The distribution … GRID This is a report on a preliminary work to create a GRID distribution for INFN. We focused on : GLOBUS 1. 1. 3 Solaris and Red. Hat 5 September 2000 Data. Grid Work. Shop, Marseille 2
The intent … GRID Decrease complexity and the number of errors during install Collect fixes and include them in current distribution Merge necessary changes Setup a mechanism for releasing new versions Create a Globus distribution including INFN customizations. 5 September 2000 Data. Grid Work. Shop, Marseille 3
The INFN customizations… INFN Certification Autority GIS Architecture GRID Dc=infn, dc=it, o=grid Top Level INFN GIIS Exp=cms, o=grid Dc=bo, Dc=infn, dc=it, o=grid GIIS INFN CMS GIIS Dc=mi, Dc=infn, dc=it, o=grid GIIS Bologna 5 September 2000 Milano Data. Grid Work. Shop, Marseille 4
The first step … GRID As a first step we created a distribution: /afs/infn. it/project/infngrid/current (1. 0) We included fixes found during first evaluations. We wrote an INFNGRID installation guide (July 2000): http: //www. pi. infn. it/~flavia/GRID/GLOBUS_INST_113. html We created scripts to make certain steps automatic. globus-root-setup, user-environment, … 5 September 2000 Data.

The Second step … GRID Is it possible to create a pre-compiled distribution ? (We succeeded with standard setup…!? Linux. ) In version INFNGRID 1. 1 we provide a script: infngrid-install (1) Copy INFNGRID tar files from /afs/infn. it/project/infngrid/1. 1/Linux to download dir (2) Decompress and untar INFNGRID distribution files in install dir (3) Configure INFNGRID software (4) Globus Setup (5) Globus local deploy (6) GIIS Configuration ========================== (q) Quit (h) Help ========================== 5 September 2000 Data.

The Second step … GRID Still some steps to be done afterwards … q If you generated a certificate request, please keep the certificates you receive from the INFN CA in a safe place then, rerun the Globus Local Deploy procedure giving the full file name of the certificate and key, or copy the certificate and key to the directory /pool 2/opt/etc. As root, run the procedure : /pool 2/globus/infn-scripts/globus-root-setup to complete the installation. Remember to add user entries to the local grid mapfile using the command grid-mapfile-add-entry You are done for now. 5 September 2000 Data. Grid Work. Shop, Marseille 7
The Second step … GRID Heavy tests needed in different system environments INFN certification procedures need to be settled we are able to generate an INFN certificate request for a gatekeeper inside globus-local-deploy INFN GIIS configuration to be tested Other configuration missing ? (Local resource managers: Condor, LSF, PBS) 5 September 2000 Data. Grid Work. Shop, Marseille 8
The short-term plans … GRID Improvement of current non-precompiled distribution Eventual merge of infn-install script for both pre-compiled and no pre-compiled distributions. We are trying to make it installation “unattended”. 5 September 2000 Data. Grid Work. Shop, Marseille 9
Conclusion GRID The INFN distribution of the GRID software is available now. We are trying to keep it general. Other people doing the same job ? Or interested ? Is this the right way to proceed ? 5 September 2000 Data. Grid Work. Shop, Marseille 10
