        Selecting a Business-Process-Management-System in conjunction with an Identity-and-Access-Management-System 30m
        Business processes are integral parts of every day (non-technical) administrative tasks. Many of these tasks at DESY are still paper-bound. A joint project of DESY-Administration and High-Energy-Physics department was started to provide the organisational and technical prerequisites for establishing electronic workflows by using business process management systems (BPMS) as well as an identity and access management (IAM) system. Thus processes will be handled faster, be traceable better and executed in a uniform manner. The presentation will show aspects of the procedures in choosing a BPM-system as well as an IAM-system and underlying requirements.

        ZNeTS: log your network traffic ! 25m
        ZNeTS is an acronym for "The Network Traffic Supervisor". It is a tool for monitoring and recording machines traffic during months. ZNeTS is a network tool for network introspection and a response to the legal need, in France, to store one year traffic traces. ZNeTS is very easy to deploy whatever the architecture of your network. ZNeTS identifies compromised local machines (by virus, trojans, abusive or illegal usage, DNS or Mac spoofing, etc...). ZNeTS graphical interface is intuitive and ergonomic. Integrated metrology features offer two levels of details. Alerts are simple and relevant. Over the last 6 month, the tool has been successfully deployed as an appliance into all the IN2P3 laboratories (the french national research institute in physics) and we gave very positive feedbacks from the System administrators.

        Testing SLURM batch system for a grid farm: functionalities, scalability, performance and how it works in a GRID environment 30m
        We will show all the work done in order to install and configure the batch system itself together with the security configuration needed. In this presentation we will show the results of the deep testing that we have done on SLURM, in order to be sure that it will cover all the needed functionalities like: priorities, fairshare, limits, QoS, failover capabilities and others. We will report also on the possibility of exploiting this batch system within a complex mixed farm environment where grid job, local job and interactive activities are managed exploiting the same batch system. From a point of view of the scalability we will show how the SLURM batch system is able to deal with the increasing number of node, CPU and jobs served. We will also show the performance achieved with several client accessing the same batch server. We also will make some comparison with other available open source batch system both in terms of performance and functionalities. We will also provide feedback on mixed configuration with SLURM and MAUI as job scheduling. We will also describe the work done in order to support SLURM in a EGI grid environment.

        Bringing cloud storage to your desk with Mucura 30m
        In this contribution we present our experience building a prototype of an open source software system for operating online file repositories of extensible capacity. Built on the well-understood client-server architecture model, the system can be used by computing centers looking at solutions for providing online storage services for their individual users. The client-side component runs on the end-user’s personal computer and provides both command-line and graphical user interfaces. It supports a deliberately limited set of operations on remote files, namely store, retrieve, organize and share remote files. Mucura exposes the same HTTP-based standard API supported by Amazon S3 and extends it to support the certificate-based authentication mechanism used by production grid computing platforms such as WLCG. As a consequence, personal file repositories based on Mucura can be seamlessly accessed both from the user’s personal computer and from grid jobs running on the user’s behalf. This integration allows researchers to use their individual online storage space as a personal storage element conveniently managed from their personal computer. At the core of the system there are components for managing file metadata and for secure storage of the files’ contents, implemented on top of highly available, distributed, persistent and scalable key-value stores. We will present a detailed architectural view of the system, the status of development and the perspectives for the months to come. This work is inspired not only by the increasing number of commercial services available nowadays to individuals for their personal storage needs (backup, file sharing, synchronization, …) such as Amazon S3, Dropbox, SugarSync, bitcasa, etc., but also by several efforts in the same area in the academic and research worlds (NASA, SDSC, etc.). We are persuaded that the level of flexibility offered to individuals by this kind of systems adds value to the day-to-day work of scientists.

        CERN and Helix Nebula, the Science Cloud 30m
        Helix Nebula, the Science Cloud, is a collaborative effort of several European organizations, including CERN, ESA and EMBL, to engage with European industry in public-private partnerships to build a European cloud infrastructure capable of supporting the missions of these organisations. During the initial pilot phase of Helix Nebula, the ATLAS experiment at CERN was selected as one of the flagship projects and a proof-of-concept phase was defined in order to demonstrate the feasibility of integrating commercial cloud facilities into the ATLAS distributed computing infrastructure. This talk will outline the status of Helix Nebula and present the results of the ATLAS use-case in particular. Three commercial cloud providers with varied infrastructures were tested; all were successfully able to run ATLAS simulation jobs, though the paths to success at some providers were more difficult than others. We will give an insight into the lessons learned, the technical recommendations for the suppy side and some of the future work in the Helix Nebula partnership.

        Mobile web development, and CERN mobile web site 30m
        Mobile computing is clearly on the rise – but developing mobile applications, especially for multiple platforms, is a considerable effort. Fortunately, there is an alternative to native apps: web sites that are optimized for mobile devices and touch screens. In this presentation, I will discuss both solutions, and will present a hybrid approach. The presentation will also include a brief introduction to technologies such as jQuery, jQuery Mobile and PhoneGap. Additionally, as an example of a mobile web application, CERN mobile web site (http://m.cern.ch) will be presented.

        Service Provisioning and Security Guarantee in CSTNET 30m
        CSTNET is the non-profitable, nationwide academic network in China, with the aim of providing Internet service and applications for the demand of scientific research and constructing an innovative network environment for the future ICT. The service provisioning and security guarantee are key factors to ensure the success of an operational network. In this talk, we will first give an overview of CSTNET, followed by the introduction of its infrastructure. And then, we will demonstrate the advanced scientific network services and applications provided by CSTNET. The main services include the network management cloud service, network security cloud service, unified communication service, Duckling collaboration working environment service, and network research and experimentation service. The main network applications include light-path provisioning for eVLBI and its tracking for Chang’E-1&2 Lunar Mission, massive data transmission for IHEP-NERSC Daya Bay neutrino experiment, and integrated services for ITER. Finally, we will present how to guarantee the security in CSTNET, which is provided by the network security infrastructure and the security cloud platform. The network security cloud delivers a clear and achievable path for network administrators using SAAS paradigm to achieve the centralized and unified monitoring and to provide multitenant, on-demand, location-independent network security services. Based on the security facilities and security operating center, both personalized special services and cloud-based general services are provided for 100 institutions in CAS, including security monitoring and situation awareness service, malicious code in-depth analysis service, emergency response on information security service, security assessment and reinforcement service, and safety training service.
