GRID Goal

Reduce time and manpower for installation and configuration of Globus

• Automize and Standardize the installation of the Globus Toolkit and related packages

• Automize the Globus setup procedure

• Collect and apply bug fixes that are not included in the current version of Globus

GRID Design and implementation

• We distribute the precompiled Globus and related packages together with tools for automatic installation and configuration.

• The toolkit includes two major scripts written in bash: one for installation and the other for the system configuration.

• Modularized design makes standard and specific installation and configuration separate.

GRID Evaluation of the Current Release

• Tested at several INFN sites, CERN and FNAL, ITEP

• Tested on RH Linux 6.1, Sun Solaris 2.6

• Tested for the INFN setup (at INFN sites) and the standard setup (at other sites)

• Reduce complexity and manpower for installation and configuration (5min vs.~1h)

• Problem with machine with alias (we plan to solve it soon)

GRID Report by F.Donno from U.S.(1)

• Globus is forseen to be divided into small packages each of which rebuildable by standard code management tools . (Project to be approved)

• A tool for automatic installation and service configuration is NOT forseen by Globus.

• The INFN Globus installation toolkit is important for providing configuration and service definition to the Globus repackaging project.

GRID Report by F.Donno from U.S.(2)

• The INFN toolkit remains independent from the Globus project but could be accepted by Globus as an official tool of installation and autoconfiguration of Globus.

• If the Globus repackaging project will be approved, future release of INFNGRID will be built on the new structure of Globus.

• Well organised testbeds for the test of Globus and compilation of software on different platforms are welcome.

Open questions for the community

• Should a working frame be defined for the code development? Define common rules for build, for using compilers and libraries….

• Should we have a limitation of platforms for the EU testbeds?

• Token passing problems with jobmanager installed on AFS…

• Exchange patches with other institutes…
