Indico: A Collaboration Hub
/ Ferreira, P (CERN) ; Baron, T (CERN) ; Bossy, C (CERN) ; Gonzalez, J B (CERN) ; Pugh, M (CERN) ; Resco, A (CERN) ; Trzaskoma, J (CERN) ; Wachter, C (CERN)
Since 2009, the development of Indico has focused on usability, performance and new features, especially the ones related to meeting collaboration. Usability studies have resulted in the biggest change Indico has experienced up to now, a new web layout that makes user experience better. [...]

Characterisation of HEP database applications
/ Piorkowski, Mariusz (CERN) ; Grancher, Eric (CERN) ; Topurov, Anton (CERN)
Oracle-based database applications underpin many key aspects of operations for both the LHC accelerator and the LHC experiments. In addition to the overall performance, the predictability of the response is a key requirement to ensure smooth operations—and delivering predictability requires understanding the applications from the ground up. [...]

Designing and developing portable large-scale JavaScript web applications within the Experiment Dashboard framework
/ Andreeva, J (CERN) ; Dzhunov, I (CERN) ; Karavakis, E (CERN) ; Kokoszkiewicz, L (CERN) ; Nowotka, M (CERN) ; Saiz, P (CERN) ; Tuckett, D (CERN)
Improvements in web browser performance and web standards compliance, as well as the availability of comprehensive JavaScript libraries, provides an opportunity to develop functionally rich yet intuitive web applications that allow users to access, render and analyse data in novel ways. However, the development of such large-scale JavaScript web applications presents new challenges, in particular with regard to code sustainability and team-based work. [...]

Management of virtualized infrastructure for physics databases.
/ Topurov, A (CERN) ; Gallerani, L (CERN) ; Chatal, F (CERN) ; Piorkowski, M (CERN)
Demands for information storage of physics metadata are rapidly increasing together with the requirements for its high availability. Most of the HEP laboratories are struggling to squeeze more from their computer centers, thus focus on virtualizing available resources. [...]

Why are common quality and development policies needed?
/ Alandes, M (CERN) ; Abad, A (CERN) ; Guerrero, P (CERN)
The EMI project is based on the collaboration of four major middleware projects in Europe, all already developing middleware products and having their pre-existing strategies for developing, releasing and controlling their software artefacts. In total, the EMI project is made up of about thirty development individual teams, called “Product Teams” in EMI. [...]

Distributed Monitoring Infrastructure for Worldwide LHC Computing Grid
/ Andrade, Pedro (CERN) ; Babik, Marian (CERN) ; Bhatt, Kislay (Bhabha Atomic Res. Ctr.) ; Chand, Phool (Bhabha Atomic Res. Ctr.) ; Collados, David (CERN) ; Duggal, Vibhuti (Bhabha Atomic Res. Ctr.) ; Fuente, Paloma (CERN) ; Hayashi, Soichi (Indiana U.-Purdue U., Indianapolis) ; Imamagic, Emir (Zagreb U.) ; Joshi, Pradyumna (Bhabha Atomic Res. Ctr.) et al.
The journey of a monitoring probe from its development phase to the moment its execution result is presented in an availability report is a complex process. It goes through multiple phases such as development, testing, integration, release, deployment, execution, data aggregation, computation, and reporting. [...]

Experiences with Software Quality Metrics in the EMI middlewate
/ Alandes, M (CERN) ; Kenny, E M (Trinity College) ; Meneses, D (CERN) ; Pucciani, G (CERN)
The EMI Quality Model has been created to define, and later review, the EMI (European Middleware Initiative) software product and process quality. A quality model is based on a set of software quality metrics and helps to set clear and measurable quality goals for software products and processes. [...]

Web enabled data management with DPM & LFC
/ Alvarez Ayllon, A ; Beche, A ; Fabrizio, F ; Hellmich, M ; Keeble, O ; Brito da Rocha, R
The Disk Pool Manager (DPM) and LCG File Catalog (LFC) are two grid data management components currently used in production with more than 240 endpoints. Together with a set of grid client tools they give the users a unified view of their data, hiding most details concerning data location and access. [...]
