Optimal replication of series-parallel graphs for computation- intensive applications by Sheng-Tzong Cheng( Book )

2 editions published between 1993 and 1994 in English and held by 7 WorldCat member libraries worldwide

Abstract: "We consider the replication problem of series-parallel (SP) task graphs where each task may run on more than one processor. The objective of the problem is to minimize the total cost of task execution and interprocessor communication. We call it, the minimum cost replication problem for SP graphs (MCRP-SP). In this paper, we adopt a new communication model where the purpose of replication is to reduce the total cost. The class of applications we consider is computation-intensive applications in which the execution cost of a task is greater than its communication cost. The complexity of MCRP-SP for such applications is proved to be NP-complete. We present a branch-and-bound method to find an optimal solution as well as an approximation approach for suboptimal solution. The numerical results show that such replication may lead to a lower cost than the optimal assignment problem (in which each task is assigned to only one processor) does. The proposed optimal solution has the complexity of O(n²2[superscript n]M), while the approximation solution has O(n⁴M²), where n is the number of processors in the system and M is the number of tasks in the graph."
Mission critical planning : AI on the MARUTI real-time operating system by James A Hendler( Book )

1 edition published in 1990 in English and held by 6 WorldCat member libraries worldwide

Critically important is the ability to correctly handle time dependent reasoning (directly modeled on the MARUTI operating system) and reaction, and to integrate such reaction with higher level plans for normal operation or error recovery."
A simple near-optimal solution to the drinking philosophers problem by D Ginat( Book )

3 editions published in 1989 in English and held by 6 WorldCat member libraries worldwide

Abstract: "We provide a solution to the drinking philosophers problem, defined by Chandy and Misra [1]. Our solution, unlike theirs, does not have a dining layer. By using bounded session numbers with occasional resets, we are able to reduce the message complexity per drinking session from the order of neighbors a philosopher has to the order of bottles he needs for drinking."

Modeling of cross traffic in conjunction with deterministic analysis of virtual circuits by Sheng-Tzong Cheng( Book )

1 edition published in 1992 in English and held by 5 WorldCat member libraries worldwide

Abstract: "The design and performance studies of computer networks have traditionally used stochastic models even though it is well recognized that there are strong deterministic dependences in the behavior of components of a network which are not reflected in such a model. Recently deterministic models have been formulated for a single virtual circuit and used for the design of flow control schemes. In this paper we extend the deterministic model to take into account the network topology and all the virtual circuits using the network. The basic model of a single server with several virtual circuits through it is introduced first. Next, the model for virtual circuits is formulated focusing primarily on the departure time of packets from various servers
Language support for Maruti real-time system by Vivek M Nirkhe( Book )

1 edition published in 1990 in English and held by 5 WorldCat member libraries worldwide

Abstract: "A time-driven approach in the design of hard real-time systems uses the time constraints of applications directly for their scheduling, to ensure that their deadlines are met. The time-driven approach requires the scheduler to know the resource requirements, time constraints, and execution time of each application. Communication, precedence and synchronization among processes affect the time constraints of applications, and must be taken into acount while scheduling. Since these constraints and requirements are application specific, they need to be derived from application programs. Therefore, the programming language has to provide the programmer with features to express them

Virtual circuits with cross traffic : model, analysis and parameter estimation by Bijendra N Jain( Book )

1 edition published in 1992 in English and held by 5 WorldCat member libraries worldwide

Abstract: "In this paper, we model the flow of packets between a given pair of source-destination hosts as a virtual circuit which passes through a tandem of network processors. Each network processor is assumed to concurrently process packets relating to other source-destination pairs of hosts (also termed cross traffic). As such, the model of the virtual circuit takes into account the net effect of all cross traffic that passes through the network processors. The model of a virtual cirtuit [sic] proposed in this paper has been analyzed to obtain inter-packet departure time as a function of inter-packet send time
The RPT parallel Gaussian elimination algorithm by Sam H Noh( Book )

A physical interchange of the values can be avoided by providing a permutation vector in a globally accessible location. We show experimental results that substantiate the use of logical pivoting."
Allocation of real-time computations under fault tolerance constraints by Shem-Tov Levi( Book )

2 editions published in 1988 in English and held by 5 WorldCat member libraries worldwide

Allocation of resources in next generation real time operating systems requires some important features in addition to those demonstrated by current systems, resulting in an increased complexity of each system. The allocation is closely related to the scheduling, and the two are based on time considerations, rather then on a static priority scheme. The allocation is fault tolerance motivated, to cope with the application's reliability goals. Distributed system issues and adaptive behavior requirements increase the complexity and significance of the allocation approach. The allocation scheme proposed here accomplishes the hard real time goal of guaranteeing a deadline satisfaction in case the job is accepted. In addition, this allocation scheme supports fault tolerance objectives in both damage containment and resiliency requirements. It does this in cooperation with a schedulability verification mechanism, and with an object architecture in which for each object there exists a calendar that maintains the time of its execution. A nice feature of this scheme is the way in which it can be used for reallocation while increasing the resiliency. Keywords: Real time, Resources management, Operating systems. (jhd)
DTP : an efficient transport protocol by Dheeraj Sanghi( Book )

1 edition published in 1991 in English and held by 5 WorldCat member libraries worldwide

Abstract: "We recently introduced a new flow control scheme [AgSa91], called send time control, which was designed based on a deterministic model of virtual circuits in a computer network. In this scheme, the time at which a packet is sent by a source is computed from estimates of round-trip time, traffic in the network and bottleneck service time. In this paper, we describe a new transport protocol, called DTP, which uses send time control as its flow control scheme. Preliminary measurements of coast-to-coast connections over the Internet show significant performance improvement over TCP which is the most commonly used transport protocol in the Internet today."
