Optimization of the Particle-In-Cell method for general-purpose computers

Presented in this paper are the software techniques to improve the performance of the Particle-in-Cell method for general-purpose computers equipped with processors like Intel Xeon/Nehalem or AMD Phenom. The software techniques include particle storing in cells in either fixed size array or list, field values kept together in one array. One must note that since these techniques depend on the method only, they are suitable for virtually all computer architectures.
