Apr 1, 2026April 2026: Delivered a stable, memory-aware CI/CD pipeline for Neurodamus and released version 4.2.1 with enhanced neuron model support, along with memory-aware dry-run and load-balancing workflows. Implemented OpenMPI-based memory measurement in integration CI, added a memory-tracker option, and introduced a CLI-driven dry-run mode that improves memory estimation and distribution across ranks. This work improves release reliability, resource utilization, and model capabilities (Allen's V1 point neuron).
