The machine architectures used for scientific computing are ever growing in scale and complexity. Software has not been keeping up with this development, and application codes often use multiple parallelism modes and parallel programming systems (typically MPI and a co-processor or threading library) to extract all possible performance. This makes current architectures unnecessarily hard to use for any but the most experienced programmers.This project addresses parallel programming on contemporary supercomputer architectures. Based on a new theoretical model, called the Integrative Model for Parallelism (IMP), this project develops a framework for such hybrid designs. Ultimately, the goal is to develop a production software system that allows domain scientists to write applications independently of the underlying supercomputer hardware. This project creates a demonstration prototype, a `mini-application' for N-body dynamics, a simplified code containing the essential structure of the parallelism in an N-body application, to be used for the demonstration of the principles of the IMP model. This mini-app can be run, unchanged, using different types of parallelism, tailored for the underlying hardware. Having such a software system implies for application scientists both increased productivity over current approaches, and a guarantee of comparable efficiency of execution.

用于科学计算的机器架构的规模和复杂性始终在增长。软件尚未跟上此开发，并且应用程序代码通常使用多个并行模式和并行编程系统（通常是MPI和协作处理器或线程库）来提取所有可能的性能。这使得当前的体系结构不必要地用于除经验最丰富的程序员以外的任何人。该项目解决了当代超级计算机体系结构的并行编程。基于一个新的理论模型，称为并行性的综合模型（IMP），该项目为这种混合设计开发了一个框架。最终，目标是开发一个生产软件系统，该系统允许域科学家独立于基础超级计算机硬件编写应用程序。该项目为n体动力学创建了一个演示原型，一种“微型应用”，这是一种简化的代码，其中包含n体应用程序中并行性的基本结构，用于演示IMP模型的原理。可以使用针对基础硬件定制的不同类型的并行类型运行，不变，不变。拥有这样的软件系统意味着应用程序科学家既比当前方法提高生产率，又可以保证可比较的执行效率。
