A fully-global linear gyrokinetic simulation code (GYGLES) is presented aimed at describing the unstable spectrum of the ion-temperature-gradient modes in totoidal geometry. The Particle-In-Cell method is formulated with finite elements defined in magnetic coordinates, which provides excellent numerical convergence properties. The poloidal mode structure corresponding to k(11) = 0 is extracted without approximation from the equations, which reduces drastically the numerical resolution needed. The code can simulate routinely modes with both very long and very short toroidal wavelengths, can treat realistic magnetohydrodynamic, (MHD) equilibria of any size, and runs on a massively parallel computer.
