Robert ZIMMERMANN

Universit?t Bonn - Germany

As a PhD student at the University of Bonn I am currently working on setting up and commissioning an ATLAS Tier-3 computing cluster in the context of the LHC Computing Grid (LCG). This includes work on all required parts of such a cluster, like network infrastructure (DHCP, dDNS), base-system (SL) and middleware (gLite) installation and configuration, monitoring and the automation of all of this (Quattor). I am also one of the administrators of the local desktop (Debian) and batch (SGE) clusters for our high energy physics groups. I am familiar with various flavors of Linux like Scientific Linux, Fedora, Debian or Ubuntu, have, of course, run across MS Windows and personally enjoy using Mac OSX. Programming and scripting languages I've worked with (out of necessity or just for fun) include C, C++, Objective C, ruby, perl and bash.

Constantin Mihai CUCIUC

National Institute of Physics and Nuclear Engineering, Bucharest - Romania

I am in the 5th year of study at Informatics Physics, and I am currently involved in some detector calibration and readout system development and configuration. Also, I had to implement minor changes in some Athena analysis code and tweak the firmware for some home-brew hardware. In doing so, I came across C/C++, ROOT and LabVIEW, to which a few others learned in school or by myself can be added.

Matti KORTELAINEN

Helsinki Institute of Physics - Finland

I am a first year PhD student in experimental particle physics. My work at Helsinki Institute of Physics includes Higgs analysis in the CMS experiment and code development for test beam detector studies (Helsinki Silicon Beam Telescope, SiBT). I have wide experience and knowledge from computing and programming. I use actively Linux and Mac OS X, and I've also used commercial Unices, NetBSD and Windows. My programming skills include C, C++, Java, Matlab, Perl, Python and shell scripts. I am also familiar with assembly, Scheme and SQL. I have worked in cluster and supercomputer environments, and I have also used grids (mainly Nordugrid ARC).

Oliver OBERST

Karlsruhe Institute of Technology - Germany

I started to work as a PhD student at Karlsruhe in August 2007. The thesis will consist of two parts, a computational one and a physics analysis. At the moment a computing cluster at the Karlsruhe Institute of Technology is shared among eight different departments and will also be part of the WLCG as the UNI-KARSLRUHE Tier 3 site. To run Grid jobs on such a shared cluster the incompatibilities between the requirements in hard and software of the different user groups are resolved in using virtualization techniques to partition the computing cluster dynamically. My current task is to implement this functionality into the batch system, that it can manage the virtual machines (virtual worker nodes) to connect the cluster and its mass storage system to the WLCG.

David GONZALEZ MALINE

CERN, Geneva  - Switzerland

I studied software engineer in Spain and the UK, finishing last year a MSc in artificial intelligence. Nowadays I work at CERN in the SFT group, helping in the development of the ROOT framework. In particular, my work is focused in the development of mathematical algorithms, paying special attention to the efficiency and accuracy of the different implementations. I also work with methods of multivariate analysis and help in the development of some parts of TMVA.

Paolo TEDESCO

CERN, Geneva  - Switzerland

I am currently working at CERN, at the development of File Transfer Service, a data management grid middleware component. FTS is used by experiment frameworks to move data across sites, offering load balancing and monitoring capabilities. I have programming experience on Windows and Linux environments, mainly in C++ and c#.
