SPARTH: super-precision parallel arithmetic processor with dynamic changing of the operand length A. Vazhenin Department of Software of High-Performance Computing Systems, Computing Center, Siberian Division of the Russian Academy of Sciences, Novosibirsk, Lavrentiev ave., 6, 630090, Russia ABSTRACT An efficient way to achieve the high accuracy of the results of computa- tions is to increase the operands capacity. The best results in terms of the problem solution rate and effectiveness of memory using can be reached in the case when a computer system provides the possibility of dynamic ca- pacity control and parallel data processing. The suggested programming system presents an effective tool for Super-precision Parallel ARiTHmetic computations (SPARTH-computations). It is developed for a STARAN-like computing system and oriented to solve a large set of vector and matrix op- erations. From the user's viewpoint the system represents a parallel vector processor wi
