1. The English language should be improved as it comes to style and grammar.
2. It would be great to replace the paper title with this one "Software complex for realization of mathematical models, methods and algorithms for the execution time estimation of complex tasks in multiprocessor computer systems". It is more readable for my opinion.
3. In Abstract phrase "To solve the problem of forecasting" need to be replace with this one "For solving the execution time prediction task" Because the existing phrase has a completely different meaning.
4. Unfortunately, I can't find such results in the work: " Based on the analysis of mathematical models, methods and algorithms of direct stochastic modeling and belt-based stochastic modeling, as well as studies..." Perhaps this phrase should be deleted.
5. In the conclusions written about some characteristics of the test example. However, I can't find any signs of carrying it out at work.
