An MPI-based parallel code for high performance 3-D particle-in-cell ion source plasma simulation

Marcin Turek, Marcin Brzuszek, Juliusz Sielanko


The paper presents parallel version of TRQR code, intended for ion source plasma simulation.The code is written using particle decomposition approach, and enables plasma potential, chargedensity, ion extraction current, etc. calculations. Parallelisation was done using widely acceptedMPI platform. Additionally, the code has been rewritten and optimised in order to achieve betterefficiency. The strong- and soft-scaling properties of the parallel code are shown (tests were doneusing SMP machine), as well as some results of physical meaning. The code in its present formallows calculation involving 5⋅108 pseudo-ions at reasonable wall-clock time (circa 15 hours),which opens the gate for realistic physical conditions plasma calculations.
