

Globus installed on 5 Linux PCs in 3 sites
(Bologna, CNAF, Padova)
Lots of problems accessing the American MDS server !!!

Problems with automatic population and update of information

Long response time


Time out
Not possible to test other services (i.e. GRAM)



Italian GIS Server @ CNAF
Globus installed on ~ 15 machines in 8 sites
(Bari, Bologna, CNAF, LNL, Milano, Napoli,
Padova, Pisa)

WP “Installation and Evaluation of the Globus
Toolkit” of the INFN-GRID Project
(http://www.pd.infn.it/~sgaravat/
INFN-GRID/Globus)



Goal: evaluate the Globus toolkit as a GRID framework providing basic services

Which services can be useful ?


What is necessary to integrate/modify ?
What is missing ?
Duration: 6 months (2000)

Results of this first evaluation used to plan future activities








Globus deployment
Security
Information Service
Resource Manager
Data Access and Migration
Fault Monitoring
Execution Environment Management



Goal: reduce complexity for installation and maintenance  limiting the manpower
“Central” Globus administrators responsible to:
 implement and maintain a central software repository
 develop tools and documentation to enable local administrators to quasi-automatically install Globus on local resources



Implementation of “local” Certification
Authority

Relations with other CAs
Integration of existing applications with
GSI authentication mechanisms




Tests on performance and scalability

Results used to define and implement the information service architecture
Tools and interfaces for Grid users and administrators
Integrate the default information with other info, provided by specific agents





Job submission on remote resources that don’t rely upon resource management systems
Evaluation of GRAM with (local) resource management systems (LSF, Condor)
RSL as uniform language to describe resources

Translation from RSL to the specific resource description language
“Cooperation” between GRAM and GIS



Evaluation of GASS APIs to access remote files

Adaptation of existing applications
Evaluation of GASS and GSIFTP for data migration in LAN and WAN



Evaluation of services for fault detection for


Globus processes other “system” processes (i.e. http, ams, …)

“user” processes
Data collectors

Detect and notify about failures

Recovery mechanisms (i.e. automatic restart of crashed processes)

Execution Environment Management (GEM)

Evaluation of GEM as service for code migration

 staging of executable location and/or instantiation of runtime libraries



Deliverables

Tools, documentation and operational procedures for Globus deployment (6 Months)

Final report on suitability of the Globus toolkit as basic Grid infrastructure (6 Months)
Milestones

Basic deployment grid infrastructure for the INFN
GRID (6 months)
