• A three dimensional magneto-inductive gyrokinetic particle code with δf method, GYR3D, is ported to a massively parallel computer, Intel Paragon XP/S15-256, which has 256 scalar processors (nodes) connected with a two-dimensional mesh topology. The Fortran77 compiler with message-passing subroutines is used. It is found that the speed of the parallelized code scales well with the number of nodes. The speed of the parallelized GYR3D on Intel Paragon with 256 nodes is more than three times faster than that of the vectorized GYR3D on NEC SX-3/24R (vector/parallel computer) when one node is used. The parallelized GYR3D code is used to simulate the m=1 (poloidal mode number) and n=1 (toroidal mode number) kinetic internal kink mode in a tokamak. The results for the convergence study of δf code in the limit of extremely large number of particles are shown.
