TOOL SYSTEM FOR SCALABLE PARALLEL PROGRAMS OF NUMERICAL CALCULATIONS DESIGN
Konstantin Isupov, Vladimir Knyazkov
68
Many applied problems of high dimensionality require performing of high-precision numerical calculations in
the matrix algebra basis over a field of large numbers. Modern multiprocessor computer systems typically have 32 - or 64-bit architecture, which makes it difficult to perform operations on large numbers, and reduces the efficiency of these systems. A new method was proposed for performing calculations based on using the number system with parallel architecture as a basis for implementation of numerical calculations - a system of residual classes. Tool system is developed based on this method.
FINITE AUTOMATA VALIDATION WITH VARIABLES IN FUNCTIONAL PROGRAMMING LANGUAGES
Georgiy Korneev, Yan Malakhovski
73
This article describes a domain-specific language (eDSL) for automata-based programming embedded into the Haskell programming language. Proposed eDSL supports extensive code reuse and validation of state-transition functions. This is achieved through developed representation of logical formula that is free from both fixed set of input variables and fixed set of predicates. This allows combination of states in automata even if they were designed for different sets of input variables.
