14:45 Performance of Hadoop file system on a HEPiX storage workgroup testbed¶

This work is continuation of storage solution testing performed by HEPiX storage workgroup on it's testbed at FZK. Hadoop, an Apache project, offers a cluster file system called HDFS inspired by Google File System and designed to run on commodity hardware. It has gained some popularity in OSG, where is has become a supported storage solution, and is currently in production at a few T2 sites. In this series of tests we used HEPiX testbed worker nodes' hard drives as a underlying storage, without using external file servers or storage arrays. We used a standard HEPiX storage application suite to evaluate performance of this solution. We present obtained results in this paper.

15:30 Batch virtualization project at CERN¶

Between March and August 2009 a project has been set up at CERN with the aim to evaluate possibilities to use virtualization at a large scale, with the focus on batch computing. Two key issues have been identified for this specific application: the placing of virtual machines on an appropriate hyper-visor, and the selection of an appropriate image which should be driven by the actual demand. Both commercial and free software solutions exist which are able to solve the placing issue. The virtual machine orchestrater, VMO, a commercial solution by Platform computing, and the free software solution OpenNebula have been evaluated during the project. For VMO, the vendor provided a first implementation of an algorithm for selecting the image to be deployed, which is driven by user requirements of pending batch jobs. For OpenNebula, an external mechanism needs to be developed to perform this task. In the presentation, the basic concepts of the project and lessons learned will be presented. Further visions and possible implications for services offered at CERN will be described.

10:30 → 12:00 Monitoring Infrastructure and Tools I¶

10:30 Open Source Solution for Monitoring of Grid Services in WLCG¶

Since 2005 Worldwide LHC Computing Grid (WLCG) services have been monitored by the Service Availability Monitoring (SAM) system which has been the main source of information for the monthly WLCG availability and reliability calculations. During this time SAM framework gained popularity amongst site and service managers and was very useful in building robust grid infrastructure. Experience with this monitoring tool as well as preparation to the evolution of the European grid infrastructure from EGEE to national grid initiatives (NGI) led to design of the enhanced and distributed model for monitoring grid services. Nagios has been adopted as a monitoring framework and messaging technology (ActiveMq) has been chosen as a transport mechanism. This talk covers the architecture of the new system.

Speaker: Mr Wojciech Lapka (Unknown)

Slides Hepix2009_WL.pdf Hepix2009_WL.ppt

11:00 Unified Performance and Environment Monitoring using Nagios,Ganglia and Cacti¶

We will present information on how the data is collected, viewed and analyzed, with specific examples from NERSC's Cray system.

Speaker: Mr Thomas Davis (NERSC/LBNL)

11:30 Monitoring tape drives and medias at CC-IN2P3¶

Due to the continuous load and intensive usage on our robotics, we regularly face some hardware issues with tapes and tape drives. A recurrent issue concerns possible data loss which leads to go through a long recovery process. In order to improve our reliability, we have studied commercial solutions to avoid permanent write/read errors, or at least foresee occurring errors. We've tested two products (one month period each) and purchased the one that met our requirements best. In this talk I'll expose the criteria to select the product, our daily usage after 4 months of use and finally what we expect to do with/around it in the near future.

16:30 Intel HPC environment for Silicon Design and Key Learnings¶

Silicon design technical complexity is increasing every year due to several new features and process technology shrinks. Additionally, the business drivers such as shorter product development time, reduced headcount, and lower cost is increasing pre-silicon verification, high degree of design automation, and global multi-site design teams. These two factors (technological and business) are astronomically increasing demand on computing and storage driving design computing to be engineered as an HPC environment. This presentation will cover Intel HPC design compute environment, generational improvements, and realized value in the areas of compute clusters, very high large memory servers, optimal network, and parallel storage.

09:00 Web application security¶

CERN hosts a large number of Web sites (CERN-related, but also private), both on central Web Services, as well as on machines managed by particular Web site owners. Some of these Web sites are actually interactive Web applications developed with languages like PHP, ASP, Java, Perl, Python etc. - and unavoidably a fraction of them have bugs making them vulnerable to attacks such as Cross Site Scripting (XSS), Code/SQL Injection, Cross Site Request Forgery (CSRF), and so on. To address this issue, several Web application vulnerability assessment tools have been evaluated at CERN, and chosen ones are used to find vulnerabilities before the attackers do. This talk will discuss the choice of tools, the findings, and suggestions how Web application security can be improved in large organizations.

09:30 Security aspects of the WLCG infrastructure¶

The Worldwide LHC Computing Grid (WLCG) infrastructure has been built up for the storage and analysis of the very large data volumes that will be recorded by the LHC experiments. Its existing security mechanisms and policies are foreseen to evolve in various respects, for example with an increasing use of virtual machines, pilot jobs, clouds, enhancements to data storage and access models, and potential integration with single sign-on campus-wide or federated identity management systems. To steer such evolution, input from the HEPiX community would be very desirable.

The Karlsruhe Institute of Technology (KIT) was founded at 1st October 2009, merging the University of Karlsruhe and the Forschungszentrum Karlsruhe. As a first new organizational unit of the KIT the Steinbuch Centre for Computing (SCC) was established, combining the former Institute for Scientific Computing of Forschungszentrum Karlsruhe and the Computing Centre of the Technical University Karlsruhe. The KIT merge process directly influenced the SCC which has to cover two locations with a distance of 10 km. The IT service management, according to the industrial standard “IT Infrastructure Library (ITIL), was selected by the SCC as a strategic element to support the merging of the two existing computing centres. The service support processes of ITIL like: Incident, Problem, Change, Configuration and Release Management are the basis of SCC’s first class IT Services. The talk explains the different roles and tools of each ITIL support process and it puts attention to the special needs of GridKa, the German Tier-1 centre of the WLCG infrastructure, hosted at the SCC.
