Templet development tools: The tools for application development considered in the article include parallel programming libraries, a task running and monitoring service and the monitoring subsystem for SSAU cluster. Classification of task management systems: The systems are classified by means of computing process organization and the layer of hardware abstraction. The article describes application development specifics in the field of science-oriented computing and highlights individual issues in the development of such software. Most of them are focused on the process of writing software code, but often there is a need for applications that organize the computation process and support team development. Rationale: Many different tools exist for development of scientific computing applications. The results show that the proposed algorithm provides a balance of improved robustness and speed. The proposed algorithm is implemented using OpenMDAO, NASA’s open-source framework for multidisciplinary analysis and optimization, and is tested using OpenAeroStruct, an open-source low-fidelity tool for aerostructural optimization. This paper compares these approaches and provides an algorithm that can be used to automatically select and switch between them. However, there is a lack of criteria to govern how to select between these approaches, and when to switch between them in a hybrid approach. Additionally, these two major approaches have many variations, including hybrid approaches where the MDA begins with a fixed-point iteration and then switches to a coupled-Newton approach after a certain number of iterations. On the other hand, coupled-Newton approaches have superior convergence orders, but generally require more effort to implement and have more expensive iterations. Fixed-point-iteration approaches are easier to implement, but can require a large number of iterations or diverge for strongly coupled problems. There are two major types of approaches that are used for the multidisciplinary analysis (MDA) of coupled systems: fixed-point-iteration-based approaches and coupled Newton-based approaches. ![]()
