Sep 1, 2025During 2025-09, nf-core/configs delivered key configuration and pipeline improvements that enhance scalability, efficiency, and maintainability. The Eddie system resource and memory configuration overhaul expands memory/CPU ceilings, removes legacy helpers, and aligns memory calculations with updated UoE Research Services policies to enable larger tasks while enforcing per-pipeline memory caps. In parallel, the RNA-seq pipeline was optimized for resource efficiency and structural cleanup, reducing FASTQC memory usage and removing an obsolete RNA-seq config as part of pipeline restructuring. These changes reduce risk, improve resource predictability, and simplify ongoing maintenance while preparing the ground for future optimizations.

May 1, 2025In May 2025, delivered targeted improvements to Eddie HPC configuration within nf-core/configs, enhancing reliability and maintainability of high-performance job settings. Completed two key changes: (1) memory configuration enhancements for Eddie HPC cluster with GB-unit memory calculations, alignment with admin changes removing memory in bytes, correct memory per CPU slot, and proper SGE flag formatting; (2) Eddie.config linting and formatting cleanup to fix linting/whitespace issues and reduce formatting-related warnings. These efforts were supported by careful review of commit history and align with broader admin and CI standards.
