GrAT
Grid Application Test (GrAT) origins:
• GrAT is originated by the exigency to enable
new tests for the emerging and existing
applications of each Virtual Organisation
• GrAT is designed to aid site-managers and
GOC to test installed grid applications.

submitted to Italian sites
using a web interface.

Grid Service Infrastructure
snapshot
The Grid Service Infrastructure is distributed as much as possible in
different sites. In this way:
– More back-up solutions
– More Fault Tolerance
– No bottlenecks
•
Each site which hosts a grid service must guarantee:
– Dedicated and compatible hardware with software requirements.
– Support for any kind of trouble in the declared response time
•
Operations:
– The local site administrator install and configure the grid service according to
release notes
– The Grid Service Management Team certifies the grid service
•
The Grid Service Management Team can provide grid services ad hoc
– BDII with a particular set of sites
– Resource Broker for particular activities
•
Failure discovering
– GridICE
– Ticket System
