Book Description
The performance of your local area network (LAN) can directly affect your company’s business success. In small and medium businesses alike, employees need quick, reliable access to applications and data to perform their jobs. A LAN that delivered adequate performance when installed, however, may now be straining. Factors contributing to the need for an upgrade are more users, more powerful PCs and servers, more demanding applications, and the growing role of the intranet.

Book Description
The Complete Guide to Optimizing Systems Performance Written by the winner of the 2013 LISA Award for Outstanding Achievement in System Administration Large-scale enterprise, cloud, and virtualized computing systems have introduced serious performance challenges. Now, internationally renowned performance expert Brendan Gregg has brought together proven methodologies, tools, and metrics for analyzing and tuning even the most complex environments. Systems Performance: Enterprise and the Cloud focuses on Linux(R) and Unix(R) performance, while illuminating performance issues that are relevant to all operating systems. You'll gain deep insight into how systems work and perform, and learn methodologies for analyzing and improving system and application performance. Gregg presents examples from bare-metal systems and virtualized cloud tenants running Linux-based Ubuntu(R), Fedora(R), CentOS, and the illumos-based Joyent(R) SmartOS(TM) and OmniTI OmniOS(R). He systematically covers modern systems performance, including the "traditional" analysis of CPUs, memory, disks, and networks, and new areas including cloud computing and dynamic tracing. This book also helps you identify and fix the "unknown unknowns" of complex performance: bottlenecks that emerge from elements and interactions you were not aware of. The text concludes with a detailed case study, showing how a real cloud customer issue was analyzed from start to finish. Coverage includes - Modern performance analysis and tuning: terminology, concepts, models, methods, and techniques - Dynamic tracing techniques and tools, including examples of DTrace, SystemTap, and perf - Kernel internals: uncovering what the OS is doing - Using system observability tools, interfaces, and frameworks - Understanding and monitoring application performance - Optimizing CPUs: processors, cores, hardware threads, caches, interconnects, and kernel scheduling - Memory optimization: virtual memory, paging, swapping, memory architectures, busses, address spaces, and allocators - File system I/O, including caching - Storage devices/controllers, disk I/O workloads, RAID, and kernel I/O - Network-related performance issues: protocols, sockets, interfaces, and physical connections - Performance implications of OS and hardware-based virtualization, and new issues encountered with cloud computing - Benchmarking: getting accurate results and avoiding common mistakes This guide is indispensable for anyone who operates enterprise or cloud environments: system, network, database, and web admins; developers; and other professionals. For students and others new to optimization, it also provides exercises reflecting Gregg's extensive instructional experience.

Book Description
"Performa 15 is the sixth volume in an acclaimed series on the Performa biennials that adds to the rich history of artists’ performance, presenting the most exciting innovations in live art across disciplines, including dance, film, sound, architecture, and poetry. Celebrating ten years since the founding of the Performa biennial in 2005, Performa 15 also reached back across centuries as part of its research: this edition took the Renaissance as its underlying “anchor,” showing the importance of performance by visual artists in the aristocratic courts as well as in the public pageantry of those earlier times.This beautiful book features documentation of commissions by the 65 artists from 12 countries who took part, such as Robin Rhode (South Africa), Pauline Curnier Jardin (France), Edgar Arceneaux (United States), Erika Vogt (United States), Jérôme Bel (France), and Francesco Vezzoli (Italy) in collaboration with principal classical ballet dancer David Hallberg (United States), among many others. Performa 15’s Pavilion Without Walls program presented a unique series of workshops, conversations, and performances with artists, curators, and writers from Australia.With a foreword by renowned curator and art historian Germano Celant, Performa 15 features in-depth interviews with artists and texts by art historians, curators, and critics, including Claire Bishop, Mark Beasley, Adrienne Edwards, and Jason Farago. Fully illustrated with performance photographs by Paula Court and other contributors, Performa 15 captures a critical juncture in the evolution of performance within the visual arts and the world’s leading performance biennial."--

Book Description
The 5th International Symposium on High Performance Computing (ISHPC–V) was held in Odaiba, Tokyo, Japan, October 20–22, 2003. The symposium was thoughtfully planned, organized, and supported by the ISHPC Organizing C- mittee and its collaborating organizations. The ISHPC-V program included two keynote speeches, several invited talks, two panel discussions, and technical sessions covering theoretical and applied research topics in high–performance computing and representing both academia and industry. One of the regular sessions highlighted the research results of the ITBL project (IT–based research laboratory, http://www.itbl.riken.go.jp/). ITBL is a Japanese national project started in 2001 with the objective of re- izing a virtual joint research environment using information technology. ITBL aims to connect 100 supercomputers located in main Japanese scienti?c research laboratories via high–speed networks. A total of 58 technical contributions from 11 countries were submitted to ISHPC-V. Each paper received at least three peer reviews. After a thorough evaluation process, the program committee selected 14 regular (12-page) papers for presentation at the symposium. In addition, several other papers with fav- able reviews were recommended for a poster session presentation. They are also included in the proceedings as short (8-page) papers. Theprogramcommitteegaveadistinguishedpaperawardandabeststudent paper award to two of the regular papers. The distinguished paper award was given for “Code and Data Transformations for Improving Shared Cache P- formance on SMT Processors” by Dimitrios S. Nikolopoulos. The best student paper award was given for “Improving Memory Latency Aware Fetch Policies for SMT Processors” by Francisco J. Cazorla.

Book Description
Transactions on HiPEAC aims at the timely dissemination of research contributions in computer architecture and compilation methods for high-performance embedded computer systems. Recognizing the convergence of embedded and general-purpose computer systems, this journal publishes original research on systems targeted at specific computing tasks as well as systems with broad application bases. The scope of the journal therefore covers all aspects of computer architecture, code generation and compiler optimization methods of interest to researchers and practitioners designing future embedded systems. This third issue contains 14 papers carefully reviewed and selected out of numerous submissions and is divided into four sections. The first section contains the top four papers from the Third International Conference on High-Performance Embedded Architectures and Compilers, HiPEAC 2008, held in Göteborg, Sweden, in January 2008. The second section consists of four papers from the 8th MEDEA Workshop held in conjunction with PACT 2007 in Brasov, Romania, in September 2007. The third section contains two regular papers and the fourth section provides a snapshot from the First Workshop on Programmability Issues for Multicore Computers, MULTIPROG, held in conjunction with HiPEAC 2008.
