摘要：

This paper deals with development of algorithms and tools for accurate matrix computations based on combinations of multi-precision arithmetic with dynamically changed length of operands and parallel distributed MIMD-system using Message Passing Interface (MPI) for communications. The influence is analysed of rounding errors in basic distributed matrix operations. The portable library based on accurate distributed vector/matrix operations is described, as well as results of its testing are presented.
