1. GRID The GRID distribution toolkit at INFN Flavia Donno (INFN Pisa) Andrea Sciaba` (INFN Pisa) Zhen Xie (INFN Pisa) presented by Massimo Sgaravatto (INFN Padova)

2. GRID The intent … Tools to enable local administrators to deploy the GRID software (now Globus 1.1.3 and related packages: OpenLDAP, …) Reduce complexity and manpower necessary for installation Decrease errors during installations Collect bug fixes Include INFN customizations

3. GRID INFN customizations Certificates (for hosts and users) signed by INFN CA … but user certificates signed by Globus CA are accepted as well Preliminary architecture for GIS (Grid Information Service) Tests on performance and scalability needed to define the GIS architecture

4. Dc=bo, Dc=infn, dc=it,o=grid Bologna GIIS INFN ATLAS GIIS GIIS Dc=mi,Dc=infn, dc=it,o=grid Exp=atlas, o=grid Top Level INFN GIIS Dc=infn,dc=it, o=grid Milano INFN GIS Architecture (test phase) GRIS

5. GRID First step (July 2000) Software distribution available on AFS Fixes for bugs found during first Globus evaluations included INFNGRID installation guide Instructions for INFN customizations included Scripts to make certain steps (i.e. post- install operations) automatic

6. GRID Second step (now) Pre-compiled distribution (available now for Linux Red Hat 6.1) /afs/infn.it/project/infngrid/1.1 Script for installation and deployment: infngrid-install Users decide to use INFN customizations or “standard” setup Would you like the INFN setup (Y/N) ? (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

7. GRID Second step Script for post install operations: globus-root-setup Installation instructions (http://www.pi.infn.it/GRID/GRID_INST_1.1.html) Instructions for special environments (configuration of client machines, shared install-directory) included List of included bug fixes Status Tests performed in different environments (INFN Pisa, INFN Padova, CERN, FNAL) “Officially” released in a few days Would you like the INFN setup (Y/N) ? (1)Modify system files and reactive the inetd daemon (2)Change owner to root of certain files for tighter security (3) Modify system wide login files Support for HEPIX included (4) Start/restart Globus now

8. GRID Next steps Configuration of local resource management systems (LSF, Condor, PBS): very soon Support for Solaris 2.6: very soon We don’t plan (at least now) to support other platforms Improvement of current no-precompiled distribution Eventual use of infngrid-istall script for both pre- compiled and non pre-compiled distribution “Unattended” installation Management of updates Inclusion of other GRID software packages (i.e. GDMP) ?? Other works will be “triggered” by local administrators and users

9. GRID Conclusions The distribution of the GRID software (now Globus) is available We are trying to keep it general (not only for INFN) Useful “tool” to make installation automatic and simple Difficult to integrate with ASIS/SUE Modification of Globus packaging is necessary first Other info on Globus activities within INFN: http://www.pd.infn.it/~sgaravat/INFN-GRID/Globus
