Problem
A scattering study computes eight incident energies, each requiring a 30-minute simulation, feeding a single convergence-analysis step that reads all eight outputs and takes 5 minutes, which in turn feeds three figures, each taking 1 second to render. Represent this as a directed acyclic workflow graph with each simulation node pointing to the analysis node, and the analysis node pointing to each figure node.
((a)) Give the total time for a full rerun of the entire workflow from scratch, in seconds.
((b)) The input parameters of energy simulation number 3 are changed and nothing else. List which nodes must rerun, and give the total rerun time in seconds.
((c)) Only the caption text inside one figure's script is edited. Give the rerun time in seconds.
