BNL Mirror of ATLAS Pacman Cache

Pacman is a package manager in ATLAS Code Distribution System. It manages the 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 script setup_pacman_usatlas.[c]sh helps to setup Pacman properly:

       source /afs/usatlas.bnl.gov/scripts/setup_pacman_usatlas.[c]sh

(It sets the http proxy for pacman operations, selects the recent version of Pacman installed at BNL and corresponding version of Python).

The BNL pacman mirror cache holds the recent ATLAS software releases. It is located in /afs/usatlas.bnl.gov/doc/www/computing/cache and updated every night. The BNL cache is registered in the pacman database as am-BNL. It takes one hour or less to download the ATLAS software release from the local cache. The example commands for downloads:

pacman -get am-BNL:12.5.0

installs release 12.5.0

pacman -get am-BNL:Multi -allow trust-all-caches tar-overwrite

installs all available project oriented releases

The general instructions from the Distribution Kits support group provide more information about downloading procedures.

The manager of the BNL pacman cache is Shuwei Ye.
