The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We present astroCAMP, a reproducible benchmarking and co-design framework for SKA-scale imaging, contributing: (1) a unified metric suite spanning performance, utilisation, memory/data-movement, sustainability, economics, and scientific fidelity; (2) standardised SKA-representative datasets and benchmark configurations; (3) a multi-objective co-design formulation linking quality constraints to time-, energy-, carbon-, and cost-to-solution; and (4) a design-space exploration workflow to derive Pareto-optimal operating regions.

C2weakest assumption

That quantifiable fidelity thresholds acceptable to the SKA community can be defined and used as hard constraints in the multi-objective optimization without invalidating the scientific utility of the resulting images.

C3one line summary

astroCAMP supplies a unified metric suite, representative datasets, and multi-objective co-design workflow to optimize SKA radio imaging for time, energy, carbon, cost, and fidelity on heterogeneous hardware.
