AB - <p style="text-align: justify;">This article deals with parallel iterative algorithms for linear systems with
block-band matrices. The algorithms can be used in mathematical modeling of the problems involving finite difference and finite element methods. The solvers are adjusted to
the problem and to the computing systems, which use special precompilers. Applications of the algorithms to the ACELAN-COMPOS software package focused on the new
material modeling, is described. To achieve a high performance, both parallel programming techniques and the optimization of the processor memory hierarchy are used. The
results of numerical experiments confirm the efficiency of the methods and algorithms.</p>
