CRI: II-NEW: MYSTIC: Programmable Systems Research Testbed to Explore a Stack-WIde Adaptive System fabriC

该项目将为可重构通信和输入/输出子系统的实验建立一个试验台，以进行低水平的系统研究。这项研究的目标是通过根据应用程序的需求动态重新配置来消除网络、内存和存储性能瓶颈。随着计算应用程序的性质从以计算为中心转变为以数据为中心，数据通信构成了程序执行的很大一部分。在该试验台中，内存、存储及其连接的组织将动态变化，以适应工作负载，从而提高执行程序的整体性能。PI将构建一个名为Mytic的动态可配置集群，以研究从处理器到内存、存储和网络的整个计算堆栈的系统可重配性。它将允许在片上网络(NoC)、通用存储器和具有多维网络拓扑的网络互连级别进行低级别实验和重新配置。动态重新配置互连、内存和存储将加快在异类计算环境中运行的应用程序的速度。目标应用的示例包括用于负载平衡的动态多路径路由、部署用于持久存储的字节可寻址非易失性双列直插式存储器模块(NVDIMM)的通用存储器以及操作系统的片上网络(NOC)抽象。

This project will build a testbed for experimenting with reconfigurable communication and Input/Output subsystems to conduct low-level systems research. This goal of this research is to remove network, memory and storage performance bottlenecks by dynamically reconfiguring them to the needs of an application. As the nature of computing applications change from compute-centric to data-centric, communication of data comprises a large part of program execution. In this testbed, the organization of memory, storage and their connectivity will change dynamically to adapt to the workload to improve overall performance of the executing programs. The PIs will build a dynamically configurable cluster called MYSTIC to study system re-configurability across the entire computing stack, from the processor to memory, storage, and the network. It will allow low-level experimentation and reconfiguration at the level of networks-on-chip (NoC), universal memory, and the network interconnect with multidimensional network topologies. Dynamically reconfiguring interconnects, memory and storage will speed-up applications running on a heterogeneous computing environment. Examples of target applications include dynamic multipath routing for load-balancing, universal memory that deploys byte addressable Non-Volatile Dual In-line Memory Module (NVDIMM) for persistent storage and Network-on-Chip (NoC) abstractions for Operating Systems.
