Greenroads: A Sustainability Performance Metric for Roadways

A Metric for Performance Portability

The term “performance portability” has been informally used in computing to refer to a variety of notions which generally include: 1) the ability to run one application across multiple hardware platforms; and 2) achieving some notional level of performance on these platforms. However, there has been a noticeable lack of consensus on the precise meaning of the term, and authors’ conclusions rega...

LBF: A Performance Metric for Program Reorganization

✵ This work was supported in part by NSF award ASC-9703212, DOE Grant DE-FG02-93ER25176, and NIST CRA award 70-NANB-5H0055. Abstract We introduce a new performance metric, called Load Balancing Factor (LBF), to assist programmers with evaluating different tuning alternatives. The LBF metric differs from traditional performance metrics since it is intended to measure the performance implications...

Classifying Scientific Performance on a Metric-by-Metric Basis

In this paper, we outline a system for evaluating the performance of scientific research across a number of outcome metrics (e.g. publications, sales, new hires). Our system is designed to classify research performance into a number of metrics, evaluate each metric’s performance using only data on other metrics, and to cast predictions of future performance by metric. This study shows how data ...
