Meetings n 2 Meetings n n n October 12, 2000 November 20, 2000 Agenda n n n Report on on-going/completed tasks Planning activities for next future Next meeting: January 11, 2001

Security (GSI) n n n Script to make host certificate requests easier (done [F. Prelz]) Scripts to manage distribution of CRL (done [C. Rocca]) Management of grid-mapfile updates (work in progress) n n Script to publish user certificates in LDAP server (done [G. Lo Biondo]) Members of groups published in LDAP server (update done by “administrators” of these groups) n n n Web tool to “manage” groups (evaluation of existing tools) (to do [C. Rocca]) Tool (certretrieve) used to query the LDAP server (for example to get the members of a specific group): the results are grid-mapfile entries (done [G. Lo Biondo]) Tests with Kerberos (to do [Milano, Padova])

Information Service (GIS) n n n Implementation of site’s GIISes almost completed Netscape LDAP server as mirror of top level GIIS (work in progress [G. Lo Biondo, G. Vita Finzi, F. Semeria, E. Fasanelli, Ferrara]) Review the information gathered from the various machines and published in the GIS (to do [G. Lo Biondo, G. Vita Finzi, F. Semeria, E. Fasanelli, Ferrara]) Tests on performance and scalability (work in progress [F. Semeria, G. Vita Finzi, G. Lo Biondo, E. Fasanelli, Ferrara]) Tools (MRTG based) to monitor the status of the GIS servers (done [G. Lo Biondo])

GIS Architecture (test phase) Implemented Top Level INFN GIIS Dc=infn, dc=it, o=grid Implemented using INFNGRID distribution To be implemented Exp=atlas, o=grid Dc=bo, Dc=infn, dc=it, o=grid Dc=mi, Dc=infn, GIIS dc=it, o=grid GIIS Bologna Milano INFN ATLAS GIIS GRIS

Resource Management (GRAM) n Tests with CMS HLT n Many many memory leaks in the Globus jobmanager n n n Fixes provided by F. Prelz On-going merge with some fixes provided by Globus team Possible to repeat tests with next CMS productions Tests with GRAM API (to do [F. Giacomini]) Other tests with PBS (done [Torino]) GRAM – GIS “cooperation” (work in progress) n Review and “integrate” the information concerning a FARM published in the GIS n First proposal defined (considering LSF and Condor) (done [M. Biasotto, M. Sgaravatto]) n n Development of scripts for LSF (work in progress [M. Biasotto]) Tests with MPICH-G 2 (work in progress [Alfieri, Spataro]) n n Necessary to integrate this proposal considering also PBS (to do [Milano, Torino]) When ready “submit” the proposal to Globus team MPICH-G 2 vs MPICH Execution benchmarks (work in progress [Torino, F. Giacomini])

Test layout for CMS production Submit jobs Production manager (Ivano Lippi – Padova) condor_submit (Globus Universe) Condor-G Padova globusrun Globus GRAM Local Resource Management Systems Globus GRAM CONDOR LSF Farms Bologna Pisa

Globus deployment n INFNGRID 1. 2 (done [Pisa]) n INFNGRID 1. 1’s functionalities n n Precompiled Globus 1. 1. 3 for Linux Red Hat 6. x gsiwuftpd Support for LSF and Condor as underlying resource management systems Possibility to implement INFN customizations n n n n n Installation instructions Support for Solaris 2. 6 Support for PBS as resource management system Support for GDMP (only for Linux) Tool to upgrade INFNGRID 1. 1 INFNGRID 1. 2 Installation instructions INFNGRID 1. 1. 1 (unofficial release) (done [Pisa]) n n Certificates signed by INFN CA Preliminary architecture for GIS INFNGRID 1. 1 + first (not working) bug fixes for job manager INFNGRID 1. 1. 2 (unofficial release) (done[Pisa]) n INFNGRID 1. 1. 1 + MPICH-G 2

Globus deployment n INFN-GRID 1. 3 (work in progress [Pisa]) n n n n Fixes for Globus jobmanager memory leaks Support for Solaris 7 Full support for GDMP Distribution of various Globus compilations (Kerberos, MPICH-G 2) Perl Certretrieve Other bug fixes Web software repository (work in progress [L. Fonti, G. Vita Finzi]) n n Subscription to mailing list Policies ? ? ? ?

Data Management n Tests with globusftp alpha release 2 (work in progress [Cnaf, Torino, Padova]) n n Collaboration with WP Network Tests with replica catalog software alpha release 2 (work in progress [Pisa, Padova]) n Collaboration with WP Data Management

Futuro del WP 1 n Durata e deliverables dopo 6 mesi (Gennaio 2001 ? ) n n n Tools, documentation and operational procedures for Globus deployment Final report on suitability of the Globus toolkit as basic Grid infrastructure E poi ? ?

Futuro del WP 1 n Obiettivo del WP 1 (Globus) n Prima valutazione del Globus toolkit n n n Cosa puo` esserci utile ? Cosa non funziona/manca ? Cosa va modificato ? NON era previsto di “potenziare”/adattare i servizi di Globus alle nostre esigenze E` utile che si continui a “guardare” a Globus … … ma non crediamo opportuno che questo continui ad essere fatto in un WP “generico” per la valutazione di Globus

Futuro del WP 1 n … piu` opportuno che questo venga fatto nell’ambito dei WP dello sviluppo del middleware (che dovranno scegliere se e come usare questi servizi, ed eventualmente adattarli) n n n Globus Resource Management (GRAM) Workload Management WP Globus Data Management stuff (globusftp, replica catalog software, …) Data Management WP + Network WP Distribuzioni INFNGRID Testbed Security Testbed (come nel progetto europeo) Information Service Testbed (come nel progetto europeo)
