System and network administration

Three administrators assure the good operation of the laboratory’s IT resources. They ensure :

  • administration and maintenance of Windows and Linux servers
  • administration of local networks (wired and wireless) and their security
  • maintenance and evolution of the Windows and Linux client base
  • management of IT orders for the laboratory (hardware and software)
  • management of installations and updates of software used for office applications, calculation and simulation (Matlab, Mathematica, etc.), data analysis (ROOT, GEANT4, etc.), electronic (Cadence) and mechanical CAD (Catia/3DExperience, SpaceClaim)…
  • management of user requests and incident follow-up
  • management of user and business documentation and the service catalogue
  • management of video conferencing systems and telephone equipment
  • help and support for users

Scientific calculation

A developer designs and produces numerical solutions dedicated to simulating and modeling physical phenomena in collaboration with research groups, such as software to produce analytical descriptions of tabulated neutron star equations of state for the LuTH-Caen VIRGO collaboration. He also ensures that numerical tools he produces are sufficiently robust and optimized for use on suitable computing architectures.

Software development

Three developers design and implement software applications dedicated to data acquisition and analysis.
The developed softwares are used for hardware setup, command and control, storage, analysis and visualisation of data, in response of:

  • instrumental needs, such as the FASTER (digital DAQ designed and built by an engineer from the Instrumentation Department) and RHB (ROOT Histogram Builder for ONLINE data analysis) projects
  • R&D needs, such as the test benches used to characterise the ASICs developed by the SEM (TEPIC, MCC2SA, DiamASIC, PLAS, etc.)
  • more specific requests such as for the « Fête de la Science » and the popularisation of science (Muoscope…)

The produced applications range from the lowest to the highest level (hardware driver, module, script, GUI) and can be deployed in different formats (executables, libraries, debian packages).

The source codes are mainly written in ADA, C/C++ and Python languages and are all centralised on local (Trac/SVN) or remote (CCIN2P3 Gitlab) repositories.

Cross-cutting activities

One sysadmin of the staff acts as Information Systems Security Correspondent for the laboratory and is also correspondent for the IN2P3 GED ATRIUM.
A developer is a member of the Steering Committee of the DevLOG network , the national network of software developers in high education and research and is also a correspondent for the RI3 network , the network of computer scientists from IN2P3 and IRFU.
