超标量处理器乱序提交机制的研究与设计

针对超标量处理器中长周期执行指令延迟退休及持续译码导致的重排序缓存（ROB）阻塞问题,提出一种指令乱序提交机制。通过设计容量可配置的多缓存指令提交结构,实现存储器操作指令和ALU类型指令的分类退休,根据超标量处理器架构及性能需求对目标缓存和存储缓存容量进行参数化配置降低流水线阻塞风险,同时利用指令目的寄存器编码提交模式加快指令提交速率。实验结果表明,该机制提高了单次指令提交数量,基于该机制的超标量处理器相比传统基于ROB顺序提交机制的超标量处理器在减少硬件开销的情况下平均IPC指数提升46%,相比基于值预测、乱序退休和组提交的超标量处理器平均IPC指数增益为19%,综合性能更优。     

Digital creativity and transdisciplinarity at postgraduate level: the design and implementation of a transdisciplinary masters programme and its implications for creative practice

This article investigates how transdisciplinary approaches to curriculum design on a taught masters programme in creative technologies enhance digital creativity in students. Drawing on the experience of developing and running the Masters in Creative Technologies (MA/MSc) at the Institute of Creative Technologies at De Montfort University, Leicester, we explore a number of areas relating to transdisciplinary teaching and learning in higher education, including: how digital technologies enable students to work in a transdisciplinary manner; how working creatively with technology enables transdisciplinary modes of working; and the ways in which transdisciplinarity, enabled by digital technologies, has affected the creative practice of learners. The article discusses how the programme has developed a climate for creativity, and outlines how the knowledge and skills gained during a creative technologies-related transdisciplinary programme meet the needs of a changing workplace.     

Visualization and Analysis‐Oriented Reconstruction of Material Interfaces

Reconstructing boundaries along material interfaces from volume fractions is a difficult problem, especially because the under‐resolved nature of the input data allows for many correct interpretations. Worse, algorithms widely accepted as appropriate for simulation are inappropriate for visualization. In this paper, we describe a new algorithm that is specifically intended for reconstructing material interfaces for visualization and analysis requirements. The algorithm performs well with respect to memory footprint and execution time, has desirable properties in various accuracy metrics, and also produces smooth surfaces with few artifacts, even when faced with more than two materials per cell.     

Prevalence and personality correlates of Facebook bullying among university undergraduates

The purpose of the present study was to examine the prevalence of cyber-bullying through Facebook in a sample of 226 Greek university undergraduates, and to explore whether big five personality characteristics, narcissism, as well as attitudes toward Facebook, technological knowledge and skills were predictive of such behavior. Participants completed a self-report questionnaire measuring the above constructs. Results indicated that almost one third of the sample reported Facebook bullying engagement at least once during the past month, with male students reporting more frequent involvement than females. Bullying through Facebook was predicted by low Agreeableness and more time spent on Facebook only for males, whereas for females none of the studied variables predicted engagement in Facebook bullying. Findings are discussed in terms of prevention and intervention strategies.
