Description

The dependency meta-package, what is it?

• Experiment software has dependencies
  • Many can be satisfied from the OS
  • Particularly, SL5 provides compat* rpms to enable SL4 applications to run on SL5
• A single metapackage wil be used to install on SL5/64bit WNs which pulls in all necessary OS rpms
  • For SL4 32 and SL5 32/64 apps

Use cases

CMS (Andrea Sciaba’ for Peter Elmer) :

• Preferable to use WN with interactive access (a PPS node at CERN would be OK)
• Can do tests at RAL and GRIF but fail to see the point

LHCb (Roberto):

• No problem to do a quick test

Atlas(Alessandro De Salvo)

• They can try the SW against whatever we propose
• In addition to that they want to download the rpm and try it in a local installation as well
• Observation: this covers requirements for SL5 only. Sites working with Cent)S and Ubuntu will still need explicit list in the VO ID card (they use it)

Alice(Patricia Mendez)

• She thought that Alice had no special requisites on OS
• would like to know exactly the packages specifically introduced for Alice
• cannot do special testing but it Alice is already running on SL5 at RAL
