In order to support parallel programming, almost all of the programming languages incorporate a high-level parallel computing model into the language by providing parallelism and synchronization mechanisms, such as Ada's task with rendezvous and Java's thread with synchronized method. Obviously, such a programming language can only support one high-level parallel computing model. Although the approach of one model is simple and fairly effective to some applications, unfortunately the problems in the real world are always too diverse to be solved by using a single parallel computing model. In this paper, a new object-oriented approach to this problem is proposed. After analyzing the high-level parallel models of the various languages, some novel object-oriented language mechanisms are presented. Based on them, the concept of object-oriented parallel framework is proposed and the method for expressing and using the high-level parallel computing models by parallel frameworks is discussed. As a result, the high-level computing models are separated from languages in some sense and more than one framework could be given within a single language. Therefore, using a single language to support the various parallel models turns to be feasible.
