Algorithms and Scheduling Techniques to Manage Resilience and Power Consumption in Distributed Systems (Dagstuhl Seminar 15281)

Authors: Henri Casanova, Ewa Deelman, Yves Robert, and Uwe Schwiegelshohn

Abstract
Large-scale systems face two main challenges: failure management and energy management. Failure management, the goal of which is to achieve resilience, is necessary because a large number of hardware resources implies a large number of failures during the execution of an application. Energy management, the goal of which is to optimize of power consumption and to handle thermal issues, is also necessary due to both monetary and environmental constraints since typical applications executed in HPC and/or cloud environments will lead to large power consumption and heat dissipation due to intensive computation and communication workloads. The main objective of this Dagstuhl seminar was to gather two communities: (i)~system-oriented researchers who study high-level resource-provisioning policies, pragmatic resource allocation and scheduling heuristics, novel approaches for designing and deploying systems software infrastructures, and tools for monitoring/measuring the state of the system; and (ii)~algorithm-oriented researchers, who investigate formal models and algorithmic solutions for resilience and energy efficiency problems. Both communities focused around workflow applications during the seminar, and discussed various issues related to the efficient, resilient, and energy efficient execution of workflows in distributed platforms. This report provides a brief executive summary of the seminar and lists all the presented material.

The Constraint Satisfaction Problem: Complexity and Approximability (Dagstuhl Seminar 15301)

Authors: Andrei A. Bulatov, Venkatesan Guruswami, Andrei Krokhin, and Dániel Marx

Abstract
During the past two decades, an impressive array of diverse methods from several different mathematical fields, including algebra, logic, mathematical programming, probability theory, graph theory, and combinatorics, have been used to analyze both the computational complexity and approximabilty of algorithmic tasks related to the constraint satisfaction problem (CSP), as well as the applicability/limitations of algorithmic techniques. This research direction develops at an impressive speed, regularly producing very strong and general results. The Dagstuhl Seminar 15301 "The Constraint Satisfaction Problem: Complexity and Approximability" was aimed at bringing together researchers using all the different techniques in the study of the CSP, so that they can share their insights obtained during the past three years. This report documents the material presented during the course of the seminar.

Digital Scholarship and Open Science in Psychology and the Behavioral Sciences (Dagstuhl Perspectives Workshop 15302)

Authors: Alexander Garcia Castro, Janna Hastings, Robert Stevens, and Erich Weichselgartner

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 15302 "Perspectives Workshop: Digital Scholarship and Open Science in Psychology and the Behavioral Sciences". This workshop addressed the problem of facilitating the construction of an integrative digital scholarship and open science infrastructure in psychology and the behavioral sciences by utilizing the Web as an integrative platform for e-Science. A particular focus was on sharing research data and experiments to improve reproducibility. The participants presented first steps in this direction in their communities, and worked out an initial action plan for establishing digital scholarship and open science more broadly.
