从物理建模和计算机科学的角度来看，使用最先进的计算机进行先进飞机的现实多学科设计优化（MDO）是一个极具挑战性的问题。为了进行有效的飞机设计，必须在各种物理设计变量之间进行许多折衷。类似地，为了产生有效的设计方案，必须在各种MDO实现选项之间进行许多权衡。在本文中，我们研究的矢量化和粗粒度的并行化的SD计算的影响，从跨音速运输机设计问题的一个代表性的例子。
Realistic multidisciplinary design optimization (MDO) of advanced aircraft using state-of-the-art computers is an extremely challenging problem from both the physical modelling and computer science points of view. In order to produce an efficient aircraft design, many trade-offs must be made among the various physical design variables. Similarly, in order to produce an efficient design scheme, many trade-offs must be made among the various MDO implementation options. In this paper, we examine the effects of vectorization and coarse-grained parallelization on the SD calculation using a representative example taken from a transonic transport design problem.
