Exploratory research contributes to the continued vitality of every discipline. The aim of exploratory research is to identify new tasks-tasks that cannot be solved by existing methods. Once a new task has been found, exploratory research seeks to develop a precise definition of the task and to understand the factors...
In this paper we study the problem of scheduling parallel program tasks that are enclosed in a set of nested loops on parallel computers. We first introduce a representation of the tasks and their relations in a loop. The representation allows us to express loop-carried data dependences among tasks as...

Dataparallel C is a SIMD extension to the standard C programming language. It is derived from the original C* language developed by Thinking Machines Corporation.. We have nearly completed a third-generation Dataparallel C compiler, which transforms Dataparallel C programs into SPMD-style C code suitable for compilation and execution on NCUBE...
It often makes sense to write a program in the SIMD style, even if the program is to execute on a MIMD computer. Simulating physical events, in which all motion takes place simultaneously, is one area in which SIMD languages fit the applications particularly well. In this paper we present...
This is an exhibit prepared by the Oregon Department of Fish and Wildlife for the Oregon Fish and Wildlife Commission.

Most irrigation water in Oregon is of excellent quality. Occasionally a deep well yields water that is too salty for irrigation, or contains constituents that are detrimental to plants or soils. Water can be of poor quality for irrigation because of the amount of impurity (salt) it contains or the...
Models of stand growth and yield must include an estimate of mortality. For individual-tree/distance-independent growth-and-yield models. it is necessary (1) to predict the probability of death of individual trees and (2) to keep stand projections within reasonable biological limits (e.g., the maximum basal area that the stand can achieve). In...
