One key to improving high performance computing (HPC) productivity is to find better ways to measure it. We define productivity in terms of mission goals, i.e. greater productivity means that more science is accomplished with less cost and effort. Traditional software productivity metrics and computing benchmarks have proven inadequate for assessing or predicting such end-to-end productivity. I...

Computational scientists face many challenges when developing software that runs on large-scale parallel machines. However, their software development processes have not previously been studied in much detail by software engineering researchers. To better understand the nature of software development in this context, we examined five largescale computational science software projects, known as ...

this paper is a survey of recent contributions to and developments in the relationship between efficiency and productivity via the production function. the objective is to provide a brief discussion on data and on the methods of measuring efficiency and productivity. first, we introduce the reader to the measurement of partial and total factor productivity in the context of static and firm - sp...

introduction: partnership working plays an important role in the health system, results in delivery of coordinated packages of services to patients, and reduces the impact of organizational fragmentation. method: the study aimed to determine the relationship between partnership working and productivity in the employees of a university of medical sciences in the south of iran. results: according...

Common belief and some empirical evidence indicates that productivity of a farmer may increase with age, reach some maximum level, and then decrease with further age (Tauer 1984; Tauer 1995). If productivity exhibits a life-cycle pattern, then productivity of agriculture may decrease as the U.S. farm population continues to age. Lifecycle changes are also critical in planning for succession of ...

: recently, productivity discussion has been considered in social and scientific discussions. in the extreme world of competition and growth of technology, policy makers and management consider increase of productivity as tool or as a goal occasionally (3) in this research it is intended to recognize effects factor on increase of productivity particularly factors such as providing essential nee...

The Malmquist productivity index evaluates the productivity change of a decision making unit (DMU) between two time periods. In this current study, a method is proposed to compute the Malmquist productivity index in several time periods (from the first to the last periods) in data envelopment analysis (DEA) and then, the obtained Malmquist productivity index is compared with Malmquist produ...

One of the major goals in ecology is to determine the mechanisms that drive the asymptotic increase in ecosystem productivity with plant species diversity. Niche complementarity, the current paradigm for the asymptotic diversity-productivity pattern, posits that the addition of species to a community increases productivity because each species specializes on different resources and thus can mor...

In some situations the producers desire to maximize total profit of Decision Making Units (DMUs) while the inputs and outputs prices of DMUs change from one time period to another. In this paper, the researchers develop productivity index when producers are going to maximize total profit when the price of inputs and outputs are known.The proposed method uses all price information about inputs a...
