Abstract
The article is devoted to the development of automated debugging software for parallel programs used in the analysis of the impact of mining on the ecology of the region using the MPI communication interface. The system combines the approaches of static analysis of the source code and automated control of correctness at runtime. Each approach implements a separate component of the system. An innovative idea embedded in the system is to determine the necessary checks in the patterns of erroneous behavior that the user can control by modifying the templates from the proposed set, adding their own or deleting ones that are not required. A system for describing patterns is described and several examples of formalizing errors are given. Some of the examples of errors are suitable for static analysis, while others are suitable for automated verification. The architecture and the general scheme of the automated debugging system on a computing cluster are presented. Another software project described in the article is an engineering computing portal. The portal is an expandable environment for a comprehensive study of the environmental problems of the region, integrating various services united by high-performance computing.
Highlights
In the modern scientific world, the accuracy of numerical models of the studied objects and phenomena continues to increase, which causes an avalanche-like increase in computations in HPC problems.The creation of an information portal that combines information on mining and their further use into a single model is extremely important for the Kuzbass
On the head node, the source code of the user program is processed by the preprocessor, which is the first component of the system
From the presented set of templates, he selects suitable for static analysis, which is determined by the number of processes installed in the unit, and the presence in the template text of certain keywords, which include, in particular, pseudofunction "SIZE"
Summary
In the modern scientific world, the accuracy of numerical models of the studied objects and phenomena continues to increase, which causes an avalanche-like increase in computations in HPC problems.The creation of an information portal that combines information on mining and their further use into a single model is extremely important for the Kuzbass. This information comes from each mine, mine, processing plant, metallurgical and chemical plant. The analysis of this information will allow creating a computer model of the environmental impact of the entire industrial complex of Kuzbass, identifying the most dangerous sources of pollution and putting together administrative, economic and engineering environmental protection measures
