SparSol is a software package intended for preconditioned iterative solution of large
sparse linear systems. It includes a number of iterative methods, preconditioners, scaling and reordering
algorithms allowing one to choose the optimal combination of algorithms for a particular problem.
The paper briefly describes the implemented algorithms and numerically compares the performance
of SparSol with that of several popular, freely available software packages using test systems arising
from hydrocarbon reservoir simulations.
The journal provides English translations of selected new original Russian papers on the theoretical aspects of numerical analysis and the application of mathematical methods to simulation and modelling. The editorial board, consisting of the most prominent Russian scientists in numerical analysis and mathematical modelling, select papers on the basis of their high scientific standard, innovative approach and topical interest.
