**Abstract.**
The paper presents the results of parallel computing on GPUs for the solving
of the problem of charge transport in semiconductor devices taking into account
the radiation effect. By the example of quasi-hydrodynamic model, the reduction
of partial differential equations to the differential-algebraic problem and
numerical methods for solving it are consistently considered. The efficiency of
the considered algorithms is shown by the example of the the test problem
solution.

**Key words:**
physical and topological modeling of semiconductor devices, quasi-hydrodynamic
approximation, parallel computing on graphics processors, numerical solution of
differential-algebraic equations, modeling of radiation effects on
semiconductor devices.
