PECASE: Applications-driven Research in Multiprocessor Architecture and Software Systems

在这项工作中，将在并行系统和应用程序的边界进行研究和教育。它的动机是需要应用洞察力来在并行系统中取得根本进展，以及最近多处理器体系结构向通过通信体系结构连接的通用节点的融合。在研究方面，将与领域研究人员密切合作，在真实系统上并行化具有挑战性的、不规则的、动态的应用程序，特别是在概率蛋白质结构确定和自适应非结构化网格方面，并了解它们对并行体系结构和软件的影响。将开发对这种复杂应用程序进行分区的通用技术，特别是针对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。将审查架构影响，特别是通信需求、伸缩和资源分配，并制定伸缩方法。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，以了解它们的通信架构和权衡的影响，并研究对编程和性能调试环境的见解。在教育方面，将开发一门新的并行建筑本科课程，并正在编写一本关于并行建筑的教科书，以阐明这一融合并将并行建筑发展为一门工程学科，而不是外来学科。

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.
