Multi-FPGA interconnection structure and logic partitioning method oriented to high-performance computing

Abstract

The invention provides a multi-FPGA interconnection structure oriented to high-performance computing. The multi-FPGA interconnection structure comprises local communication interconnection networks and a global communication interconnection network. The local communication interconnection networks are of a full interconnection structure, and FPGA nodes can directly conduct communication with other FPGA nodes in the same local communication interconnection network. The global communication interconnection network is a high-speed communication interconnection channel and used for conducting communication among the local communication interconnection networks. The invention further provides a multi-FPGA logic partitioning method oriented to high-performance computing. The method includes the following steps of cluster structure parameter initialization and logical resource mapping. The multi-FPGA interconnection structure and logic partitioning method fully utilize the characteristics of locality and heterogeneity of large-scale computing, combine the topological structure and a logic partitioning algorithm, reduce system communication interconnection cost, achieve rapid and efficient mapping of larger-scale design to a multi-FPGA high-performance computing platform, and speed up the implementation of the design of a high-performance configurable computing system.

Description

technical field [0001] The invention relates to the field of high-performance computing, in particular to a multi-FPGA topology structure and a logic division method. Background technique [0002] High Performance Computing HPC (High Performance Computing) refers to the use of high-performance computers with super computing power to solve today's super-large, super-high and super-complex computing tasks. HPC has become the third most important scientific research method after "theory" and "test" in the development of science and technology, and has been used in space science, process engineering, earth science, bioinformatics, high energy physics and other important national science and technology, defense, industry and finance. fields are playing an increasingly important role. At present, the main schemes for realizing high-performance computing at home and abroad are two kinds of symmetric multiprocessor (SMP) and cluster machine (Cluster). The cluster system consists o...
