successively finer steps. BIRD’S EYE VIEW The CPHT (acronym for Centre de Physique Théorique) is a Mixed Research Unit (UMR is the French acronym) between the CNRS and the Ecole Polytechnique. It was created in 1958 by Louis Michel. Snapshot view as of June 30 2018. The CPHT has 80 members.† This number is composed as fol- lows. The permanent research staff consists of 36 people: • 23 CNRS Researchers; • 2 Research Engineers at Ecole Polytechnique; • 5 Teachers-Researchers (4 at Ecole Polytechnique and 1 Professor at Collège de France‡) ); • 6 Emeritus Senior Researchers at CNRS. There are 19 PhD theses in progress and 18 Postdoctoral Fellows. The administrative staff consists of 4 people and the IT staff consists of 2 people. Structure of the CPHT as of June 30 2018. The lab is structured in six groups. We indicate the number of permanent researchers for each group in parentheses, without counting Emeritus Senior Researchers at CNRS. This structure is the same as that of the previous 5-year period. RESEARCH GROUPS CONDENSED MATTER (7) LASER PLASMA INTERACTION (2.6) MAGNETIZED PLASMAS (5.4) MATHEMATICAL PHYSICS (4) PARTICLE PHYSICS (5) STRING THEORY (6) Note: there is a researcher working for two groups, which explains the non-integer values. A few figures. The following figures are relevant indicators of the vitality of the CPHT: • about 530 publications in international refereed journals for the 2013-2018 period; • about 1400 “missions” for the 2013-2018 period. By “missions” we mean invitations of researchers at the CPHT, or researchers from the CPHT going to other labs or to conferences in France and abroad; • 3 ongoing ERC grants (one “Starting”, one “Consolidator”, and one “Synergy”) / 9 ANR projects (8 of them managed by the CPHT), with 5 ongoing ones / 3 EUROfusion projects / 1 Simons Foundation grant; • 21 defended PhD theses during the 2013-2018 period, and 19 PhD theses in progress. †One should also aggregate the visitors and undergraduate interns to have the effective size of the lab. ‡A formalization

  • Globalfs: a Strongly Consistent Multi-Site File System
    GlobalFS: A Strongly Consistent Multi-Site File System Leandro Pacheco Raluca Halalai Valerio Schiavoni University of Lugano University of Neuchatelˆ University of Neuchatelˆ Fernando Pedone Etienne Riviere` Pascal Felber University of Lugano University of Neuchatelˆ University of Neuchatelˆ Abstract consistency, availability, and tolerance to partitions. Our goal is to ensure strongly consistent file system operations This paper introduces GlobalFS, a POSIX-compliant despite node failures, at the price of possibly reduced geographically distributed file system. GlobalFS builds availability in the event of a network partition. Weak on two fundamental building blocks, an atomic multicast consistency is suitable for domain-specific applications group communication abstraction and multiple instances of where programmers can anticipate and provide resolution a single-site data store. We define four execution modes and methods for conflicts, or work with last-writer-wins show how all file system operations can be implemented resolution methods. Our rationale is that for general-purpose with these modes while ensuring strong consistency and services such as a file system, strong consistency is more tolerating failures. We describe the GlobalFS prototype in appropriate as it is both more intuitive for the users and detail and report on an extensive performance assessment. does not require human intervention in case of conflicts. We have deployed GlobalFS across all EC2 regions and Strong consistency requires ordering commands across show that the system scales geographically, providing replicas, which needs coordination among nodes at performance comparable to other state-of-the-art distributed geographically distributed sites (i.e., regions). Designing file systems for local commands and allowing for strongly strongly consistent distributed systems that provide good consistent operations over the whole system.

  • Towards Transparent Data Access with Context Awareness
    Computer Science • 19(2) 2018 https://doi.org/10.7494/csci.2018.19.2.2844 Micha lWrzeszcz Renata G. S lota Jacek Kitowski TOWARDS TRANSPARENT DATA ACCESS WITH CONTEXT AWARENESS Abstract Open-data research is an important factor accelerating the production and analysis of scientific results as well as worldwide collaboration; still, very little dataEarly is being shared at scale. The aim of this bird article is to analyze existing data-access solutions along with their usage limitations. After analyzing the existing solutions and data-access stakeholder needs, the authors propose their own vision of a data-access model. Keywords distributed, transparent data access, distributed data storage, context awareness Citation Computer Science 19(2) 2018: 201{221 201 202 Micha Wrzeszcz, Jacek Kitowski, Renata S lota 1. Introduction Data access and management can be analyzed on several levels; from personal data to globally distributed shared data with different problems to be overcome by data access and management tools. The simplest case is access to local data; i.e., data stored on direct attached storage (DAS), where the focus is on providing the device drivers and solutions that use the hardware optimally. The next level is to provide data access for a group of users working for a single organization; e.g., provision of network attached storage (NAS). The problems en- countered in this case pertain to possible network failures, higher latencies [36], or the simultaneous work of many users influencing the quality of service [48, 59]. The balance of use of available storage systems to maintain QoS and cost effectiveness in an organization while request scheduling and resource allocation is also expected [28,56].
