        Signing (and encrypted) message handling and implications for admins. 30m
        In grid computing we use an X509 PKI security infrastructure. This infrastructure is used to enable secure connections between hosts to deliver payload. This often leads to scalability and reliability issues. This talk presents the alternative approach of signing messages for asynchronous handling, allowing authentication of the payload rather than the connection. The implications of this approach will be illustrated showing how service interdependency can be reduced, and clustering simplified. AMQP (RabbitMQ) will be used as a transport mechanism in this talk to illustrate these concepts. Both the openssl command line and a python library can be used to authenticate signed messages making scalable secure authentication between sites resources practical for administrators.

        OpenMP Performance on Virtual Machines 30m
        Virtualization technology has been applied to a variety of areas including server consolidation, High Performance Computing, as well as Grid and Cloud computing. Due to the fact that applications do not run directly on the hardware of a host machine, virtualization generally causes a performance loss for both sequential and parallel applications. This talk studies the OpenMP applications running on a virtualized multicore machine. It shows the overhead of parallelization and compares the parallel performance on virtual machines with the performance of native executions. An interesting scenario is that one application runs much slower in parallel than the sequential runs. A performance analysis tool is then applied to investigate the cause of such abnormal behavior. The talk demonstrates the performance optimization and the results based on the analysis.

        Lustre at GSI 30m
        Lustre has been employed with great success as the general purpose distributed file system for all experimental and theory groups at GSI. Currently there are 100 mio files stored on Lustre, and between batch nodes, interactive nodes and desktops there are ca. 500 clients with access to Lustre. Past issues with stability have been overcome by running the Lustre 1.8 version. Hardware upgrades of metadata servers and OSS are under way. The total file space will increase to > 2 PB soon.

        Evaluation of distributed file systems using trace and replay mechanism 30m
        Reliable benchmarking of file systems is a complex and time consuming task when one has to test against a production environment to achieve relevant results. In case of the HEP community, this eventually leads to setting up a particular experiments' software environment, which could be a rather complicated task for a system administrator. To simplify this task, we developed an application for exact replaying of IO requests to reliably replicate an IO behavior of the original applications without a need of installing the whole working environment. Using the application, we present performance comparison of Lustre, GPFS and Hadoop file systems by replaying traces of LHCb, CMS and ATLAS jobs.

        Implementing Service Management processes with Service-Now 30m
        The choice of Service-Now as a tool for handling the request fulfillment and incident management ITIL processes in the IT and the General Services Departments at CERN has created several months of intensive development. Besides the implementation of these two standardized ITIL process it has been a very interesting task to model CERN Service catalogue in the tool. The integration with third party systems and workflows, as SSO, GGUS, organization data, knowledge base, has started and will be a running task for the next couple of years. The biggest challenge will be the transition of existing non-ITIL processes implemented in other tools into Service-Now.

        Moving virtual machines images securely between sites. 30m
        A Grid service allows applications to the run on many sites without modification. Virtualization provides the potential for deploying the same customized operating system at many sites. This talk will present one of many possible security infrastructures and models to allow sharing and deployment of virtual machines images that meets the objectives of secure non-repudiation of images, auditing and fault tolerance that has been developed within the HEPIX virtualization working group. The talk focus will be made on the meta data describing the virtual machines, how to share this meta data, how to share the image described and to verify an image adn its meta data, presenting packages and deployment, and how to audit the approach.

        StratusLab Marketplace for Sharing Virtual Machine Images 30m
        StratusLab (http://stratuslab.eu/) provides a complete, open-source solution for deploying an "Infrastructure as a Service" cloud infrastructure. Use of the cloud requires the use of prepared machine and disk images, yet preparing correct, secure images remains difficult and represents a significant barrier to the adoption of cloud technologies. The StratusLab Marketplace is an image registry, containing cryptographically signed metadata associated with shared images. It simultaneously allows: end-users to search for existing images, image creators to publicize their images, and cloud administrators to evaluate the trustworthiness of an image. The image files themselves are stored elsewhere--either in cloud storage or in web-accessible repositories. The StratusLab Marketplace facilitates the sharing of images and use of IaaS cloud infrastructures, allowing users access to a diverse set of existing images and providing cloud administrators with the confidence to allow them to run. Its integration with the StratusLab distribution makes use of registered images easy, further reducing barriers to adoption.

        Operating a distributed IaaS Cloud for BaBar MC production and user analysis 30m
        In the last year we have established a system which replicates a standard Condor HTC environment across multiple distinct IaaS clouds of different types including EC2, Nimbus and Eucalyptus. Users simply submit batch jobs to a Condor queue containing a custom attribute which is a pointer to the Virtual Machine Image they would like booted to service their job. The system automatically boots instances of the requested machine type on one of the available clouds and contextualizes them to connect to the batch system. The system is being used on a continual basis for astronomy and HEP jobs. We report on our experience operating this system which has booted over 30 000 VMs and completed over 250 000 jobs.

        Adopting Infrastructure as Code to run HEP applications 30m
        GSI is a German national laboratory for heavy-ion beams, planning to build the new accelerator complex "Facility for Antiproton and Ion Research" (FAIR). In preparation for the Tier-0 computing center for FAIR different Infrastructure as a Service (IaaS) cloud technologies have been compared, to construct a private cloud. Simultaneously, effort has been taken to learn how to efficiently execute HEP applications in a virtual environment. The result is a private cloud testbed, called SCLab, build with the help of the OpenNebula toolkit. The concept Infrastructure as Code (IaC), based on the Chef configuration management system, has been adopted for the deployment and operation of HEP applications in clouds. Tools have been developed to start virtual clusters in any IaaS cloud on demand. The first successful applications are a completely virtual AliEn grid site for the ALICE experiment at LHC and simulations for radiation protection studies for FAIR. The talk will present the design decisions and the experience in running HEP applications in IaaS clouds

        Version Control Services at CERN 30m
        CERN offers three Version Control Services, one using SVN and two older services using CVS. The older CVS service is to be closed by 2Q 2011 and will be merged into the high availability CVS service on AFS where the performance has been improved to suite the needs of all users. The main SVN service has expanded a great deal, in users, commits and repositories, since it started in 2009. Our future plans include new tools for users, internal software upgrades, improved statistics and monitoring.

        The National Grid Service Cloud 30m
        The UK's National Grid Service is investigating how it can best make use of cloud technologies in the future. The focus is on users, not only those who want to perform computationally intensive research, but also others in the wider academic setting. The usefulness of Infrastructure as a Service clouds to this community is crucial in determining future cloud provision in this area. To examine this question, Eucalyptus-based clouds were deployed at the Universities of Edinburgh and Oxford to gain real experience from the users' perspective.
