Abstract

We have developed a new mulithreaded code with pthreads for calculating longitudinal collective instabilities on computers with multiprocessors. We have selected pthreads as the basis for multiprocessing because it is portable, as such we are able to port this code to Solaris, IRIX and OS/2 platforms. We will demonstrate that when there are four cavities and 36 bunches in the simulation, our code shows a speed increase of > 3× compared to single processor code when run on a symmetric multiprocessing (smp) machine
