39 GUSS: Gather-Update-Solve-Scatter • 100 scenarios, 38 iterations: (100+1)*38 = 3838 models Setting Solve time (secs) Solvelink=0 (default) 294.36 Solvelink=%Solvelink.CallModule% 239.57 Solvelink=%Solvelink.LoadLibrary% 16.21 GUSS 9.18 • Updates model data instead <strong>of</strong> matrix coefficients/rhs • Hot start (keeps the model hot inside the solver and uses solver’s best update mechanism) • Saves model generation and solver setup time • A priori knowledge <strong>of</strong> all scenario data
