Perl-packages-CPAN

License information

This is a bundle of hundreds of packages, too much to search for and list all individual packages.

User documentation

From LUMI/24.03 onwards, this module is the new home for many Perl packages that we used to provide in the Perl module.

This is done to speed up the development and installation of a new central software stack after a system update, as Perl is in the critical path and having to build a full configuration slows down the development and deployment tremenduously.

Technical documentation

This is a bundle of packages taken from CPAN and largely based on the EasyBuild PErl-bundle-CPAN module.

Even with the GNU compilers, we experience problems that may be unique to SUSE or COS (Cray Operating System, a restricted SUSE). This situation only becomes worse when using other compilers, as many of those packages are not well maintained or tested on only a very limited range of OS variants and compilers. Moreover, Perl packages tend to be very small but with lots of dependencies, and CPAN is organised in a way that it is hard to do reproducible installations which is needed for a central software stack. The packages were split off from the regular Perl module as they slow down the development of the software stack too much.

Given that a Perl installation typically consists of hundreds of packages with small files, it is one of those things that should better be done into a container, especially when Perl is called inside a parallel process.

Getting this module into a new software stack does not have a high priority for LUST and it may be removed entirely in the future.
