In this effort research and education at the boundary of parallel systems and applications will be performed. It is motivated by the need for application insights to make fundamental advances in parallel systems, and the recent convergence in multiprocessor architectures to general purpose nodes connected by a communication architecture. On the research side, challenging, irregular, dynamic applications will be parallelized on real systems in close collaboration with domain researchers, particularly in probabilistic protein structure determination and adaptive unstructured meshing, and their implications for parallel architecture and software understood. General techniques for partitioning such complex applications will be developed, particularly for the emerging class of cache- coherent distributed-memory multiprocessors. The applications will be distributed as benchmarks to the parallel computing community. Architectural implications, particularly communication demands, scaling and resource distribution, will be examined, and scaling methodologies developed. Funds permitting, a range of commercial systems will be evaluated using applications, to understand the impact of their communication architectures and tradeoffs, and insights into programming and performance debugging environments studied. On the education side, a new undergraduate course in parallel architecture will be developed, and a textbook on parallel architecture is being written to articulate the convergence and develop parallel architecture as an engineering rather than exotic discipline.

在这项工作中，将进行并行系统和应用程序边界的研究和教育。它的动机是需要应用的见解，使并行系统的根本性进展，以及最近的收敛，在多处理器架构的通用节点连接的通信架构。在研究方面，具有挑战性的，不规则的，动态的应用程序将在真实的系统上并行化，与领域研究人员密切合作，特别是在概率蛋白质结构确定和自适应非结构化网格，以及它们对并行架构和软件的影响。将开发用于划分这种复杂应用程序的一般技术，特别是用于新兴的高速缓存一致性分布式存储器多处理器。 这些应用程序将作为基准分发给并行计算社区。 建筑的影响，特别是通信需求，缩放和资源分配，将被检查，并扩展方法的发展。在资金允许的情况下，将使用应用程序对一系列商业系统进行评估，以了解其通信架构和权衡的影响，并深入研究编程和性能调试环境。在教育方面，将编制一个新的并行架构本科课程，并正在编写一本关于并行架构的教科书，以阐明这种趋同，并将并行架构发展为一门工程学科，而不是一门外来学科。
