Easing Scientific Computing and Federated Management in The
Easing Scientific Computing and Federated Management in the Cloud with OCCI Zdenekˇ Sustrˇ 1, Diego Scardaci2,3, Jirˇ´ı Sitera1, Boris Parak´ 1 and V´ıctor Mendez´ Munoz˜ 4 1Department of Distributed Computing, CESNET, Zikova 4, 160 00, Praha 6, Czech Republic 2European Grid Initiative, Science Park 140, 1098 XG Amsterdam, Netherlands 3INFN Sezione di Catania, Via S. Sofia 64, I-95123 Catania, Italy 4Computer Architecture & Operating Systems Department (CAOS), Universitat Autonoma` de Barcelona (UAB), Bellaterra, Spain Keywords: Federated Cloud, Cloud Standards, Cloud Interoperability, Cloud Solution Design Patterns, Cloud Application Architectures, Cloud Middleware Frameworks, Open Cloud Computing Interface. Abstract: One of the benefits of OCCI stems from simplifying the life of developers aiming to integrate multiple cloud managers. It provides them with a single protocol to abstract the differences between cloud service implemen- tations used on sites run by different providers. This comes particularly handy in federated clouds, such as the EGI Federated Cloud Platform, which bring together providers who run different cloud management plat- forms on their sites: most notably OpenNebula, OpenStack, or Synnefo. Thanks to the wealth of approaches and tools now available to developers of virtual resource management solutions, different paths may be cho- sen, ranging from a small-scale use of an existing command line client or single-user graphical interface, to libraries ready for integration with large workload management frameworks and job submission portals relied on by large science communities across Europe. From lone wolves in the long-tail of science to virtual or- ganizations counting thousands of users, OCCI simplifies their life through standardization, unification, and simplification. -

KDE Plasma 5
Arvo Mägi KDE Plasma 5 Tallinn, 2017 1 Sissejuhatus KDE töökeskkonnale pani aluse saksa programmeerija Matthias Ettrich 14.10.1996. 2016. a oktoobris sai populaarne KDE seega 20. aastaseks. Hea ülevaate KDE ajaloost annab artikkel „19 Years of KDE History: Step by Step.” KDE 4.14 ilmumisega oli KDE saavutanud kasutusküpsuse, kuid edasine areng kippus takerduma – vaja oli põhimõttelisi uuendusi. Otsustati võtta kasutusele iseseisvatel moodulitel põhinev KDE 5 arhitektuur – Qt/Frameworks. Kõik KDE rakendusprogrammid, sh Plasma 5 töölaud, kasutavad ainult konkreetse rakenduse jaoks vajalikke mooduleid. Varem kasutati kõigi rakenduste jaoks ühist suurt teeki, mis raskendas muudatuste tegemist ja pidurdas arendustööd. Qt on C++ programmeerimiskeskkond. Pikaajalise toega Qt 5.9 LTS ilmus 31. mail 2017. KDE Frameworks on 70 moodulist koosnev komplekt, mis lihtsustab Qt keskkonnas KDE programmide koostamist. Frameworks veaparandused ja täiendused ilmuvad iga kuu. KDE Plasma 5 töölaud põhineb KDE Frameworksil (KF5). Töölaua veaparandused ilmuvad iga kuu, vajadusel mitu korda kuus, uued versioonid kord kvartalis. Plasma 5.8 LTS, mis on pikaajalise toega (18 kuud), ilmus 4.10.2016, veidi enne KDE 20. aastaseks saamist. Plasma 5.10 ilmus 30.05.2017. Järgmine pikaajalise toega Plasma 5.12 ilmub 2018. a jaanuaris. Plasma 5 töölaud on pälvinud palju kiitvaid hinnanguid ja sobib igapäevaseks tööks. Eeldab kaasaegset, mitme tuumaga protsessori ja piisava mäluga (vähemalt 4 GB) arvutit. SSD kettalt töötab välkkiirelt. Töölaud on keskkond rakendusprogrammide käivitamiseks ja kasutamiseks. KF5-le on üle viidud kõik KDE põhirakendused (failihaldur Dolphin, pildinäitaja Gwenview, konsool Konsole, teksti- redaktor Kate, ekraanitõmmise võtja Spectacle, videoredaktor Kdenlive, plaadikirjutaja K3b jt). Need on KDE Applications koosseisus, mille uued versioonid ilmuvad kolm korda aastas, veaparandused kord kuus. -

D1.3 Production System
REPORT FOR DELIVERABLE D1.3 1 1 INTRODUCTION This report provides an overview of the technical characteristics and functionality of deliverable D1.3 “Production System”. Its purpose is to provide a short introduction to the processes designed and implemented enabling the final production installation (g eodata.gov.gr) of the various software developed and reused by PublicaMundi . The reader is encouraged to visit the software’s repository (https://github.com/PublicaMundi) to receive: Up-to-date versions of the software, along with documentation targeted to developers Detailed information regarding all development effort (commits, activity, issues) Instructions regarding the installation of the software and its dependencies 2 2 DESCRIPTION OF TASK PublicaMundi aims to make open geospatial data easier to discover, reuse, and share by fully supporting their complete publishing lifecycle in open data catalogues. To achieve this, we are extending and integrating leading open source software for open data publishing and geos patial data management. The goal of Task 1.3 is to apply agile development principles with periodic integration in order to maintain relevant contributions. Integration is performed on labs.geodata.gov.gr, a beta-testing facility, where new functionalities are tested on real data and users. New versions are being deployed automatically and user feedback is collected with online tools bringing them in contact with developers. For the purposes of our production deployment, we built upon our first deployment of labs.geodata.gov.gr, extending our integration environment (D1.2) and through automation procedures we established the production environment. On this environment, a stable version of the software has been rolled out, after extensive testing of the components of PublicaMundi. -
