Simulations of plasma microinstabilities and related turbulence are a necessary complement to stellarator experiments as e.g. Wendelstein 7-X. Especially important are full torus simulations for three-dimensional stellarator configurations. Gyrokinetics as a first principle based theory is well suited to describe the relevant physics. An established and flexible method for solving the gyrokinetic system of equations is the simulation via the particle-in-cell (PIC) Monte-Carlo method. For this purpose the EUTERPE code has been established which originally solved the electrostatic gyrokinetic equation globally in arbitrary stellarator geometry. With the availability of up-to-date high performance computing hardware it is possible to further enhanced the physical model in two aspects. The full kinetic treatment of the electrons will include trapped particle effects and the inclusion of electromagnetic effects will extend the scope of applicability to the magnetohydrodynamic (MHD) regime. These developments will make EUTERPE the first code worldwide that is able to simulate global gyrokinetic electromagnetic instabilities in three dimensions.
