The Common Object Request Broker Architecture (CORBA) is a main specification applied to the dis-tributed parallel program design at present. It includes many services, in which Event Service can provide the asyn-chronous communication model for the distributed parallel program design. This paper introduces the Event Service ofCORBA, then designs and implements a distributed parallel model based on Event Service. This model is made to im-plement overlap of the computing and communication , to reduce the unnecessary time for waiting and enhance theparallel effect. The paper also shows the practical application of the model with an example of the distributed parallelmatrix multiplication.
