High Performance It Services

An in-depth overview of an emerging field that brings together high-performance computing, big data processing, and deep lLearning. Over the last decade, the exponential explosion of data known as big data has changed the way we understand and harness the power of data. The emerging field of high-performance big data computing, which brings together high-performance computing (HPC), big data processing, and deep learning, aims to meet the challenges posed by large-scale data processing. This book offers an in-depth overview of high-performance big data computing and the associated technical issues, approaches, and solutions. The book covers basic concepts and necessary background knowledge, including data processing frameworks, storage systems, and hardware capabilities; offers a detailed discussion of technical issues in accelerating big data computing in terms of computation, communication, memory and storage, codesign, workload characterization and benchmarking, and system deployment and management; and surveys benchmarks and workloads for evaluating big data middleware systems. It presents a detailed discussion of big data computing systems and applications with high-performance networking, computing, and storage technologies, including state-of-the-art designs for data processing and storage systems. Finally, the book considers some advanced research topics in high-performance big data computing, including designing high-performance deep learning over big data (DLoBD) stacks and HPC cloud technologies.

This book on performance fundamentals covers UNIX, OpenVMS, Linux, Windows, and MVS. Most of the theory and systems design principles can be applied to other operating systems, as can some of the benchmarks. The book equips professionals with the ability to assess performance characteristics in unfamiliar environments. It is suitable for practitioners, especially those whose responsibilities include performance management, tuning, and capacity planning.

A comprehensive guide to transforming boards and achieving best-practice governance in any organisation. When practising good governance, the board is the vital driver of organizational success, while fostering positive social impact and economic value creation. At all levels, executives around the world are faced with complexities rising from disruptive business models, new technologies, socio-economic changes, shifting political circumstances, and an array of other sources. High Performance Boards is the comprehensive manual for attaining best-in-class governance, offering pragmatic guidance on improving board quality, accountability, and performance. This authoritative volume identifies the four dimensions, or pillars, which are crucial for establishing and maintaining best-practice boards: the people involved, the information architecture, the structures and processes, and the group dynamics and culture of governance. This methodology can be applied to any board in the world, corporate or non-profit organization, regardless of size, sector, industry, or context. Readers are introduced to a fictitious senior board member – an amalgamation of board members from well-known organisations – and follow her as she successfully handles real-life challenges with effective governance.
