In this paper we address the issue of workload decomposition in programming hierarchical distributed‐shared memory parallel systems. The workload decomposition we have devised consists of a two‐stage procedure: a higher‐level decomposition among the computational nodes; and a lower‐level one among the processors of each computational node. By focusing on porting of a case study particle‐in‐cell application, we have implemented the described work decomposition without large programming effort by using and integrating the high‐level language extensions High‐Performance Fortran and OpenMP.
