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

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, charge density, ion extraction current, etc. calculations. Parallelisation was done using widely accepted MPI platform. Additionally, the code has been rewritten and optimised in order to achieve better efficiency. The strongand soft-scaling properties of the parallel code are shown (tests were done using SMP machine), as well as some results of physical meaning. The code in its present form allows calculation involving 5 10 pseudo-ions at reasonable wall-clock time (circa 15 hours), which opens the gate for realistic physical conditions plasma calculations.
