is a package manager in ATLAS Code
Distribution System. It manages the web-visible cached repository of
distribution kits, handles the dependencies between kits,
transports the kits, installs and configures them through post install
scripts. At Tier I Center the latest versions of Pacman are installed in
/afs/usatlas.bnl.gov/software/pacman area. The U.S. ATLAS
users have an option to use the special script setup_pacman_usatlas.[c]sh
that helps to setup Pacman properly:
This script sets the http proxy for pacman operations, selects the recent version of Pacman installed at BNL and corresponding version of Python.
ATLAS distribution kits are very large for having all of them
on AFS. At Tier I Center the pacman snapshots of recent releases
("optimized") are installed in directories with releases names in
BU-ATLAS:DC2-Base collection (with command
pacman -get 8.0.2:AtlasRelease-opt -allow-tar-overwrite).
Currently the snapshots are available for the following "optimized" releases:
|8.0.4||Pacman Outlook page|
|8.2.0||Pacman Outlook page|
We plan to maintain fully functional mirror of CERN's ATLAS cache
as soon as the mirroring technique is provided by the ATLAS Code Distribution
