Job Description
Your responsibilities
The LHCb experiment at the LHC focuses on exploring the minute difference between matter and antimatter and searching for new physics. Its simulation software is continually evolving to meet demands of more accurate and largerscale Monte Carlo samples essential for physics analysis and future detector upgrades studies.
A new version of the Gauss simulation framework based on Gaussino is replacing the existing system. Gaussino integrates Gaudi HEP generators and Geant4. Work is underway to incorporate Machine Learning (ML) and GPU acceleration to enhance computational performance. Gaussino is experimentindependent and provides the basic structure for any experiment simulation while Gauss extends it to meet the LHCb specific needs.
As part of the LHCb Detector Group (LBD) within the Experimental Physics Department (EP) you will contribute to explore new approaches in the LHCb simulation software. You will participate to the development and maintenance of the code to ensure its consistency and reliability for production in a flexible manner including in a future heterogeneous computing environment.
Key responsibilities :
- Contribute and take responsibility for some of the development of the Gaussino and Gauss frameworks e.g. multithreading options for different simulation use cases integration of ML and/or GPU in the generators or detector modelling
- Explore and implement new techniques within the Gauss framework and their use in a distributed heterogeneous production environment.
- Take responsibility for a new easytouse and flexible infrastructure for configuring Gauss and Gaussino.
- Contribute to the ongoing support and maintenance of Gauss and Gaussino.
Your profile
Skills
- Knowledge of HEP simulation aspects i.e. generators detector geometry Geant4 etc.

About us
At CERN the European Organization for Nuclear Research physicists and engineers are probing the fundamental structure of the universe. Using the worlds largest and most complex scientific instruments they study the basic constituents of matter fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact and provides insights into the fundamental laws of nature. Find out more on .
