Next meeting: January 11, 2001
Security (GSI)



Script to make host certificate requests easier (done [F. Prelz])
Scripts to manage distribution of CRL (done [C. Rocca])

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)



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)





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

Resource Management (GRAM)

Tests with CMS HLT

Many many many memory leaks in the Globus jobmanager






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)

Review and “integrate” the information concerning a FARM published in the
GIS

First proposal defined (considering LSF and Condor) (done [M. Biasotto, M.
Sgaravatto])




Development of scripts for LSF (work in progress [M. Biasotto])
Tests with MPICH-G2 (work in progress [Alfieri, Spataro])


Necessary to integrate this proposal considering also PBS (to do [Milano, Torino])
When ready “submit” the proposal to Globus team
MPICH-G2 vs MPICH
Execution benchmarks (work in progress [Torino, F. Giacomini])


Tools, documentation and operational
procedures for Globus deployment 

Futuro del WP 1

Obiettivo del WP 1 (Globus)

Prima valutazione del Globus toolkit






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

… 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)

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)
