  The development and the implementation of a Particle-in-Cell code written in
the Unified Parallel C (UPC) language for plasma simulations with application
to astrophysics and fusion nuclear energy machines are presented. A simple one
dimensional electrostatic Particle-in-Cell code has been developed first to
investigate the implementation details in the UPC language, and second to study
the UPC performance on parallel computers. The initial simulations of plasmas
with the UPC Particle-in-Cell code and a study of parallel speed-up of the UPC
code up to 128 cores are shown.
