Efficient data movement is essential for extreme-scale parallel visualization and analysis algorithms. In this research, we benchmark and optimize the performance of collective and point-to-point communication patterns for data-parallel visualization of scalar and vector data. Two such communication patterns are global reduction and local nearest-neighbor communication. We implement scalable al...

In this paper we introduce an architecture for online database services oriented towards consumers. We identify two types of costs| access cost and communication cost. We demonstrate that dynamic allocation of data can minimize these costs. We do so by presenting eecient algorithms based on dynamic allocation; these algorithms optimize access and communication costs for various cost models, acc...

We describe an integrated modeling framework for an interactive power network (IPN) consisting of a power network (PN) and a wireless communication network (WCN). The PN is modeled using a set of piecewise-linear (PWL) equations. The WCN is modeled using a Markov-chain based model that can capture the randomness of the communication channel. The impacts of the WCN are incorporated into the PN m...

Cognitive Radio (CR) can optimize system objects by dynamically assigning network resource and adjusting network operations in terms of network environments and conditions. So CR technology is very suitable for building emergency communication system to improve resource utilization ratio and enhancing dependability and availability of communication services apparently. In this paper, background...

In this paper, we investigate the communication characteristics of the Message Passing Interface (MPI) implementation of the NAS parallel benchmarks and study the effectiveness of compiled communication for MPI programs. Compiled communication is a technique that utilizes the compiler knowledge of both the application communication requirement and the underlying network architecture to signific...

Digitalization of marketing forms preconditions for personalization and individualization advertising promotion goods (works, services). Databases about consumer preferences market situation are at the disposal major international corporations, which makes it difficult advertisers admen. It is envisaged that development technologies Internet Things (IoT) 6G cellular communication should change ...

agents, in a multi agent system, communicate with each other through the process of exchanging messages which is called dialogue. multi agent organization is generally used to optimize agents’ communications. holonic organization demonstrates a self-similar recursive and hierarchical structure in which each holon may include some other holons. in a holonic system, lateral communication occurs b...

The subject of this research is linguistic (or: language) audit. The term is new and not being widely used so far. Linguistic audit, in particular, is offered as a service of linguistic-consulting agencies’ activities. Modern linguistic consulting, according to the author, is a form of stimulating theoretical and practical development of linguistic ecology, a new branch of applied linguistics, ...

Communication synthesis is an essential step in hardware/software co-synthesis: many embedded systems use automatic generation of interface for point to point communication or use external supports of communication as standard bus or micro network. In this paper, we address the problem of hardware – software interface design in codesign approach for real-time applications. We refer to the hardw...
