The paper describes the parallel implementation ofudcomposite Newton-Cotes rules (Trapezoidal andudSimpson’s ⅓ rules) under PVM-based environment forudapproximating one-dimensional definite integral onudparallel and distributed computing systems.Theudparallelism is realized by master-slave relationship where the master process decomposes the interval of integration into n subintervals, then distribute to the slave processes.Thereby initiating work pool technique to ensure perfect workload balanced state to avoid unnecessary communication overheads among the various contending processors.The effectiveness of the approach used in connection with the novel workload management scheme is demonstrated in the good quality results and the global load optimization for the tested applied applicationudproblem.
