Energy challenges for ICT

The energy consumption from the expanding use of information and communications technology (ICT) is unsustainable with present drivers, and it will impact heavily on the future climate change. However, ICT devices have the potential to contribute signi - cantly to the reduction of CO2 emission and enhance resource e ciency in other sectors, e.g., transportation (through intelligent transportation and advanced driver assistance systems and self-driving vehicles), heating (through smart building control), and manu- facturing (through digital automation based on smart autonomous sensors). To address the energy sustainability of ICT and capture the full potential of ICT in resource e - ciency, a multidisciplinary ICT-energy community needs to be brought together cover- ing devices, microarchitectures, ultra large-scale integration (ULSI), high-performance computing (HPC), energy harvesting, energy storage, system design, embedded sys- tems, e cient electronics, static analysis, and computation. In this chapter, we introduce challenges and opportunities in this emerging eld and a common framework to strive towards energy-sustainable ICT

The future of computing beyond Moore's Law.

Moore's Law is a techno-economic model that has enabled the information technology industry to double the performance and functionality of digital electronics roughly every 2 years within a fixed cost, power and area. Advances in silicon lithography have enabled this exponential miniaturization of electronics, but, as transistors reach atomic scale and fabrication costs continue to rise, the classical technological driver that has underpinned Moore's Law for 50 years is failing and is anticipated to flatten by 2025. This article provides an updated view of what a post-exascale system will look like and the challenges ahead, based on our most recent understanding of technology roadmaps. It also discusses the tapering of historical improvements, and how it affects options available to continue scaling of successors to the first exascale machine. Lastly, this article covers the many different opportunities and strategies available to continue computing performance improvements in the absence of historical technology drivers. This article is part of a discussion meeting issue 'Numerical algorithms for high-performance computational science'

ERP customization failure: Institutionalized accounting practices, power relations and market forces

Purpose: This paper examines a detailed case study of Enterprise Resource Planning (ERP) customization failure in an Egyptian state-owned company (AML) by drawing on new institutional sociology and its extensions. It explains how ERP customization failure is shaped by the interplay between institutionalised accounting practices, conflicting institutions, power relations and market forces. Methodology/Approach: The research methodology is based on using an intensive case study informed by new institutional sociology, especially the interplay between conflicting institutions, power relations and market forces. Data were collected from multiple sources, including interviews, observations, discussions and documentary analysis. Findings: The findings revealed that the inability of the ERP system to meet the core accounting requirements of the control authorities (the Central Agency for Accountability) was the explicit reason cited for the ERP failure. The externally imposed requirements of the Uniform Accounting System and planning budgets were used to resist both other institutional pressures (from the Holding Company for Engineering Industries) and market and competitive pressures. Research limitations: There are some limitations associated with the use of the case study method, including the inability to generalize from the findings of a single case study, some selectivity in the individuals interviewed, and the subjective interpretation by the researchers of the empirical data. Practical implications: The paper identifies that the interplay between institutional pressures, institutionalised accounting practices, intra-organizational power relations, and market forces contributed to the failure to embed ERP in a major company. Understanding such relationships can help other organisations to become more aware of the factors affecting successful implementation of new ERP systems and provide a better basis for planning the introduction of new technologies. Originality/value of paper: This paper draws on recent research and thinking in sociology, especially the development and application of new institutional sociology. In addition, the paper is concerned with ERP implementation and use and management accounting in a transitional economy, Egypt, and hence contributes to debate about exporting Western accounting practices and other technologies to countries with different cultures and different stages of economic and political development.
