.... to overcoming the design barrier involves mapping the domain analysis directly to a concurrent solution, where each object in the problem specification becomes a concurrent (or active) object in the design (and implementation) For example, the Actor model proposed by Hewitt and defined by Agha [AGHA90, AGHA89, AGHA87, AGHA87a, AGHA86] could be assumed, and a parallel programming environment, such as Regis, MAGE93] could provide a target environment. 61 Unfortunately, an approach such as this can result in excessive concurrency. Generally, as the number of tasks in a solution increases, the amount of overhead associated with ....

.... between concurrent objects [6] The problem with parallel computation is that a high degree of indeterminacy is introduced by the fact that different segments of a parallel computation can be distributed throughout space and are executed at indeterminate points in time relative to one another [3]. These issues are transparent in a sequential execution. One consequence is that partially evaluated sections of programme coexist which greatly complicates the location and synchronisation of these sections and increases the risk of harmful interference between them. Parallel programming thus ....

....power and clean semantics. Since a functional language has no notion of state, it makes it easy to write parallel programs without races. The second is the limitation of functional programming languages. In spite of the above merits, there is a critical problem that functions do not have a history[9]. Programs written in functional language is suitable for applications such as scientific computation where side effects are undesirable and avoidable, not for applications such as database applications. So, we need to widen the application of multithreaded computations. The third is that ....
