The ever-increasing presence of digital data and computers requires pushing for new levels of scalability and sustainability of computing systems in order to address the huge data and processing requirements of the near future. Ultrascale computing systems (UCSs) are a solution. Envisioned as large-scale complex systems joining parallel and distributed computing systems, which can be located at multiple sites and cooperate to provide the required resources and performance to the users, they could extend individual systems to provide the resources needed. UCSs are expected to be two to three orders of magnitude larger than today systems, including systems with unprecedented amounts of heterogeneous hardware, lines of source code, numbers of users, and volumes of data.
The book is composed of seven chapters covering aspects related to programming models, runtimes, resilience, data management, energy efficiency, and applications. Globally, the book shows that UCS development requires research and development of novel domain-specific, but interoperable tools to enable high productivity of human-computer interaction, leading toward robust solutions through multi-domain cooper-ative approaches using energy efficient hardware–software co-design principles.
Legion is a new framework for developing collaborative web applications that transparently leverage on the principles of edge computing by enabling direct browser-to-browser communication. Legion was implemented in javascript and it uses the Web Real-Time Communications to establish direct communication channels among web application users.
The Lasp language and programming system was designed for application development on unreliable distributed systems, and in particular for edge computing. Lasp allows developers to write applications by composing CRDTs, as explained above. In addition to composition, Lasp also provides a monotonic conditional operation that allows executing application logic based on monotonic conditions on CRDTs. The Lasp implementation combines a programming layer based on synchronization-free computing with a communication layer based on hybrid gossip. This makes the implementation highly resilient and well adapted to edge networks.
The book is oriented toward those professionals and researchers interested in the large-scale parallel and distributed systems area, especially to those interested in the software stack. It could be used as an introduction to the area, as it covers the most important areas, presenting applied research works. The book identifies and shows mid-term research challenges that are still to be solved. Thus, it could be used also by researchers starting their work in the area.
