Parallel Methods in Transport Theory

Transport equations are important in many different applications such as nuclear design, radiation therapy in medical science, and radiation effects in global weather models. They are also a fundamental part of many algorithms used to model more complicated applications such as shielding of the electronics satellites. New numerical methods for solving these equations are being designed. This is specially true when considering parallel architectures. Parallel algorithms are important since transport equations involve many variables, such as angle of scaterring, flux and energy and time. Standard approaches to solving transport discretizations have to be modified to get good results on high performance computers. The speakers will discuss several approaches on different computer architectures.
