The calculation performance of two types of moment calculation algorithms are evaluated on a GPU system with nVIDIA C2070 board and vector-type system on the Earth Simulator for one of the particle-in-cell plasma simulations. Those are WORK and SORT algorithms. The performances are compared with the scalar system (Intel Xeon) performance. We use 8 byte double precision variables for physical memory on both CPU and GPU chips. The used simulation algorithm is three-dimensional Hybrid code for ion-ion beam instability with periodic boundary system.OS6-9; 31st JSST Annual Conference (September 27-28, 2012, Kobe University, Japan) / Authors from proceedings TO
