        A scheme for defining and deploying trusted Virtual Machines to Grid Sites using Configuration Management Systems 30m
        Sites (service providers) and VOs (service users/functionality providers) are debating how to define trusted VO-provided VM images. We present an alternative scheme that, using a Configuration Management System (CMS), does not require Sites to trust VO-provided images. It gives VO the freedom to design and customize functionalities, while letting Sites retain full control over instances. Configuration Management Systems (CMS, such as Puppet/Cfengine, have been widely used in computing centers to automatically manage resources. They provide high level languages to define desired states of target systems, such as installing software packages, running services, enforcing firewall, etc. We propose a two level scheme. Both VO and Site start from a well trusted base image (e.g. base installation of SL5 with no customization). At the VO-level, VO experts customize the base image to perform VO specific tasks (e.g. ATLAS Condor Worker). These customizations are not committed to the image, instead, they are defined in CMS language and stored in a SVN repository. At the Site-level, site experts define site-specific configurations and security policies in CMS language. When deploying, VO needs no privileged access in instances. Site manager starts the base-images that contains CMS clients, which apply VO-level definitions then Site-level definitions. At this time, the instance is ready to perform VO defined tasks. Since Site-level definitions are applied at last, the VMs are ensured to comply with Site policies. This scheme eliminates the problem of trusting VM images. It is more flexible, more reliable, and more secure.

        CERNs image distribution system for the internal cloud 30m
        In any large-scale virtualized environment, the image distribution system plays a central role. It is must not only deliver up-to-date images to the hypervisor with appropriate performances, but it should also establish and maintain a sufficient level of trust in the actual images that are being distributed. These issues can be addressed by using a peer-to-peer-based image distribution system, depending on a trusted and signed index providing an up-to-date list of images that hypervisors can trust. This presentation describes the technologies used to establish such an infrastructure at CERN, the challenges encountered in their deployment and in their integration in a production environment, as well as the future developments, in particular to enable virtual image sharing with other sites.

        ASSETS at LEPP - our FLOSS Inventory and Monitoring server 30m
        Inventory and monitoring are two areas that have become more important at LEPP over the last few years in the IT area. We've had increased requirements to track what computers we buy, who gets them "out of stock" and various status changes, from location changes through to disposal. Knowing where a computer is located is only part of the battle. Important servers and systems must be tracked as to whether they are available, are necessary services running and what remediation is necessary in down events. LEPP has implemented a Scientific Linux 5 x64 server running three FLOSS products to manage our needs in these areas. Automatic Inventory is achieved on Windows and Linux nodes via OCSNG and some software deployments are also managed via that tool. GLPI imports the automatically gathered data for additional manual inventory information such as ownership, stock management, ongoing historical notes etc... Zenoss provides continuous monitoring and performance graphing for our important infrastructure. Events are stored locally for reference, and alerts are generated for specific events of interest and delivered via e-mail.

        NERSC/PDSF Status report - A Year of Changes 10m
        PDSF is a networked, distributed computing environment used to meet the detector, simulation, and data analysis requirements of physics (large-scale, high-energy physics, and astrophysics) and nuclear science investigations. Since our last report two years ago, the cluster has been upgraded significantly. We retired older nodes, expanded compute and storage capacities, and fortified network connectivity. While eight-core AMD compute nodes were retained, older nodes were replaced dual quadcore- (Intel Nehalem) and dual hexcore- (Intel Westmere) based Dell PowerEdge R410 systems. Total cluster capacity also grew by 50 percent, from 800 to 1200 job slots. Total storage capacity has been expanded to about 1TB (comprised of a combination of GPFS and xRootd file systems deployed atop mostly Dell SAS-based units. Networking infrastructure, although still 1 GigE-based, has been fortified with new switches (which couple the PDSF cluster to ESnet at 10 Gbps) and additional data transfer nodes with 10GigE network connectivity.

        New network architecture at IN2P3-CC 30m
        The Computer Centre of the French National Institute for nuclear and particle physics (IN2P3-CC), located in Lyon, has recently rolled out a major network upgrade. The previous network architecture, nearly 4 years old, reached limits and an upgrade was necessary to face new challenges, particularly massive data transfers, virtualisation, heavy Grid computation and an upcoming additional computing room. After a thorough analysis of current network devices (feature, topology, configuration, usage) and network behaviour (identifying traffic patterns, main areas of exchange, bottlenecks, major consumers and producers) a new architecture was designed. A key objective, besides removing bottlenecks, was to improve scalability of the network, especially by enabling seamless and non disruptive bandwidth upgrades in the future. Strong attention was paid to use configurations able to deliver wire speed. Even with strong preliminary testing and anticipating all possible tasks (pre-wiring, creating new configurations, making checklists...) the deployment was done in September 2010 within a nightly scheduled maintenance during a 5 hours network intervention (not continuously service impacting). We also used the maintenance window to upgrade software on 170 network devices, harmonising management and supported features. Layout was completely re-organised to reduce as much as possible paths length for heavy exchanges. The new network architecture is built around a central redundant Cisco Nexus 7018 aggregating flows up to 60G from several key functional areas (storage, computing, WAN...). Hosts doing intensive exchanges are connected up to 10G directly through a distribution layer, mainly featuring 4900M and Catalyst 6500, while other consumers are offloaded onto an access layer. 80G are foreseen to connect the new computing room.

        In the recent years, High Energy Physics sites have significantly improved their collaboration and are providing services to users from a growing number of locations. The resulting attack surface, along with the increased sophistication of the attacks, has been a decisive change to encourage all the involved security teams to cooperate very closely together. News challenges in the security area have also appeared, including a more noticeable interest from the press in security incident handing. This presentation provides an outlook of these evolutions, along with several upcoming challenges and security risks that the community will need to deal with.

        Access Grid via Web 30m
        L-GRID is a light portal to access Grid infrastructure via Web browser, allowing users to submit their jobs in a few minutes, without any knowledge about the Grid infrastructure. The portal is intended to be a helpful tool to access Grid resources shared all around the world via a simple Web interface, using whatever operating system and browser. It provides the control over the complete lifecycle of a Grid Job, from its submission and status monitoring, to the output retrieval. The end user needs only her/his own X.509 personal certificate, issued from a Certification Authority. The system, implemented as client-server architecture, is based on the gLite Grid middleware. The client side application is based on a java applet, running both on Windows, Linux and Mac operating systems; it only needs a Web browser connected to the Internet. The server relies on a gLite User Interface with Web portal provided by an Apache/Tomcat server. The main differences with respect to a native gLite User Interface are the extreme ease of use and the no-need of the user registration. L-GRID provides the typical operations involved in a Grid environment: certificate conversion, job submission, job status monitoring, and output retrieval. It provides also a JDL editor. The system is user-friendly, secure (it uses SSL protocol, mechanism for dynamic delegation and identity creation in public key infrastructures), highly customizable, open source, and easy to install - the installation requires a few MB. The X.509 personal certificate does not get out from the local machine, strictly compliant to the Certification Authority policies, and the Grid commands are splitted into client and server, increasing the security level. An extra security improvement has been achieved by the inclusion of the MyProxy server, responsible for the dynamic delegation in long term proxy certificates, on the server side portal. It allows to reduce the time spent for the job submission, granting at the same time a higher efficiency and a better security level in proxy delegation and management. The first running prototype is hosted at the moment at the High Performance Computing Center of the Scuola Normale Superiore, Pisa, Italy. The results obtained encourage future developments. Further steps are represented by the integration with a LDAP Kerberos AAI Authentication Authorization Infrastructure, and the customization for LHC and Theophys Virtual Organizations.

        VOMS/VOMRS Convergence 30m
        The Grid community uses two well-established registration services, which allow users to be authenticated under the auspices of Virtual Organizations (VOs). The Virtual Organization Membership Service (VOMS), developed in the context of the Enabling Grid for E-sciencE (EGEE) project, is an Attribute Authority service that issues attributes expressing membership information of a subject within a VO. VOMS allows to partition users in groups, assign them roles and free-form attributes which are then used to drive authorization decisions. The VOMS administrative application, VOMS-Admin, manages and populates the VOMS database with membership information. The Virtual Organization Management Registration Service (VOMRS), developed at Fermilab, extends the basic registration and management functionalities present in VOMS-Admin. It implements a registration workflow that requires VO usage policy acceptance and membership approval by administrators. VOMRS supports management of multiple grid certificates, and handling users' request for group and role assignments, and membership status. VOMRS is capable of interfacing to local systems with personnel information (e.g. the CERN Human Resource Database) and of pulling relevant member information from them. VOMRS synchronizes the relevant subset of information with VOMS. The recent development of new features in VOMS-Admin raises the possibility of rationalizing the support and converging on a single solution by continuing and extending existing collaborations between EGEE and OSG. Such strategy is supported by WLCG, OSG, US CMS, US Atlas, and other stakeholders worldwide. In this presentation, we will give an update on the status of the convergence between the two products.

        CloudCRV - Cluster Deployment and Configuration Automation on the Cloud 20m
        With the development of virtualization technology and IaaS cloud, it is much easier for users to obtain large number of computing (virtual) resource. However, customizing these resources as a computing clusters remains a difficult task that requires in-depth IT knowledge and complex user-specific customizations. We develop a tool called CloudCRV (Cloud-Cluster-Role-VMs) to help users design, distribute and deploy a secure, functional cluster on the allocated resources. We believe a predefined cluster in a whole can be distributed as a product to perform certain task (e.g. an ATLAS Tier3 cluster), we call this kind of product a Virtual Cluster Appliance (As extension to Virtual Appliance). The purpose of CloudCRV is to help the Cluster Designer to design such a product and to help the Cluster Managers to deploy it. Most clusters can be abstracted to a set of Roles (e.g. a NFS server, or a Condor Head) and their relations (Condor Head depends on NFS server). Cluster Designer's work is to define the Roles and their relations. The Roles are defined with the help of configuration management systems such as Puppet or Cfengine. Once designed, the Virtual Cluster Appliance can be deployed at multiple sites by local Cluster Managers onto physical or virtual resources. CloudCRV provide interfaces to both Cloud Providers (such as EC2 and Nimbus), and to physical computers and libvirt based clusters via gPXE remote booting and image deployment. In this contribution we demonstrates the process of designing and deploying such a Virtual Cluster Appliance with the help of CloudCRV.

        Lessons learnt from Large LSF scalability tests 30m
        During summer 2010, a large LSF test cluster infrastructure was put in place to allow scalability tests of the batch software (LSF) at a scale which exceeds the production instance by up to a factor 5. The response time of several central commands was measured as a function of the number of worker nodes and the number of batch nodes in the farm. Several issues which were found during the tests were fixed on the fly by the vendor. This way, it was possible to go up to 15,000 virtual worker nodes, and more than 400,000 jobs in the system. Some results from these scalability tests will be presented, lessons learned during the tests, and possible consequences for planning will be discussed.

        Rapid web application design for silicon detector measurements 30m
        Developments of new silicon detectors come with a demand for comprehensive measurements of its characteristics. To allow access to the measured (and processed) data by all interested parties a central data repository combined with an adequate remote query mechanism is necessary. The talk will demonstrate how the development of a web application for this purpose can be achieved with minimal resources. By using the Open Source web framework Catalyst and a SQL database a very flexible and modular design of the entire system has been achieved. Changing requirements to the system such as DB schema changes are easy to handle. The framework is rather generic and has also successfully tested for other applications.

        The CERN internal cloud infrastructure: a status report 30m
        CERNs virtualization plans have been presented during the last HEPiX meetings. Since the last HEPiX meeting, the ideas have materialized in a prototype which was used to perform large scale scalability tests of the batch system LSF. This presentation will give an overview over the architecture of the new infrastructure, and report on the experiences and lessons we learned when growing the system up to 500 machines and 15,000 virtual machine slots. It is planned to release this infrastructure into production, with the batch service being the first and initially only user. Production deployment at a small scale is planned for the second half of November, and an outlook on possible future extensions will be given.

        StratusLab, mixing grid and clouds 30m
        StratusLab (StratusLab.eu) is a two-year European FP7 project (from 1 June 2010) that aims to provide a production-quality, open source cloud (“Infrastructure as a Service” or IaaS) distribution. StratusLab will integrate, distribute, and maintain this cloud distribution to bring cloud technology to end-users and resource providers of existing distributed computing infrastructures like EGI. The StratusLab toolkit combines existing, cutting-edge, open source software with innovative service and cloud management technologies developed within the project. The project uses agile software development practices to ensure rapid evolution of the toolkit to meet end-user and system administrator needs. It demonstrates the production quality of the toolkit by running two grid resource centers on top of the toolkit and by quantitatively testing the performance of a spectrum of representative applications on the hybrid infrastructure. Grid and cloud technologies complement one another. Existing grid middleware would continue to provide the glue to federate the distributed resources and the services for high-level job and data management. StratusLab will help to improve usability of distributed computing infrastructures. Providing a cloud API for the grid will attract the scientific and industrial users that have embraced the cloud computing provisioning model and thus expand the scope and interest of infrastructures like EGI. This talk will detail StratusLab’s goals and present its two-year roadmap. It will explain the expected benefits for the e-Infrastructure ecosystem and the availability and current features of the StratusLab toolkit.

        Magellan at NERSC: A Testbed to Explore Cloud Computing for Science 30m
        Cloud computing is gaining a foothold in the business world, but can clouds meet the specialized needs of scientists? That is the question NERSC’s Magellan cloud computing test bed is exploring. Funded by the American Recovery and Reinvestment Act (Recovery Act) through the U.S. Department of Energy (DOE), the system is distributed between DOE centers: the National Energy Research Scientific Computing Center (NERSC) in California and the Argonne Leadership Computing Facility (ALCF) in Illinois. Research efforts range from evaluating what applications work well on today's commercial cloud offerings to studying how jobs can be distributed across multiple DOE clouds and exploring emerging programming models like MapReduce. We will provide an overview of the project and present some of our findings to date. This includes recent results of the performance of scientific applications running on commercial cloud offerings compared with traditional systems.
