Multiprocessor shared storage method and system

Abstract

The invention discloses a multiprocessor shared storage method and system. The method comprises the steps: arranging at least one local interconnection network, wherein each local interconnection network is connected with at least two function modules; arranging local shared storage units connected with the local interconnection networks, and mapping the address space of the function modules on the local shared storage units; writing processed initial data into the local shared storage units through the local interconnection networks by the first function module of the at least two function modules; and obtaining data from the local shared storage units through the local interconnection networks by the second function module of the at least two function modules. According to the technical scheme disclosed by the invention, the defects that transport delay of the traditional multiprocessor global sharing storage system is large, managing expense is high and the like can be overcome.

Description

technical field [0001] The invention relates to the field of computer systems, in particular to a multiprocessor shared storage method and system. Background technique [0002] Traditional multiprocessor global shared memory systems such as figure 1 with figure 2 As shown, wherein, the functional modules include but not limited to processor modules such as general-purpose processor modules and configurable processor modules, and the global interconnection network includes but not limited to shared buses, crossbar switches, and various topological forms such as Mesh / Torus Connected to the network, the shared memory can be organized in a physically centralized or distributed manner. Here, the functional modules may include a local backup (i.e. cache) of the shared memory, figure 2 The shared memory in can also be integrated into the functional module as a tightly coupled memory TCM. [0003] In a traditional multiprocessor global shared memory system, the data exchange b...
