PALMS update Marco Mambelli 18/9/2013

2 PALMS project OASIS provides the infrastructure to host the software in CVMFS but the users need more guidance to install the software (1) and to access it from the OSG resources (2) Programs, Applications and Libraries Management and Setup – Is a system to install and manage software in OASIS – Simplifies the packaging and installation of different versions for different platforms – Helps users to setup the correct and desired environment (applications and libraries)

3 PALMS Software manager features Help packaging application and deploying it on OASIS (or CVMFS) Allow installs, updates and removals of applications and libraries without disrupting running jobs Allow multiple versions for distinct platforms Allow multiple versions for the same platform Does not require root on the OASIS server Can manage and solve dependencies and conflicts Help adapting and installing native packages

4 PALMS User features Provide a single command to setup a software – Works no matter the shell (no separate setup.sh and setup.csh) – PALMS selects the correct software version for the platform (OS and Architecture) – PALMS provides a default software version – Allows overrides (of the platform or the software versions) PALMS adds no performance penalty compared to plain OASIS Obviously access to OASIS is assumed
