The purpose of this paper is to investigate the solution of the fourth order boundary value problem μz= — α(s)μsssswith boundary conditions μs(0) = μs(a) — μsss(0) = μsss(a) = 0, where α(s) is square integrable on 0 0, and 0 < z < ∞. This problem arises in certain areas of fluid dynamics. If [0, a] is divided into equal intervals of length h such that 0 — s1 < s2 <… < sn-1

A trace-driven model is used to study the effects of various schedulers and deadlock control algorithms, and their interactions, on response times in a general-purpose operating system. Jobs' requests for memory and processors are extracted from a production load and used to drive a detailed simulation program. The simulation results show that response time is more sensitive than CPU utilization to differences between schedulers and deadlock control algorithms. Preemptive scheduling improves response time but degrades CPU utilization. Preemptive deadlock control algorithms improve both measures of performance. There are significant interactions between schedulers and deadlock control algorithms. Deadlock control algorithms can not be expected to optimize resource utilization. 1974 ACM. All rights reserved.

presents an in-depth analysis of several commonly observed regular and irregular computations for multiprocessor systems. This book includes techniques which enable researchers and application developers to quantitatively determine the effects of algorithm data dependencies on execution time, on communication requirements, on processor utilization and on the speedups possible.;Starting with simple, two-dimensional, diamond-shaped directed acyclic graphs, the analysis is extended to more complex and higher dimensional directed acyclic graphs. The analysis allows for the quantification of the computation and communication costs and their interdependencies. The practical significance of these results on the performance of various data distribution schemes is clearly explained. Using these results, the performance of the parallel computations are formulated in an architecture independent fashion. These formulations allow for the parameterization of the architecture specitific entities such as the computation and communication rates. This type of parameterized performance analysis can be used at compile time or at run-time so as to achieve the most optimal distribution of the computations.;The material in;connects theory with practice, so that the inherent performance limitations in many computations can be understood, and practical methods can be devised that would assist in the development of software for scalable high performance systems.
