An architecture for a tightly coupled conferencing system
Proceedings Third International Workshop on Object-Oriented Real-Time Dependable Systems, 2002Describes an architecture for a tightly coupled conferencing system on an asynchronous transfer mode (ATM) network. In order to provide multicast service, we construct a multicast environment using a multicast address resolution server (MARS) and multicast servers (MCSs).

Multitoroidal Interconnects For Tightly Coupled Supercomputers
IEEE Transactions on Parallel and Distributed Systems, 2008The processing elements of many modern tightly coupled multicomputers are connected via mesh or toroidal networks. Such interconnects are simple and highly scalable, but suffer from high fragmentation, low utilization, and insufficient fault tolerance when the resources allocated to each job are dedicated.

A Validation Technique for Tightly Coupled Protocols
IEEE Transactions on Computers, 1982For several years the authors have been part of an effort developing automated techniques for examining the syntax of protocols for the absence of various errors. Recently, we have turned our attention to trying to prove various functional properties of protocols used in ring-topology systems.

Tightly coupled views for navigating content repositories
Companion Proceedings of the XIV Brazilian Symposium on Multimedia and the Web, 2008The advantages and positive effects of tightly coupled interface components on search performance have been documented in several studies. This paper focuses on the implementation of tightly coupled views within the Media Watch on Climate Change, an interactive Web portal (www.ecoresearch.net/climate) combining a portfolio of semantic services with a ...

Prototyping and Programming Tightly Coupled Accelerators
2010A tightly coupled accelerator is specialized hardware attached to and controlled by a host processor. In this paper, we will discuss the features of tightly coupled accelerators and describe our programming model. We will show that our approach allows for the rapid prototyping and development of tightly coupled accelerators, using a worked out example ...

Events And Interrupts in Tightly Coupled Multiprocessors
IEEE Micro, 1985In a decentralized multiprocessor, events must be stored, queued, and acknowledged. This can be accomplished by implementing a special event receiver called a synapse and by utilizing several forms of acknowledge.

Photonic Tightly Coupled Array
IEEE Transactions on Microwave Theory and Techniques, 2018We present the first demonstration of a tightly coupled array (TCA) excited by high-power photodiodes directly integrated onto the antenna substrate. As a complex electrical feed network is not required to feed the radiating elements, the design can realize ultra-wide bandwidth while improving upon the size, weight, and power of conventional electronic-

directCell: Hybrid systems with tightly coupled accelerators
IBM Journal of Research and Development, 2009The Cell Broadband Engine® (Cell/B.E.) processor is a hybrid IBM PowerPC® processor. In blade servers and PCI Express® card systems, it has been used primarily in a server context, with Linux® as the operating system. Because neither Linux as an operating system nor a PowerPC processor-based architecture is the preferred choice for all applications ...

Modeling Architectural Support for Tightly-Coupled Accelerators
2020 IEEE International Symposium on Performance Analysis of Systems and Software (ISPASS), 2020As proposed accelerators target finer-grained chunks of computation and data movement, it becomes increasingly important to couple them tightly with the processor, avoiding long invocation delays. However, the large implementation design space of these Tightly-Coupled Accelerators (TCAs) makes it difficult to balance trade-offs between hardware ...
