PyGTK Techniques and Applications
"PyGTK Techniques and Applications" "PyGTK Techniques and Applications" is an authoritative and comprehensive guide designed for software developers and architects building advanced graphical user interfaces with PyGTK and Python. The book begins by demystifying the architecture of PyGTK, exploring its historical evolution and detailing its object model, signal mechanisms, and event-driven design. Readers are introduced to in-depth practices for memory management, type integration with Python, threading, and strategies for ensuring high performance and stability in contemporary GUI applications. Through a series of expertly structured chapters, the book advances from fundamental concepts to sophisticated development patterns. It delves into advanced widget programming, including the creation of custom controls, complex layouts, accessibility, and dynamic theming. A dedicated exploration of Model/View/Controller design patterns, graphics, multimedia integration, and robust application structuring equips readers to handle both routine and demanding user interface scenarios. Additional topics—such as native library interfacing, D-Bus communication, web integration, internationalization, and automated testing—provide a holistic approach to building modern, maintainable, and scalable applications. The final sections spotlight real-world case studies, demonstrating how PyGTK powers scientific, creative, and enterprise applications, as well as embedded and hybrid devices. Readers gain practical insights from analyses of open-source projects and innovative UI paradigms. With thorough coverage of packaging, deployment, error handling, and marketplace distribution, "PyGTK Techniques and Applications" is an essential resource for any developer looking to master cross-platform GUI creation and deliver professional-grade Python software.

Applications, Tools and Techniques on the Road to Exascale Computing
Single processing units have now reached a point where further major improvements in their performance are restricted by their physical limitations. This is causing a slowing down in advances at the same time as new scientific challenges are demanding exascale speed. This has meant that parallel processing has become key to High Performance Computing (HPC).This book contains the proceedings of the 14th biennial ParCo conference, ParCo2011, held in Ghent, Belgium. The ParCo conferences have traditionally concentrated on three main themes: Algorithms, Architectures and Applications. Nowadays though, the focus has shifted from traditional multiprocessor topologies to heterogeneous and manycores, incorporating standard CPUs, GPUs (Graphics Processing Units) and FPGAs (Field Programmable Gate Arrays). These platforms are, at a higher abstraction level, integrated in clusters, grids and clouds. The papers presented here reflect this change of focus. New architectures, programming tools and techniques are also explored, and the need for exascale hardware and software was also discussed in the industrial session of the conference.This book will be of interest to all those interested in parallel computing today, and progress towards the exascale computing of tomorrow.
