If parallel computer systems are to achieve the kinds of productivity improvements necessary to meet the needs of high productivity computing systems (HPCS), then a radical change will be required in how tools are developed for programmers and users of these systems. The number and complexity of tools is making it difficult for developers to access and use the tools effectively, and the lack of...

One key to improving high-performance computing (HPC) productivity is finding 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. ...

OBJECTIVE To assess productivity costs incurred by rheumatoid arthritis, comprising paid as well as household productivity costs, from a societal perspective, using different methods. METHODS A questionnaire on productivity, including items of the Health and Labour Questionnaire, was completed by 576 patients with rheumatoid arthritis (mean disease duration seven years). The friction cost (FC...

In a series of talks at the recent Intel Developers Forum, the company tantalized industry watchers by dribbling out a few more details about its IA-64 instruction set and its first implementation, Merced. In a joint presentation by Intel’s John Crawford and Hewlett-Packard’s Jerry Huck, the two architects shed additional light on the IA-64 design. They provided further details on the architect...

HPCC (high performance computing challenge) benchmark is issued by DARPA HPCS (high productivity computing system) project which is meant to define the program performance boundaries, and it has received broad attention from both industry and academy. But actually, HPCC is not very popular now, which mostly can be attributed to its multiple performance parameters. Because of lacking of a unique...

In a database cluster, preventive replication can provide strong consistency without the limitations of synchronous replication. However, the original proposal [11] and its extension to partial replication [3] have performance limitations: to prevent conflicts, transactions are forced to wait a delay time before executing. In this paper, we address this problem in order to scale up to large clu...

In Bartling, Fehr and Schmidt (2012) we show theoretically and experimentally that it is optimal to grant discretion to workers if (i) discretion increases productivity, (ii) workers can be screened by past performance, (iii) some workers reciprocate high wages with high effort and (iv) employers pay high wages leaving rents to their workers. In this paper we show experimentally that the produc...

The relationship between productivity and biodiversity has long been an important issue in ecological research. However, in recent decades, most ecologists have primarily focused on species diversity while paying little attention to functional diversity and phylogenetic diversity (PD), especially in alpine meadow communities following fertilization. In this study, a fertilization experiment inv...
