Holistic Approach to management of it infrastructure for environmental monitoring and decision support systems with urgent computing capabilities
Future Generation Computer Systems, 2018Co-Authors: Bartosz Balis, Robert Brzozawoch, Marian Bubak, Marek Kasztelnik, Bartosz Kwolek, Piotr Nawrocki, Piotr Nowakowski, Tomasz Szydlo, Krzysztof ZielinskiAbstract:Abstract Modern environmental monitoring and decision support systems are based on complex IT infrastructures comprising multiple hardware and software subsystems that need to provide a variety of Quality of Service (QoS) guarantees required for urgent computing services, essential in emergency situations. Such IT infrastructures need to be managed in order to maintain the quality of service, which–especially when operating in the urgent mode–involves optimization of multiple, often conflicting, objectives and making trade-offs between them. Existing Approaches do not solve this issue optimally because they focus on delivering quality of service within individual subsystems in isolation. We propose a Holistic Approach to system management which takes into account knowledge about the system as a whole—in particular the interplay of conflicting objectives and configuration options across all subsystems. We argue that such an Approach produces a better configuration of the involved subsystems, improving the resolution of trade-offs between cost, energy and performance objectives, leading to their better overall fulfillment in comparison with the non-Holistic Approach in which individual subsystems are managed in isolation. We validate our Approach using a prototype implementation of the Holistic optimization algorithm—the Holistic Computing Controller, and applying it to a smart levee monitoring and flood decision support system.

a Holistic Approach to marine eco systems biology
PLOS Biology, 2011Co-Authors: Eric Karsenti, Colomban De Vargas, Silvia G Acinas, Peer Bork, Chris Bowler, Jeroen Raes, Matthew B Sullivan, Detlev ArendtAbstract:With biology becoming quantitative, systems-level studies can now be performed at spatial scales ranging from molecules to ecosystems. Biological data generated consistently across scales can be integrated with physico-chemical contextual data for a truly Holistic Approach, with a profound impact on our understanding of life [1]–[5]. Marine ecosystems are crucial in the regulation of Earth's biogeochemical cycles and climate [6],[7]. Yet their organization, evolution, and dynamics remain poorly understood [8],[9]. The Tara Oceans project was launched in September 2009 for a 3-year study of the global ocean ecosystem aboard the ship Tara. A unique sampling programme encompassing optical and genomic methods to describe viruses, bacteria, archaea, protists, and metazoans in their physico-chemical environment has been implemented. Starting as a grassroots initiative of a few scientists, the project has grown into a global consortium of over 100 specialists from diverse disciplines, including oceanography, microbial ecology, genomics, molecular, cellular, and systems biology, taxonomy, bioinformatics, data management, and ecosystem modeling. This multidisciplinary community aims to generate systematic, open access datasets usable for probing the morphological and molecular makeup, diversity, evolution, ecology, and global impacts of plankton on the Earth system.
