31Main Differences to LCG-2
- Workload Management System works in push and pull
mode - Computing Element moving towards a VO based
scheduler guarding the jobs of the VO (reduces
load on GRAM) - Distributed and re-factored file replica
catalogs - Secure catalogs (based on user DN VOMS
certificates being integrated) - Scheduled data transfers
- SRM based storage
- Information Services R-GMA with improved API
and registry replication - Prototypes of additional services
- Grid Access Service (GAS)
- Package manager
- DGAS based accounting system
- Job provenance service
- Move towards Web Services
32Standards
- Web Services Fast moving area
- Follow WSRF and related standards but are not
early adopters - WS-I compatibility is a target
- Challenging to write WSDL which is WS-I
compatible AND can be processed by all the tools - Industry strength tooling not always available
- Trying to keep back from the bleeding edge
- Work on standards bodies
- Active contributions to
- GGF OGSA-WG
- GMA in OGSA
- Data Design team
- GGF INFOD-WG
- OASIS WS-N
- GGF GSM-WG (SRM)
- Co-chairing WG
- Replica Registration Service
- And following many, many others
- Adopting mature standards is a goal

Need to prepare permanent, common Grid
infrastructure Ensure the long-term
sustainability of the European e-infrastructure
independent of short project funding
cycles Coordinate the integration and interaction

(NGIs) Operate the European level of the
production Grid infrastructure for a wide range

48EGI-InSPIRE
The EGI-InSPIRE project (Integrated Sustainable
Pan-European Infrastructure for Researchers in
Europe) started on 1 May 2010, co-funded by the
European Commission (contract number RI-261323)
for four years, as a collaborative effort
involving more than 50 institutions in over 40
countries. Its mission is to establish a
sustainable European Grid Infrastructure
(EGI). EGI-InSPIRE is ideally placed to join
together the new Distributed Computing
Infrastructures (DCIs) such as clouds,
supercomputing networks and desktop grids, for
the benefit of user communities within the
European Research Area.
