Divisible load theory is a methodology involving the linear and continuous modeling of partitionable computation and communication loads for parallel processing. It adequately represents an important class of problems with applications in parallel and distributed system scheduling, various types of data processing, scientific and engineering computation,… (More)

Thomas G. Robertazzi State University of New York, Stony Brook T he increasing prevalence of multiprocessor systems and data-intensive computing has created a need for efficient scheduling of computing loads, especially parallel loads that are divisible among processors and links. During the past decade, divisible load theory has emerged as a powerful tool… (More)

This is a book intended for first-year graduate level courses in statistical performance evaluation. The book can be used for both network performance and computer system performance courses although the emphasis is on computer networks. It assumes a background in computer networks (first graduate course). Readers should have solid mathematics background if… (More)

The use of divisible load scheduling theory is proposed to model and design grid systems such as those arising in large physics experiments. Current divisible load theory is summarized. A typical application, the STAR experiment at RHIC is discussed. This includes a sample calculation based on existing infrastructure numbers.

The generation of transmission schedules for selforganizing radio networks by traffic sensitive algorithms is described. A centralized “Traffic” algorithm that can be used as a performance benchmark is presented. Also described is a distributed “degree” algorithm that is a traffic sensitized version of an algorithm developed by Ephremides and lhong . Two… (More)

A study of scalable data intensive scheduling involving load distribution on multi-level fat tree networks is presented. It is shown that the speedup of processing divisible loads concurrently on a homogeneous single level tree increases linearly as the number of processors is increased. This behavior is markedly different from that of past research on… (More)

A bus oriented network where there is a charge for the amount of divisible load processed on each processor is investigated. A cost optimal processor sequencing result is found which involves assigning load to processors in nondecreasing order of the cost per load characteristic of each processor. More generally, one can trade cost against solution time.… (More)

In recent years there has been an increasing interest in distributed intelligent sensor networks [ 1121. This interest has been generated by the requirements of military surveillance systems and other civilian applications. An intelligent sensor network is a collection of units with sensing, computational, and communication ability. Thus one has a network… (More)
