Tempo: Robust and Self-Tuning Resource Management in Multi-tenant Parallel Databases

Publisher: name: arXiv
Year: 2015
Subjects: subject: Databases (cs.DB)
subject: FOS: Computer and information sciences

description: Multi-tenant database systems have a component called the Resource Manager, or RM that is responsible for allocating resources to tenants. RMs today do not provide direct support for performance objectives such as: "Average job response time of tenant A must be less than two minutes", or "No more than 5% of tenant B's jobs can miss the deadline of 1 hour." Thus, DBAs have to tinker with the RM's low-level configuration settings to meet such objectives. We propose a framework called Tempo that brings simplicity, self-tuning, and robustness to existing RMs. Tempo provides a simple interface for DBAs to specify performance objectives declaratively, and optimizes the RM configuration settings to meet these objectives. Tempo has a solid theoretical foundation which gives key robustness guarantees. We report experiments done on Tempo using production traces of data-processing workloads from companies such as Facebook and Cloudera. These experiments demonstrate significant improvements in meeting desired performance objectives over RM configuration settings specified by human experts.

description: This article discusses open scientific challenges for understanding development and evolution of speech forms, as a commentary to Moulin-Frier et al. (Moulin-Frier et al., 2015). Based on the analysis of mathematical models of the origins of speech forms, with a focus on their assumptions , we study the fundamental question of how speech can be formed out of non--speech, at both developmental and evolutionary scales. In particular, we emphasize the importance of embodied self-organization , as well as the role of mechanisms of motivation and active curiosity-driven exploration in speech formation. Finally , we discuss an evolutionary-developmental perspective of the origins of speech.
International Survey on Climate Change and Local Responses To It

description: The following results come from an International Survey on Climate Change And Local Responses To It, sent out earlier this year. I’ve collected the data from the responses and found a different outcome from what I was expecting. The survey was emailed to three different groups across two-hundred and thirty-three countries and territories. The first group was made up of four thousand climate change professionals who are both trained and working in the field. The second group was made up of one thousand members of the international financial investment community. The last group was made up of two hundred members of the hi-tech sub-communities: open source, software, Eco-hackers, DIY and members of the Maker movements. There were twenty questions in all, arranged into four groups: personal beliefs about climate and environmental changes, the state of local climate change monitoring and reporting systems, the need for local citizen involvement, and the types systems needed to monitor and report climate and environmental changes.

description: Mit den Bildungsstandards Mathematik ist der beschreibenden Statistik eine größere Rolle in der Schule zugekommen (Eichler & Vogel 2009, KMK 2003). Eng verbunden mit der Entwicklung von statistischem Denken ist der Begriff des Informal Inferential Reasoning (im Folgenden IIR; Makar, Bakker & Ben-Zvi 2011). Konstituierend für die Statistik ist hierbei nicht die reine Beschreibung von Daten, sondern die Fähigkeit, statistische Inferenzen zu ziehen. Dabei werden anhand von Daten allgemeine Aussage über die grundlegenden, unbekannten Phänomene getroffen, die diese Daten erzeugt haben (Makar & Rubin 2009). Lernprozesse zum IIR von Lernenden mit nur wenigen Vorerfahrungen werden dabei von der Forschung nur selten in den Blick genommen (Eichler & Vogel 2012). Der Verlauf solcher Lernprozesse (mit möglichen Zugänge für Lernende, vorunterrichtlichen Vorstellungen und intendierten Zielvorstellungen) muss weiter untersucht werden.

Habitat and distribution
Soil-dwelling species living in the litter of forest soils in the British Isles (Westwood 1842; Bagnall 1918b; Wygodzinsky 1941b; Carpenter 1988) and in the northwestern regions of continental Europe. It occurs in northern and central France from Brittany towards the Central massif (Condé & Bareth 1998) and reaches its easternmost extension in the Black Forest, Germany (Bockm̹hl 1956). The reference in Poland by Stach (1920, 1959) may be considered a misidentification.

description: Today‘s manufacturing industries are facing lot of threat and competition and problems in meeting challenges of changing market conditions. Inventory is the heart of any organizational body which needs lot of focus in planning of procurement if inventories from different suppliers and vendor and need very good storage conditions before they are issued to the production process. The level of inventory balance is necessary taking demand and supply of the finished goods in the market by big corporate and end users. The cost of inventory has significant effect in determining the cost price of the output. The cost of procurement, cost of holding, and storage cost are very much sensitive to each other in defining the success story of the industries. The experts in the field of cost accountancy have suggested various models of cost calculation so that the industries can continuously undertake the production process without nay fluctuations and variations.

description: En los últimos años, el consumo de nueces, en general, ha crecido y en particular la del marañón, debido a diversos factores, tales como, los cambios en los hábitos alimenticios y el desarrollo de los mercados saludables. En efecto, el estilo de vida agitado, la preferencia hacia comidas rápidas, la diversificación de la forma de consumo de las nueces, así como, el desarrollo de la industria de alimentos listo para comer y de alimentos saludables, ha provocado una tendencia al consumo de comidas rápidas y nutritivas. Las nueces producidas y exportadas por países en vías de desarrollo, no son productos finales para venta directa al consumidor, sino, que se trata de productos intermedios con mayor o menor grado de procesamiento (con o sin cáscara, tostadas), las cuales, pasan por diversos agentes encargados de la distribución o de la transformación y empaque. La demanda de productos procesados y empacados en los países de origen, es baja, en el caso del mercado europeo, existen empacadores con gran capacidad para abastecer directamente a los supermercados, realizar campañas publicitarias, manejar stock de productos de toda la gama de nueces y productos complementarios como las frutas secas y tener contratos de exclusividad.

description: The climate of Mars likely evolved from a warmer, wetter early state to the cold, arid current state. However, no solutions for this evolution have previously been found to satisfy the observed geological features and isotopic measurements of the atmosphere. Here we show that a family of solutions exist, invoking no missing reservoirs or loss processes. Escape of carbon via CO photodissociation and sputtering enriches heavy carbon (13C) in the Martian atmosphere, partially compensated by moderate carbonate precipitation. The current atmospheric 13C/12C and rock and soil carbonate measurements indicate an early atmosphere with a surface pressure <1 bar. Only scenarios with large amounts of carbonate formation in open lakes permit higher values up to 1.8 bar. The evolutionary scenarios are fully testable with data from the MAVEN mission and further studies of the isotopic composition of carbonate in the Martian rock record through time.

description: Guillain-Barré syndrome (GBS) is an acute autoimmune polyradiculoneuropathy that primarily affects theperipheral nervous system, leading to rapidly progressing muscle weakness and, in severe cases,respiratory failure and autonomic dysfunction. The exact etiology is not fully understood, but GBS isstrongly associated with preceding infections, particularly Campylobacter jejuni, Cytomegalovirus, andEpstein-Barr virus. Molecular mimicry is believed to play a significant role in the immune-mediatedattack on peripheral nerves. Diagnosis is based on clinical presentation, cerebrospinal fluid analysis, andelectrophysiological studies. The management of GBS involves supportive care, immunotherapy withintravenous immunoglobulin (IVIG) or plasma exchange, and rehabilitation. Although most patientsrecover, some experience long-term neurological deficits. This review provides a comprehensiveoverview of the epidemiology, etiology, pathogenesis, clinical presentation, diagnostic approaches,complications, and treatment strategies for GBS.
Extrinsische Rechtfertigung im Mathematikunterricht: Welche Axiomensysteme setzen sich durch?

description: „Schülern sollte bewusst gemacht werden, dass es Axiome in der Mathematik gibt, welche Rolle sie spielen und wie Mathematiker zu einer Einigung darüber gelangen, welche Axiome akzeptiert werden sollten.“ (Jahnke, Wambach 2013, S. 469, meine Übers.) Die in diesem Zitat zum Ausdruck gebrachte Haltung wird von mir in vollem Umfang geteilt. Sie bildet das Fundament der hier angestellten Überlegungen, die Teil meines Promotionsprojekts sind. Kernanliegen ist die Entwicklung zeitgemäßer Unterrichtsmaterialien zur axiomatischen Methode für die Sekundarstufe II. In Abschnitt 1 des vorliegenden Beitrags wird in kompakter Form dargestellt, welche Begriffe für eine Einführung in axiomatisches Denken und Arbeiten aus meiner Sicht mit Schülern erarbeitet werden sollten. Abschnitt 2 ist ein fachlicher und theoretischer Exkurs, der als Hintergrundwissen für den Leser gedacht ist und in dem die Bedeutung des Begriffs der Hypothese bzw. Forderung bei der Entwicklung und Bewertung mathematischer Theorien geschildert wird. Da dieser Aspekt im Themenbereich Zahlbereichserweiterungen besonders deutlich wird, skizziere ich in Abschnitt 3 ein Unterrichtskonzept für die Einführung der komplexen Zahlen, das den Fokus auf die Frage legt, warum sich diese anfangs auch als „absurd“ bezeichneten Zahlen letztendlich durchgesetzt haben.

Über eine Begriffsklärung und das Aufzeigen einer gesellschaftlichen Tendenz zu Großprojekten vor dem Hintergrund der Massenproduktion werden zunächst die Grundlagen der Arbeit hergeleitet sowie Charakteristika der vier beispielhaften Projekte untersucht und verglichen, was zu einer Typologie führt. Anschließend werden die vier Beispiele: linienförmiges Großprojekt - Neubaustrecke der Bundesbahn Hannover-Würzburg, flächenhaftes Großprojekt - Braunkohlentagebau in der Niederrheinischen Bucht, punktförmiges Großprojekt - Flughafen München II und netzförmiges Großprojekt - Netzwerk Oberitalien nach der entwickelten Methodik gegliedert sowie geschichtlich und strukturell differenziert vorgestellt. Abschließend werden anhand der Eingrenzung des Begriffs „Betroffenheit“ die Auswirkungen der vier Projekte heraus-gearbeitet, negative Folgen wie positive Effekte hergeleitet. Ihre zusammengefassten Betroffenheiten und die Facetten ihrer Auswirkungen ergeben schließlich auch eine abstrahierende räumlich-gesellschaftliche Einordnung von Großprojekten.

description: This paper proposes a study on inventory model for time linked holding cost and salvage value with probabilistic deterioration following various distributions. Shortage is assumed to be partially backlogged. Demand rate is time linked. Deterioration is a continuous random variable following some probabilistic distributions. We consider the uniform and triangular distributions. An expression for average total cost is derived as an Economic Order Quantity problem. Using the probabilistic distribution, the average total cost function is divided into two models - Model−I, and Model−II. To explain the solution procedure, two numerical examples are provided for both models. The convex property for the concerned average total cost functions is justified with the help of graphs in three dimensions. The optimal results are compared graphically for both the models.

description: This paper proposes an application of correlation-regression method to establish the statistical relationship between acceptance rate & first decision time of some indexed journals. We collect the data from two web sources: Elsevier journal finder, and Springer journal suggester. In this problem, we concentrate on the data of the acceptance rate and first decision time. To examine the relationship between these measures, we apply a statistical approach, which is based on correlation and regression analysis. We determine the relative error of the data collected. We plot the scatter diagram between the two measures. Correlation coefficient value is also calculated, that checks the significant connection between the two variables. The correlation analysis and regression analysis demonstrate that there is a moderate positive correlation between acceptance rate & first decision time.

description: A complete analysis of the essential spectrum of matrix-differential operators $\mathcal A$ of the form \begin{align} \begin{pmatrix} -\displaystyle{\frac{\rm d}{\rm d t}} p \displaystyle{\frac{\rm d}{\rm d t}} + q & -\displaystyle{\frac{\rm d}{\rm d t}} b^* \! + c^* \\[2mm] \hspace{6mm} b \displaystyle{\frac{\rm d}{\rm d t}} + c & \hspace{4mm} D \end{pmatrix} \quad \text{in } \ L^2((α, β)) \oplus \bigl(L^2((α, β))\bigr)^n \label{mo} \end{align} singular at $β\in\mathbb R\cup\{\infty\}$ is given; the coefficient functions $p$, $q$ are scalar real-valued with $p>0$, $b$, $c$ are vector-valued, and $D$ is Hermitian matrix-valued. The so-called "singular part of the essential spectrum" $σ_{\rm ess}^{\rm \,s}(\mathcal A)$ is investigated systematically. Our main results include an explicit description of $σ_{\rm ess}^{\rm \,s}(\mathcal A)$, criteria for its absence and presence; an analysis of its topological structure and of the essential spectral radius. Our key tools are: the asymptotics of the leading coefficient $π(\cdot,λ)=p-b^*(D-λ)^{-1}b$ of the first Schur complement of $\mathcal A$, a scalar differential operator but non-linear in $λ$; the Nevanlinna behaviour in $λ$ of certain limits $t\!\nearrow\!β$ of functions formed out of the coefficients in $\mathcal A$. The efficacy of our results is demonstrated by several applications; in particular, we prove a conjecture on the essential spectrum of some symmetric stellar equilibrium models.

Η αυξανόμενη χρήση αυτών των πηγών έχει οδηγήσει σε σοβαρές περιβαλλοντικές επιπτώσεις, με την κλιματική κρίση να είναι η σοβαρότερη σε παγκόσμιο επίπεδο. Η Ευρωπαϊκή Ένωση όπως και άλλοι φορείς έχουν αναλάβει πολυάριθμεςπρωτοβουλίες, και η Ευρώπη είναι αποφασισμένη με παραπάνω πρόβλημα είναι η αξιοποίηση των ανανεώσιμων πηγών ενέργειας (ΑΠΕ), οι οποίες είναι ανεξάντλητες και φιλικές ως προς το περιβάλλον. Η αξιοποίηση των ΑΠΕ έχει αυξηθεί δραματικά τα τελευταία χρόνια ενώ η χρήση τους γίνεται ακόμη και σε οικιακό επίπεδο.Συνεπώς, η παρούσα εργασία επικεντρώνεται στην τεχνοοικονομική μελέτη εγκατάστασης ενός υβριδικού οικιακού συστήματος στην περιοχή της Αττικής, στο νότιο προάστιο την επιβολή κανονισμών να μειώσει τη χρήση συμβατικών καυσίμων.Μία από τις λύσεις για το Άλιμος. Για την πραγματοποίηση της μελέτης χρησιμοποιήθηκε το λογισμικό HomerPro και αναλύθηκαν τέσσερις μελέτες περίπτωσης. Τα αποτελέσματα αναλύονται εκτενώς αποδεικνύοντας πως ένα καλά μελετημένο υβριδικό σύστημα σε οικιακό επίπεδο δύναται να μειώσει συντριπτικά τη χρήση συμβατικών καυσίμων για την ικανοποίηση των ενεργειακών αναγκών των χρηστών μιας οικίας.

description: In this paper, we propose a correlation-regression approach to establish a statistical relationship between acceptance rate & first decision time of some indexed journals. We collect the data from two web sources: Elsevier journal finder, and Springer journal suggester. In this problem, we concentrate on the data of the acceptance rate and first decision time. To examine the relationship between these measures, we apply a statistical approach, which is based on correlation and regression analysis. We determine the relative error (RE) of the data collected. We plot the scatter diagram between the two measures. Karl Pearson correlation coefficient (CC) value is also calculated. All this analysis demonstrates that there is a moderate positive correlation between acceptance rate & first decision time.

description: A theory with a mass scale and yet Weyl invariant is presented. The theory is not invariant under all diffeomorphisms but only under transverse ones. This is the reason why Weyl invariance does not imply scale invariance in a free falling frame. Physical implications of this framework are discussed.

description: Der Einstieg in ein Lehramtsstudium für das Fach Mathematik verläuft für viele Studierende keinesfalls unproblematisch. Nach wie vor prägen hohe Studienabbrecherquoten von bis zu 40 Prozent (je nach Berechnung, siehe Briedis et al., 2008; Dieter et al., 2008) das Bild des Mathematiklehramtsstudiums an vielen Universitäten. Es wird in den letzten Jahren vermehrt diskutiert, welche Maßnahmen von Seiten der Hochschulen und Universitäten ergriffen werden können, um die Lehramtsstudierenden in der kritischen Studieneingangsphase zu unterstützen (vgl. Bruder et al., 2010). Um allerdings wirkungsvolle Maßnahmen ergreifen zu können, ist nicht nur eine systematische Entwicklung und Evaluation von hochschuldidaktischen Maßnahmen erforderlich, sondern auch eine wissenschaftliche Untersuchung von Ausgangsbedingungen auf Seiten der Studierenden. Dazu möchte der vorliegende Artikel einen Beitrag leisten.

description: We study the stochastic variation of blazar emission under a 2-D spatially resolved leptonic jet model we previously developed. Random events of particle acceleration and injection in small zones within the emission region are assumed to be responsible for flux variations. In addition to producing spectral energy distributions that describe the observed flux of Mrk 421, we further analyze the timing properties of the simulated light curves, such as the power spectral density (PSD) at different bands, flux-flux correlations, as well as the cross-correlation function between X-rays and TeV γ-rays. We find spectral breaks in the PSD at a timescale comparable to the dominant characteristic time scale in the system, which is usually the pre-defined decay time scale of an acceleration event. Cooling imposes a delay, and so PSDs taken at lower energy bands in each emission component (synchrotron or inverse Compton) generally break at longer timescales. The flux-flux correlation between X-rays and TeV γ-rays can be either quadratic or linear, depending on whether or not there are large variation of the injection into the particle acceleration process. When the relationship is quadratic, the TeV flares lag the X-ray flares, and the optical & GeV flares are large enough to be comparable to the ones in X-ray. When the relationship is linear, the lags are insignificant, and the optical & GeV flares are small.

description: In this paper, we propose a Spin-Torque (ST) based sensing scheme that can enable energy efficient multi-bit long distance interconnect architectures. Current-mode interconnects have recently been proposed to overcome the performance degradations associated with conventional voltage mode Copper (Cu) interconnects. However, the performance of current mode interconnects are limited by analog current sensing transceivers and equalization circuits. As a solution, we propose the use of ST based receivers that use Magnetic Tunnel Junctions (MTJ) and simple digital components for current-to-voltage conversion and do not require analog transceivers. We incorporate Spin-Hall Metal (SHM) in our design to achieve high speed sensing. We show both single and multi-bit operations that reveal major benefits at higher speeds. Our simulation results show that the proposed technique consumes only 3.93-4.72 fJ/bit/mm energy while operating at 1-2 Gbits/sec; which is considerably better than existing charge based interconnects. In addition, Voltage Controlled Magnetic Anisotropy (VCMA) can reduce the required current at the sensor. With the inclusion of VCMA, the energy consumption can be further reduced to 2.02-4.02 fJ/bit/mm

description: The amyloid $β$ peptide (A$β$42), whose aggregation is associated with Alzheimer's disease, is an amphiphatic peptide with a high propensity to self-assemble. A$β$42 has a net negative charge at physiological pH and modulations of intermolecular electrostatic interactions can significantly alter its aggregation behaviour. Variations in sequence and solution conditions lead to varied macroscopic behaviour, often resulting in a number of different mechanistic explanations for the aggregation of these closely related systems. Here we alter the electrostatic interactions governing the fibril aggregation kinetics by varying the ionic strength over an order of magnitude, which allows us to sample the space of different reaction mechanisms, and develop a minimal reaction network that explains the experimental kinetics under all the different conditions. We find that an increase in the ionic strength leads to an increased rate of surface catalysed nucleation over fragmentation and eventually to a saturation of this nucleation process. More generally, this reaction network connects previously separate systems, such as mutants of A$β$42 and the wild type, on a continuous mechanistic landscape, thereby providing a unified picture of the aggregation mechanism of A$β$42 and the means of directly comparing the effects of intrinsic modifications of the peptide to those of simple electrostatic shielding.

description: BINGO ist ein sehr einfaches Spiel. Man hat dabei eigentlich keine Strategien zu verfolgen, sondern muss nur schnell sein, das ist alles, was man selbst steuern kann. Trotzdem besitzt BINGO interessante stochastische Aspekte, welche im Folgenden behandelt werden sollen, z. B. wie viele Ziehungen muss man im Durchschnitt abwarten, bis man „BINGO!“ rufen kann? Oder: Wie wahrscheinlich ist es, dass man erst nach der letzten gezogenen Kugel „BINGO!“ rufen kann? Welche Anzahl der nötigen Ziehungen, bis man „BINGO!“ rufen kann, ist die wahrscheinlichste?
