Multiprocessor system, device and method

Abstract

The invention discloses a multiprocessor system, a device and a method. The system comprises a plurality of processor nodes, wherein each processor node comprises at least two processors, an I / O bus and a shared resource between the processors; the processor nodes are connected with each other through an interconnecting network, wherein, each processor node also comprises a hardware lock device; the hardware lock device includes a plurality of hardware locks, a network interface, an I / O bus interface, a global address deployment module and a local address deployment module. The method of the invention has the following steps: when one processor in the multiprocessor system accesses the shared resource, the processor sends a test request to the hardware locks relative to the prospective shared resource through different addressing modes; the hardware locks relative to the prospective shared resource is tested, the prospective shared resource is obtained through different addressing modes. The locking can be realized simply and rapidly.

Description

technical field [0001] The invention relates to the field of realizing resource sharing in a multiprocessor system, in particular to a multiprocessor system with global unified addressing, a hardware lock device in the multiprocessor system and a hardware lock access method. Background technique [0002] When dealing with large-scale, calculation-intensive applications, computer systems with multiple processors are usually required to perform calculations. This system consists of many identical processor nodes, and each node contains four basic components of a computer: arithmetic unit, controller, memory, and input and output devices; all processor nodes are connected together through an interconnection network. [0003] Each processor node in a multiprocessor system can share resources with other processor nodes. [0004] One of the problems faced by multiprocessor systems is the orderly sharing of resources among processor nodes, which is specifically reflected in the mu...

Problems solved by technology

[0010] However, when accessing the memory through the hardware lock realized by the memory, the memory bus needs to be used, and a dozen cycles or even dozens of cycles are required to complete an access, which is too long to perform the hardware lock operation quickly, which affects the performance of the multiprocessor system. overall performance
