Your responsibilities

The future High Energy Physics experiments are facing the need of a very high number of simulated events required to perform precise physics analysis. In order to cope with this challenge, a new generation Monte Carlo simulation toolkit is being developed.

Your task will be to play the key role in the development of this novel code, using state-of-the-art C++ programming techniques, taking advantage of the modern computing hardware, like GPUs, with new algorithmic approaches based on parallelism.

You will work on the implementation of the geometry model for the GPUs, development and optimization of the parallelized workflow and physics models for the GPU, as well as the integration of the GPU simulation with the current state-of-the art Geant4-based simulation applications.

You will also work closely with the LHC experiments to gather and understand their requirements for the simulation and to assist them in the integration of the prototype into their software frameworks.

About us

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's 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 http://home.cern.
