A distributed network consists of multiple autonomous computers that communicate through a communication media. In distributed network in which a task is divided into many fractions and each of which is to be get processed. The task allocation problem can be explained in terms of number of tasks and number of processors available. According to the task allocation problem if the number of task a...

In this paper, we address the problem of optimal distribution of computational tasks on a network of heterogeneous computers when one or more tasks do not fit into the main memory of the processors and when relative speeds vary with the problem size. We propose a functional performance model of heterogeneous processors that integrates many essential features of a network of heterogeneous comput...

Reverse logistics networks often consist of several tiers with independent members competing at each tier. This paper develops a methodology to examine the individual entity behavior in reverse production systems where every entity acts to maximize its own benefits. We consider two tiers in the network, collectors and processors. The collectors determine individual flow functions that relate th...

The interconnection network is the switching fabric responsible for providing communication between all processors in a parallel computer. Much research has been directed towards developing superior interconnection networks, but there is no general agreement that this problem is solved. The speakers for this panel session were asked to address the following question: for a given range of number...

We treat the number of random bits as a computational resource in distributed computations. We give a concrete application of these ideas by characterizing the number of random bits necessary and suucient to elect a leader in an anonymous network of processors by a probabilistic algorithm with overwhelming probability. Our main result is a proof that a constant number of random bits is actually...

Concurrent programs are traditionally described in terms of processes, an abstraction that hides the identity of the processor doing the actual execution. This hiding allows processes to be implemented by time-multiplexing one or more identical processors, making the process abstraction well suited for concurrent programs--like operating systems and scientific codestha t will be executed on uni...

According to the increasing complexity of network application and internet traffic, network processor as a subset of embedded processors have to process more computation intensive tasks. By scaling down the feature size and emersion of chip multiprocessors (CMP) that are usually multi-thread processors, the performance requirements are somehow guaranteed. As multithread processors are the heir ...

Although the net processing power in the network is increasing steadily, it is heterogeneous. Hence the immense compute-power may be underutilized at certain points while it remains inadequate at others. This paper proposes an active network-based framework that views the entire network as a single-entity to effectively utilize the network resources. The single-entity model is enabled by establ...

We propose a computational device based on evolutionary rules and communication within a network, similar to that introduced in [4], called network of evolutionary processors. An NP-complete problem is solved by networks of evolutionary processors of linear size in linear time. Some furher directions of research are finally discussed. ∗Research supported by the Dirección General de Enseñanza Su...
