The multiprecision arithmetic allows to reduce significantly the influence of rounding errors in cases when the standard data representation does not support the required accuracy. In this paper we discuss the technology of effective programming supporting the given accuracy of calculations in the suitable time by complex using the multiprecision arithmetic, dynamically changed length of operands, and parallel data processing. The distinguishing feature of proposed approach is that the initial high parallel algorithm can be adapted to the computations with the variable capacity of data. The library is described supporting this technology on parallel computers with message passing interface for communications. Some examples are presented of solution of typical problems.
