   Our aim is to determine effective (homogenized) material properties from tests on small material samples with relatively complicated inner structure. Such testing means solution of boundary value problems on test domains involving the microstructure with loading provided by suitable boundary conditions. This leads to the solution of high resolution FE systems. In our case, we investigate geomaterials, which are handled by X-ray CT scanning of small rock samples. Those scans provide 3D information on the structure of the samples. Material properties of the individualmaterial constituents are additional input. For the FE solution of the high resolution boundary value problems of tens or hundreds million degrees of freedom we make use of parallel computers at the Institute of Geonics and the IT4Innovations supercomputer centre in Ostrava.
   We describe efficiency of the in-house GEM solvers exploiting the Schwarz domain decomposition method with aggregation by performing computational experiments on the computing platforms above. Efficient solution of these systems is necessary for successful solution of inverse material identification problems.
