Electronic Ticket and Check-in System for Indico Conferences

Project Specification: This project should build on the existing participant registration module of Indico and provide additional functionalities for managing the check-in process. While in small conferences it is easy to keep track of participants with a simple paper list, such techniques become inefficient when the need to scale the process up arises. Therefore Indico’s participant registration module would be extended with the functionality to generate electronic tickets. This will allow conference organizers to keep track of attendees after they finish the registration process. As part of this project it is also necessary to develop a mobile application that will be used to scan the electronic tickets, identify the user and mark them as checked in when they arrive at the conference. Additionally Indico’s HTTP API would be extended to be used by the mobile application to retrieve data about conferences and attendees. Abstract: The main goal of this project is to simplify the check-in process for conferences that use the Indico conference management system. This is archived by extending Indico’s core to include electronic ticket generation functionality and developing a mobile application that is used to scan the electronic tickets during the check-in process. Indico’s HTTP API is also extended to provide the mobile application with the necessary data

Integration of cloud services with Invenio digital library

Project Specification: Connect Invenio digital library with popular cloud storage services such as Google Drive, Dropbox and Sky Drive. Abstract: Cloudutils is a standalone python module which provides an interface to popular cloud storage services (e.g. Google Drive, Skydrive…). It is built on top of the PyFilesystem module. In this project Cloudutils module was developed and used to connect Invenio digital library and popular cloud storage services

Evaluation of standard monitoring tools(including log analysis) for control systems at Cern

Project Specification: The goal of this Openlab Summer Student project was to assess the implications and the benefits of integrating two standard IT tools, namely Icinga and Splunkstorm with the existing production setup for monitoring and management of control systems at CERN. Icinga – an open source monitoring software based on Nagios would need to be integrated with an in-house developed WinCC OA application called MOON, that is currently used for monitoring and managing all the components that make up the control systems. Splunkstorm – a data analysis and log management online application would be used stand alone, so it didn’t need integration with other software, only understanding of features and installation procedure. Abstract: The aim of this document is to provide insights into installation procedures, key features and functionality and projected implementation effort of Icinga and Splunkstorm IT tools. Focus will be on presenting the most feasible implementation paths that surfaced once both software were well understood

Using a new multivariate technique in high energy physics

This project focuses on testing and developing algorithms for multivariate data analysis, that separate signal processes from abundant backgrounds and on helping with organizing and filtering colossal amounts of raw data, gathered from the Large Hadron Collider beauty (LHCb) experiment, to find extremely rare events of interest. Moreover, working on this project also meant trying to apply new, faster method to take the place of systems that are now used at CERN to pare down the relevant data, but require relatively extensive processing and analysis to determine relevance and usefulness

CERN openlab Whitepaper on Future IT Challenges in Scientific Research

This whitepaper describes the major IT challenges in scientific research at CERN and several other European and international research laboratories and projects. Each challenge is exemplified through a set of concrete use cases drawn from the requirements of large-scale scientific programs. The paper is based on contributions from many researchers and IT experts of the participating laboratories and also input from the existing CERN openlab industrial sponsors. The views expressed in this document are those of the individual contributors and do not necessarily reflect the view of their organisations and/or affiliates

Advanced Visualizations Tools for CERN Institutional Data

Project Specification: The aim of this openlab summer student project is to provide intuitive and powerful visualisation tools for key institutional data about CERN, including budgets and contracts. The project will be done in collaboration with the Open Knowledge Foundation under the framework of CERN's open data policy regarding scientific results from LHC. The student will use the model-view-controller web development framework with Flask/HTML5/jQuery/TwitterBootstrap technologies for the user interface and SQLAlchemy ORM for database persistence. Abstract: CERN’s Open Access Policy says that “all results of its experimental and theoretical work shall be published or otherwise made generally available”. Following that, CERN has reached a collaboration agreement with the Open Knowledge Foundation in order for CERN to publish and visualize institutional data. As part of this collaboration, we will develop a module for showing this data in a graphical way in the CERN side and a tool in the Open Knowledge Foundation site for automatizing the input of data

Improvement of the IT-PES-PS Section Services Statistics Page

Project Specification: The IT-PES-PS service managers gather a lot of statistics for the services they run. These statistics are currently displayed by SLS (Service Level Status) or Lemon pages. They also use the Web interface provided with OpenTSDB, a DB optimised for time series. And while these various pages give very useful and technical information, they do not always emphasise the important figures. Having different statistics pages makes it difficult to see the relevant numbers at once. The goal of this project was to build homogeneous dashboards with interactive plots to better reflect the activity and resources of each service, showing relevant figures at first sight in a single website. Abstract: There is a need in the IT-PES-PS section to improve the current situation of having to consult the relevant information from several heterogeneous websites by introducing interactive homogeneous dashboards, accessible from a single web application where the information needed can be quickly accessed. The goal of this openlab Summer Student project was to create a website with homogeneous and interactive dashboards. Its architecture had to allow the creation of new dashboards easily

Integration of Network Performance Monitoring Data at FTS3

Project Specification: The main goal of this project is to optimize the tcp buffer size to make more efficient the file transfers with FTS3. The library that has been implemented provides a way to calculate this providing a source and a destination. This way, whoever is transferring the files does not have to know anything about the logic of how calculate it. In this project, I have done a library to make easy the access to PerfSONAR’s information between two hosts, calculating the optimized tcp buffer size and thereby to making more efficient the transfer of files. As part of my work, I have also tested the library to check if it actually improved the transfer throughput with tools as GridFTP and Globus

CERN Storage Systems for Large-Scale Wireless

The project aims at evaluating the use of CERN computing infrastructure for next generation sensor networks data analysis. The proposed system allows the simulation of a large-scale sensor array for traffic analysis, streaming data to CERN storage systems in an efficient way. The data are made available for offline and quasi-online analysis, enabling both long term planning and fast reaction on the environment

Prepare for Citizen Science Challenges at CERN

Abstract: To inspire more people to contribute to science, and educate the public about science, two Citizen Science "challenges" were prepared during summer 2013: the CERN Summer Webfest 2013 and the Virtual LHC Challenge. The first part of this report summarizes how to organize a Webfest at CERN and the outcome of the CERN Summer Webfest 2013.The second part gives an introduction to the current state of the Virtual LHC Challenge: a development of the LHC@Home Test4Theory project planned to attract many unskilled volunteers. This work was supported by a grant from the EU Citizen Cyberlab project, with assistance from the Citizen Cyberscience Centre (CCC)
