Abstract: In this work we present scrambled low discrepancy sequences and their application in quasi-Monte Carlo methods for solving quantum-kinetic integral equations which describe the electron transport in semiconductors. Parallel versions of this application are developed for the three target HPC platforms available to us: supercomputer Blue Gene/P, HPC cluster and GPU-enabled cluster. Numerical results for parallel efficiency and computational cost are presented. In addition we discuss the coordinated use of heterogeneous HPC resources by one application in order to achieve a good performance.
