THE INFN GRID PROJECT
Scope: Study and develop a general INFN computing infrastructure, based on GRID technologies, to be validated (as first use case) implementing distributed Regional Center prototypes for LHC expts: ATLAS, CMS, ALICE and, later on, also for other INFN expts (Virgo, Gran Sasso ….)
Project Status: Outline of proposal submitted to INFN management 13-1-2000 3 Year duration Next meeting with INFN management 18th of February Feedback documents from LHC expts by end of February
(sites, FTEs..) Final proposal to INFN by end of March
INFN & “Grid Related Projects”
Globus tests“Condor on WAN” as general purpose
computing resource“GRID” working group to analyze viable
and useful solutions (LHC computing, Virgo…)
Global architecture that allows strategies for the discovery, allocation, reservation and management of resource collection
Local management ([email protected])Steering committeesoftware maintenance contract with
Condor_support team of University of Madison
INFN-GRID project requirements
Networked Workload Management:- Optimal co-allocation of data and CPU and network
for a specific “grid/network-aware” job- distributed scheduling (data and/or code migration)- unscheduled/ scheduled job submission- Management of heterogeneous computing systems- Uniform interface to various local resource
managers and schedulers- Priorities, policies on resource (CPU, Data, Network)
usage- bookkeeping and ‘web’ user interface
Networked Data Management:- Universal name space: transparent, location
independent - Data replication and caching- Data mover (scheduled/interactive at OBJ/file/DB
granularity)- Loose synchronization between replicas- Application Metadata, interfaced with DBMS, i.e.
Objectivity, …- Network services definition for a given application- End systems network protocol tuning
Project req. (cont.)
Application Monitoring/Management:- Performance, “instrumented systems” with
timing information and analysis tools - Run-time analysis of collected application events- Bottleneck analysis- Dynamic monitoring of GRID resources to
optimize resource allocation- Failure management
Project req. (cont.)
Computing Fabric and general utilities for a global managed Grid:
- Configuration management of computing facilities - Automatic software installation and maintenance- System, service, network monitoring and global
alarm notification, automatic recovery from failures- resource use accounting- Security of GRID resources and infrastructure usage- Information service
