The main mission of the Computer Science and Services Laboratory (LIS) is to provide IT support for users throughout the Institute, as well as the resources needed for both day-to-day work and experimental calculations.
The LIS also manages the Institute’s purchasing and provides services, expertise and advice related to the purchasing function (Agora).
The LIS has a staff of 20, including 15 engineers and 2 apprentices. In collaboration with the CEA’s IT Department and partner institutes (CERN, CNRS, Université Paris/Saclay, etc.), the LIS defines the short and medium-term orientations of Irfu’s IT. Together with users, it defines and selects the resources to be deployed.
LIS carries out the following missions for Irfu:
User support (1000 people)
Administration of workstations (1,200 Windows, Mac and Linux computers) and servers (Windows and Linux)
Purchase of all software and hardware in accordance with CEA regulations
Definition, configuration and management of local infrastructure: machine rooms (31 bays, 600 A, 500 kW cooling), networks, backup robot (500 slots).
Definition, configuration and management of Linux-based clusters (HPC/Farms), in particular
- Alfven HPC cluster (2400 cores, 12TB RAM, 1Pb storage)
- Anais visualization cluster: 2 NVIDIA Quadro M600, 128 cores, RAM 2TB, storage 400TB,
- ISIPIC HPC cluster (256 cores, 50TB)
- An Iclust interactive and computational cluster(500 cores, 500 TB) for particle physics in particular.
- A virtualization cluster (600 cores, 1.5 TB Ram, 2.5 Po)
Management of a Tier 2 computing and storage site for the WLCG grid, GRIF (Grille au service de la Recherche en Ile-de-France), comprising over 450 machines and more than 4PiB of storage. Irfu accounts for 40% of GRIF and 11% of French computing.
Contract management and monitoring of use by IRFU staff of the IN2P3 computing center in Lyon.
Security compliance in accordance with CEA directives
Active participation in CEA bodies (DSI/USCI/DRF, etc.)
