Abstract

NBI-Slurm is a Perl package that provides a simplified, user-friendly interface for submitting and managing jobs on SLURM high-performance computing (HPC) clusters. It offers both a library of Perl modules for programmatic job management and a suite of command-line tools designed to reduce the cognitive overhead of SLURM's native interface. Distinctive features of NBI-Slurm are (a) TUI applications to view and cancel jobs, (b) the possibility to generate tool-specific wrappers for (bioinformatic) tools and (c) an energy-aware scheduling mode -- "eco mode" -- that automatically defers flexible jobs to off-peak periods, helping research institutions reduce their computational carbon footprint without requiring users to manually plan submission times.
