Abstract
The magnetohydrodynamic equilibrium problem in magnetic confinement fusion devices is solved by using the Variational Moments Equilibrium Code (VMEC). The sequential version of the code is computationally very expensive and may take several days of CPU time. In this work we present two parallelization techniques for the code. First, an automatic tool has been used as a guidance for the parallelization of the critical parts of the code, and some deficiencies of its automatic parallelization techniques have been determined. In a second approach, these shortcomings are overcome to develop manual techniques which offer better results and can be used in future automatic parallelizers.
