Notes:
Abstract Two classes of adaptive quadrature algorithms for use on the ILLIAC IV are described, one designed for high processor utilization, the other for high processing speed. The results of simulation tests comparing algorithms from these two classes are summarized and commented on. The results indicate that a more truly adaptive algorithm without consistently high processor utilization is faster than one designed specifically for high utilization. For a better algorithm, the speedup over sequential processing ranges from 1.1 to 46.9 (average = 15.5) for 14 examples; this is considerably less than the maximum possible speedup of 64 but is still substantial.
