From internet architecture research to standards

Many Internet architectural research initiatives have been undertaken over last twenty years. None of them actually reached their intended goal: the evolution of the Internet architecture is still driven by its protocols not by genuine architectural evolutions. As this approach becomes the main limiting factor of Internet growth and application deployment, this paper proposes an alternative research path starting from the root causes (the progressive depletion of the design principles of the Internet) and motivates the need for a common architectural foundation. For this purpose, it proposes a practical methodology to incubate architectural research results as part of the standardization process

A new approach in Business Process Management

The new wave of BPM (Business Process Management) is not Business Process Reenginering, enterprise application integration, workflow management or another packaged application – it's the synthesis and extension of all these technologies and techniques into a unified whole. This unified whole becomes a new foundation upon which the enterprise is built, an enterprise more in tune with the true nature of business processes and their management. In a competitive economy, where margins continue to narrow and the pressure to respond to market shifts is greater than ever, the business rules approach is a great paradigm shift toward the process-managed enterprise and a significant enabler for reinventing ERP and the whole enterprise applications system.integration, business rules (BR), Business Process Management (BPM), Enterprise Resource Planning (ERP), information technology (IT)

Janus II: a new generation application-driven computer for spin-system simulations

This paper describes the architecture, the development and the implementation of Janus II, a new generation application-driven number cruncher optimized for Monte Carlo simulations of spin systems (mainly spin glasses). This domain of computational physics is a recognized grand challenge of high-performance computing: the resources necessary to study in detail theoretical models that can make contact with experimental data are by far beyond those available using commodity computer systems. On the other hand, several specific features of the associated algorithms suggest that unconventional computer architectures, which can be implemented with available electronics technologies, may lead to order of magnitude increases in performance, reducing to acceptable values on human scales the time needed to carry out simulation campaigns that would take centuries on commercially available machines. Janus II is one such machine, recently developed and commissioned, that builds upon and improves on the successful JANUS machine, which has been used for physics since 2008 and is still in operation today. This paper describes in detail the motivations behind the project, the computational requirements, the architecture and the implementation of this new machine and compares its expected performances with those of currently available commercial systems.Comment: 28 pages, 6 figure
