传统高性能计算系统提供了标准的预置环境来支持科学计算。然而,高性能计算的发展需要为越来越多应用提供支持,如人工智能、大数据等。标准的预设环境已无法满足这些多样化的要求。如果用户仍然在高性能计算系统上运行这些新兴应用程序,他们需要手动维护应用程序的特定依赖项(库、环境变量等),这增加了用户的开发和部署负担。此外,多用户模式也带来用户之间的隐私问题。像Docker和Singularity这样的容器可以封装作业的执行环境,但是在高度定制的高性能计算系统中,Docker和Singularity的跨环境应用部署是受限的。容器镜像的引入也给系统管理员增加了维护负担。针对上述问题,本文提出一种适用于高性能计算的自部署执行环境(SDEE)。SDEE结合了传统虚拟化和现代容器的优点,为用户提供了一个独立、可定制的环境(类似于虚拟机)。该用户是此环境中的根用户。用户开发和调试应用程序,并在此环境中部署其特殊的依赖项,然后可以通过传统高性能计算系统的作业管理系统,直接将作业加载到计算节点。作业及其依赖项将被自动分析、打包、部署和执行。该过程实现了透明、快速的作业部署,不仅减轻了用户负担,而且保护了用户隐私。实验表明,SDEE引入的开销可忽略不计,比Docker和Singularity都要低。

Finding a good solution method for topology optimization problems is always paid attention to by the research field because they are subject to the large number of the design variables and to the complexity that occurs because the objective and constraint functions are usually implicit with respect to design variables. Guide-Weight method, proposed first by Chen in 1980s, was effectively and successfully used in antenna structures’ optimization. This paper makes some improvement to it so that it possesses the characteristics of both the optimality criteria methods and the mathematical programming methods. When the Guide-Weight method is applied into topology optimization, it works very well with unified and simple form, wide availability and fast convergence. The algorithm of the Guide-Weight method and the improvement on it are described; two formulations of topology optimization solved by the Guide-Weight method combining with SIMP method are presented; subsequently, three numerical examples are provided, and comparison of the Guide-Weight method with other methods is made.
