面向数据流结构的指令映射优化方法

在高性能计算领域,数据流是一类重要的计算结构,也在很多实际场景表现出很好的性能和适用性。在数据流计算模式中,程序是以数据流图来表示的,数据流计算中一个关键的问题是如何将数据流图映射到多个执行单元上。通过分析现有数据流结构的指令映射方法及其不足,提出了基于数据流结构的新型指令映射优化方法。主要是根据多地址共享数据包的特性对指令映射方法进行优化,延迟多地址共享数据路由包的拆分,减少网络拥堵。

An instruction mapping optimization method based on dataflow architecture

In the field of high-performance computing, dataflow computation is an important computing architecture and shows good performance and applicability in many practical scenarios. In the dataflow computation mode, the program is represented by a dataflow diagram. A key problem of dataflow computation is how to map dataflow diagrams to multiple execution units. By analyzing the instruction mapping methods of current dataflow architecture and their shortcomings, we propose a new instruction mapping optimization method based on dataflow architecture, and achieve code implementation and verification. We optimize the instruction mapping method according to the characteristics of multi-address shared data packets, delay the splitting of multi address shared data packets, and reduce network congestion.
