Data processing in high-performance computing systems

The paper integrates the results of a large group of authors working in different areas that are important in the scope of big data, including but not limited to: overview of the basic solutions for the development of data centers; storage and processing; decomposition of a problem into sub-problems of lower complexity (such as applying divide and conquer algorithms); models and methods allowing broad parallelism to be realized; alternative techniques for potential acceleration; programming languages; and practical applications

When Claims of Understanding Are Less Than Affiliative

Conversation analysis has established that the smooth progression of interaction and the accomplishment of action rest on joint understanding, which is implicitly built by a next turn of talk. In this article we examine explicit claims to intersubjective understanding from a range of settings from the institutional to the mundane. Our target expressions have the general form; I + understand + YOU + PSYCHOLOGICAL FORMULATION such as I understand your concern and I see that this is frustrating you. We propose these expressions do pro forma affiliationthat is, they make a show of affiliating, even if in fact there is no affiliation. By explicitly claiming and demonstrating an understanding of the other speakers subjectivity, our target expression orients to misalignment between the parties, makes a show of other-attentiveness and bridges a shift that advances a speakers interactional agenda. Our contribution is to show the strategic function of a previously undocumented pro-social grammatical-conversational structure. Data are in English, and in Estonian and Swedish with English translation

BALTEX-an interdisciplinary research network for the Baltic Sea region

BALTEX is an environmental research network dealing with the Earth system of the entire Baltic Sea drainage basin. Important elements include the water and energy cycle, climate variability and change, water management and extreme events, and related impacts on biogeochemical cycles. BALTEX was founded in 1993 as a GEWEX continental-scale experiment and is currently in its second 10 yr phase. Phase I (1993-2002) was primarily dedicated to hydrological, meteorological and oceanographic processes in the Baltic Sea drainage basin, hence mostly dealt with the physical aspects of the system. Scientific focus was on the hydrological cycle and the exchange of energy between the atmosphere, the Baltic Sea and the surface of its catchment. The BALTEX study area was hydrologically defined as the Baltic Sea drainage basin. The second 10 yr phase of BALTEX (Phase II: 2003-12) has strengthened regional climate research, water management issues, biogeochemical cycles and overarching efforts to reach out to stakeholders and decision makers, as well as to foster communication and education. Achievements of BALTEX Phase II have been the establishment of an assessment report of regional climate change and its impacts on the Baltic Sea basin (from hydrological to biological and socio-economic), the further development of regional physical climate models and the integration of biogeochemical and ecosystem models. BALTEX features a strong infrastructure, with an international secretariat and a publication series, and organizes various workshops and conferences. This article gives an overview of the BALTEX programme, with an emphasis on Phase II, with some examples from BALTEX-related research
