First,this paper describes the rssearch backgroundand developing status of MPI. Then on this basis it will study and analyze the functions and features of MPI ,summa-rize its insufficiencies and gives some suggestions for modification.展开更多

It will become the foundation of mod-ern information society because of the excellent management efficiency, reliability, availability, expansibility and lowcost. In this paper, we discuss the key technology of DPNDS which includes data distributing, parallel data process-ing, data network storage, object-oriented data storage and then give some suggestions about the new research direc-tion.展开更多

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.展开更多
