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.
Would you like to coordinate the operation of a heterogeneous computing farm (CPU+GPU) designed to reconstruct collision events at the Large Hadron Collider synchronous with data taking? Are you an expert in GPU architectures and parallel programming who enjoys supporting developers in their programming and optimisation tasks? Then join the ALICE Experiment and contribute to the success of data taking with the experiments new common online/offline system called O2.
ALICE (A Large Ion Collider Experiment, http://aliceinfo.cern.ch) is a dedicated heavy ion experiment at the Large Hadron Collider (LHC). The ALICE Collaboration is studying the physics of strongly interacting matter at extreme energy densities and temperatures. In Run 3+4 (2022-2029) ALICE will operate at a peak Pb-Pb collision rate of 50 kHz. All events will be read out, reconstructed synchronously with data-taking with the essential support from GPUs, compressed and written to permanent storage without any selective trigger. This will allow ALICE to assess rare probes with large backgrounds, for which data reduction with online triggers is not possible.
Within the ALICE Physics and Computing group (EP-AIP), you will play a leading role in the operation of the ALICE O2 Event Processing Nodes (EPNs) and support activities associated with the development of efficient code for hardware accelerated platforms. Your functions will include:
Master's degree or PhD or equivalent relevant experience in the field of computing or physics or a related field.
Spoken and written English or French: ability to understand and speak the other language in professional contexts. Ability to draw-up technical specifications and/or scientific reports and to make oral presentations in at least one of the two languages.
