Jeroen Bédorf – Leiden Observatory
He is a PhD student at the Leiden Observatory in the Netherlands. He obtained his Master of Science in Grid Computing at the University of Amsterdam. The topic of the thesis was high performance N-body simulations using Graphics Processing Units. After his master he started as a Ph.D. to continue the work on high performance N-body codes and applying them to problems in computational astrophysics. The N-body codes are accelerated using GPUs. He has developed multiple N-body codes either using direct N-body or using hierarchical tree-code algorithms (for example the Bonsai tree-code). These tree-code methods are used to simulate the formation of galaxies and the effect galaxy mergers have on their evolution. His current research interest is on optimizing these simulation codes for large scale parallel GPU systems and thereby making optimal use of the GPUs and CPUs.
