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)

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

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

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 GIS Architecture (test phase) GRIS Implemented Implemented using INFNGRID distribution To be implemented

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

GRID Second step (now) Pre-compiled distribution (available now for Linux Red Hat 6.1): INFNGRID 1.1 /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) Configure GRAM services (6) Globus local deploy (7) GIIS Configuration ==================================================== Condor and LSF

GRID Second step Script for post install operations: globus-root-setup Installation instructions for special environments (configuration of client machines, shared install-directory) included List of included bug fixes Status Tests performed in different environments (INFN, CERN, FNAL) “Officially” released Available to DATAGRID partners (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 (5)Configure gsi-wuftpd and restart the inetd daemon

GRID Next steps Configuration of PBS as local resource management systems: 1.2 Support for Solaris 2.6: 1.2 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 GDMP: 1.2 Inclusion of other GRID software packages ?? Other works will be “triggered” by local administrators and users Some items missing ???

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
