James Amundson, PhD

Computational Physicist


I work at the intersection of computing and physics. My background is in theoretical physics, with a Ph. D. in particle theory from the University of Chicago. I now work in scientific computing at Fermilab, where I head the Scientific Computing Division's Scientific Software Infrastructure department, managing a group of 18 developers and scientists. My technical work is in high performance computing and computational accelerator physics. I specialize in emerging technologies and massively parallel computations on supercomputers.

Although my current focus is on computing, I have unique experience in physics, having worked on all aspects of particle physics, including accelerators, experiments and theory.


I am the head of the Synergia project. Synergia is an accelerator simulation framework for emphasizing collective effects. It is a hybrid C++/Python system that scales from laptops to 100,000+ core supercomputers.

Projects in my department

My department is responsible for CMSSW, the C++ software framework for the CMS experiment at the world's largest particle accelerator, the Large Hadron Collider (LHC). CMSSW has processed roughly <\it an exabyte> of data since the start of the LHC operational runs in 2009.
My department is also responsible for art, the C++ software framework used by almost all new experiments at Fermilab.
Finally, my department is responsible for LArSoft, a collaborative project for simulation, reconstruction and analysis of data from liquid argon particle detectors. LArSoft builds upon the art framework.
