Abstract
Within the fusion community, a large number of codes are in use to simulate various aspects of the plasma behaviour. Many codes have been written by physicists with a big emphasis on the physics without using the latest technologies available in computer science. For improving this situation, a project with acronym EUFORIA was created. The main target of this project is to increase the performance of key existing codes, either parallelizing the sequential codes or improving their parallelization. However, in general these codes were not thought for new supercomputers based on muticore architectures and only take advantage of the task level parallelism, basically using Message Passing Interface (MPI). In this paper we discuss several possible ways to apply hybrid parallelization techniques in fusion codes for exploiting new multiprocessor supercomputers under development.
