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

Glasgow

The SL5 meta package is installed on our cluster and if our experiments would like to test at our site I can open up the CE to accept requests.
