Applications software management
m R3.1: Software deployment via CVMFSo Adopt for use as shared software area at all WLCG
sitesP Tier1 and Tier2
o Robust and redundant infrastructureP Not yet the case, e.g. manager machines not on safe
power

Middleware Configuration, Deployment and Distribution
m Would like pre-compiled UI distribution that is binary compatible with LCG-AA platform+compiler+python
P e.g. SLC5 + gcc 4.3 + Python 2.6P e.g. SLC6 + gcc 4.6 + Python 2.6 (or 2.7 later)
o Installed in LCG-AA software shared area
o Including agile process for requesting and releasing patches
P Ability to request specific patches to a given released without waiting for next release cycled without picking up new features of next release
P e.g. ROOT deployment model:d Root 5.30.xx
Patches on 5.30, kept alive even after 5.32 release

Monitoring
m 1.4 Streamline availability calculation and visualization
o LHCb supports proposal of one system for visualization and a single availability calculation
o LHCb does not want to be tied exclusively to an external system for running experiment specific tests
P Require a gateway to inject experiment view of availability coming from experiment information system
P Take advantage of advanced monitoring already available in DIRAC without re-implementing it in another system
