This project seeks to advance the state of the art of parallel systems. Usually, the layers of a parallel system - the compiler, run-time system, operating system, and hardware - are considered as separate entities with a rigid division of labor. This project investigates an alternative model, "interweaving," in which these layers are integrated as needed to improve the performance, scalability, and efficiency of the specific parallel system. The research involves five thrusts: (1) Blending studies using compiler technology to achieve integration of code that would normally be found in distinct, separately compiled layers. (2) Coherence considers hardware without memory coherence and its implications throughout the "interwoven" parallel system. (3) Predictability studies the integration of hard real-time behavior into a parallel system through hardware and compiler support. (4) Mapping considers address translation for parallel systems given hardware and compiler support. (5) Debugging studies how to debug an interwoven system. These investigations go hand-in-hand with the continual development of a prototype and its evaluation.Parallel systems are of critical importance for science and engineering, and have become ubiquitous; even simple devices like smartphones incorporate growing parallelism. The project thus has the potential to improve a wide range of applications both through its ideas and is open code. It will also train Ph.D. and undergraduate students, and enhance collaborations between two Chicago-area universities. Code, data, and results will be maintained publicly (http://interweaving.org) for the project's duration, and requests considered for five years afterwards.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目旨在推进并行系统的最新技术水平。 通常，并行系统的各个层--编译器、运行时系统、操作系统和硬件--被认为是具有严格分工的独立实体。 这个项目研究了另一种模型，“交织”，其中这些层根据需要进行集成，以提高特定并行系统的性能，可伸缩性和效率。 本研究主要包括以下五个方面：（1）利用编译器技术进行混合研究，以实现通常在不同的、单独编译的层中发现的代码的集成。 (2)一致性考虑没有内存一致性的硬件及其在整个“交织”并行系统中的含义。 (3)可预测性研究通过硬件和编译器支持将硬实时行为集成到并行系统中。 (4)映射考虑了给定硬件和编译器支持的并行系统的地址转换。 (5)调试研究如何调试一个交织的系统。 这些研究与原型的持续开发及其评估密切相关。并行系统对于科学和工程至关重要，并且已经变得无处不在;即使是智能手机这样的简单设备也包含越来越多的并行性。 因此，该项目有可能通过其想法和开放代码来改进广泛的应用程序。 它还将培养博士。和本科生，并加强芝加哥地区两所大学之间的合作。代码、数据和结果将在项目期间公开维护（http：interweaving.org），申请将在项目结束后的五年内得到考虑。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
