A) Time to compute the reduced system, and B) maximum absolute error between the quasi-active and reduced system output using IRKA on cell n408. Solid lines correspond to the N = 41364 case, while dashed lines are for the N = 165330 case. In (A) the sudden drop in computation time around k = 10 occurs for both cases because at that point, though the shifts have not converged, the reduced system is accurate to a tolerance of 3 digits or more
