Abstract. The development of the algebra-algorithmic methodology and tools for automated design and generation of programs for graphics processor units is proposed. A particular feature of the proposed approach is the use of high-level specifications that are close to natural language and application of the method that ensures the syntactical regularity of the algorithms and programs being designed. The approach was implemented in the toolkit for interactive design of algorithm schemes and generation of programs. The use of the toolkit is illustrated on the development of a parallel program in meteorology.

Keywords: algebra of algorithms, automated program design and generation, graphics processing unit (GPU), parallel programming, algorithm scheme.
