission rate
  • 1.2.0 proper 20 limit on jobs, high submission
    rate
  • But, migrating to 1.2.1/2.
  • ATLAS tests in progress ? See F. Harris WP8
    talk.
  • Development Testbed
  • EDG 1.2.1 installed.
  • Testing 1.2.2 today.

4
Sites
  • Six main sites currently participating.
  • CERN, CNAF, Karlsruhe, Lyon, NIKHEF, RAL
  • See transparancies for individual status.
  • THANKS!
  • Markus Schulz, Emanuele Leonardi, Alessandro
    Cavalli, Andrea Chierici, Alessandro Italiano,
    Markus Hardt, Fabio Hernandez, David Groep, Jeff
    Templon, Steve Traylen
  • Beginning to see real computing power available.
  • Storage beginning to ramp up as well.
  • Around 15 others waiting to join.
  • Other grid projects (CrossGrid, GridPP, INFN
    Grid,)
  • More still once some national CAs are approved.

5
Certification Authority Group (D. Kelsey)
  • CAs are under control.
  • Acceptance procedure working.
  • Added German CA Greece made report Poland
    Slovakia by email.
  • Min. requirements updated (RA procedures Online
    CA with special hardware.)
  • Scalable for future?
  • Procedures for establishing trust are quite
    involved.
  • ATLAS raised issue about length of time to obtain
    approval.
  • Cross-domain trust.
  • Will participate in CA Operations group in GGF.
  • Kerberos-based CAs
  • CERN and FNAL interested with this.
  • VO Authorization Issues.

6
Authorization Group (L. Gaido)
  • Currently use LDAP-based membership services.
  • Will have grid-proxy-init with vo option.
  • Inserts VO-name into proxy subject.
  • Requires patch to Globus code and change to
    mkgridmap.
  • Available 30 Sept. 2002.
  • VO Membership Service (VOMS)
  • Inserts membership info into proxy as optional
    attributes.
  • Client command (voms-proxy-init), Server, and
    migration tools exist.
  • API Admin. tools available 30 Sept. 2002.
  • Real shift in the way we do VO-authorization.

7
Other Projects
  • NorduGrid (Balazs Koyna)
  • Good communication though overlap of people.
  • Grid Manager replaces gatekeeper, smart
    input/output staging
  • User Interface contains built-in brokering.
  • Info. System based on MDS, includes job
    monitoring, user-specific info.
  • CrossGrid (Markus Hardt)
  • Close collaboration between EDG CrossGrid
    testbed groups.
  • Significant contributions to CA group.
  • Globus
  • Support shaky (distracted by OGSA, fixes supplied
    by others)
  • Find EDG effort to support/fix Globus full-time.
  • Reduce dependencies on Globus as much as possible.

8
Globus Version
  • Globus 2.1.2
  • Has fix from CONDOR of GASS Cache problem.
  • Lot of work to apply to beta-21.
  • Includes many additional changes job manager.
  • WP1 logging patches no longer work.
  • Whole LRMS backend changes to perl framework.
  • Globus 2.2
  • Exists, but
  • Some question about what is happening with the
    MDS 2.2 in this.
  • Will make Globus Release-24 and test.

9
Short Term Plans (I)
  • EDG 1.2 series NOT suitable for widespread
    deployment.
  • EDG 1.2.0
  • Available now, known limitations.
  • EDG 1.2.1
  • Deploying now long jobs, low submission rate.
  • Deploy multiple resource brokers to reduce
    problem.
  • EDG 1.2.2
  • GDMP replication fix.
  • Done today? Quick upgrade for sites at 1.2.1.
  • EDG 1.2.x
  • Other critical fixes, but very high threshold
    now.

10
Short Term Plans (II)
  • EDG 1.3 series will be widely deployed.
  • EDG 1.3.0
  • Upgrade Globuswill contain GASS cache patch from
    Condor.
  • Hopefully will also have MDS 2.2.
  • Subject to testing, will be deployed on
    application testbed.
  • EDG 1.3.x
  • Clean up LCFG objects/configuration.
  • Modify setup to support new developer guidelines.
  • EDG 1.4.x
  • Begin incremental inclusion of new middleware
    packages.

11
Rolling Release
  • Autobuild procedure will run daily
  • On all supported platforms (RH6.2, 7.2 now)
  • To build, package, and unit test HEAD version of
    modules.
  • Feedback information to developers.
  • Middleware developers
  • Use development machines to test software.
  • Tag package when ready for integration.
  • Schedule time on development testbed to test
    package.
  • ITeam
  • Current baseline release ? Add test package ? New
    baseline release.
  • Will use acceptance test suite to determine if
    package is included.

12
Autobuild Procedure (Y. Patois)
  • On RH6.2
  • All but 5/30 packages build and are packaged
    without errors.
  • On RH7.2
  • Around 10/30 packages fail the make install
    step.
  • All fail make rpm because of rpm command
    change.
  • Warning
  • Wont integrate packages unless autobuild
    procedure works.

13
Testing Group (G. Merino)
  • Cooperation between testing groups (combine?)
  • TSTG
  • INFN EDG Testing Group
  • CrossGrid test/validation group.
  • LCG
  • Testing Group
  • Goals
  • Testing of EDG services.
  • Validation of new site installation
    configuration.
  • Methodology
  • A priori definition of features to be tested.
  • Collect tests from group and from others.
  • Keep framework and tests in CVS.

14
Documentation
  • Release Notes
  • Exist for 1.2.0 (will be updated for 1.2.1).
  • Users Guide
  • Exists, but should be considered draft.
  • Comments welcome ? please use Bugzilla for this.
  • Installation Guide
  • Wont be rewritten until Globus upgrade.
  • LCFG configuration files up-to-date ? must move
    this to Installation Guide.
  • Tutorial materials also available.
