This paper advocates a configurable approach to software for satellite graphics in which of the division labor between the host and satellite computers can be easily changed after an application program has been written. A software system, CAGES (Configurable applications for Graphics Employing Satellites), im- plements this approach. CAGES can substantially simplify the application programmer's task of programming a host and satellite computer by making the intercomputer interface relatively invisible to him, while at the same time allowing him the efficiency and flexibility that can result from direct application program- ming of the satellite computer. Proper design of configurable programs is facilitated by a mathematical model defining a pairwise meas- ure of program module inter-dependence. Experience with this model has resulted in a set of programming guidelines that further aid the application programmer in producing a suitable program structure.
In this study we construct a simulator of a data base management system running in a virtual memory environment. We use the simulator to investigate the value of using an I/O buffer in this environment. The simulator ...

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 integra...
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.
