Communication behavior obtaining device for parallel multiprocessor system

Abstract

The invention provides a communication behavior obtaining device for a parallel multiprocessor system. The obtaining device comprises a plurality of original information collection modules and a communication information acquisition module, wherein the original information collection modules are attached in an intra-node communication module and / or an inter-node communication module, and used for, when the module to which the original information collection modules are attached are in communication, collecting the information related to the communication behavior and transmitting the information to the communication information acquisition module; and the communication information acquisition module is used for receiving the information from the plurality of original information collection modules and sending the collected information to an address specified by a user. The device grabs the communication information between a plurality of processors at the hardware level without influence on the running of specific application software; and simultaneously, the device has the advantages of application software independence, low expenditure, wide applicability and the like.

Description

technical field [0001] The invention belongs to the field of parallel multiprocessor systems, in particular to a communication system of the parallel multiprocessor system. Background technique [0002] The endless demand for computing speed in national defense, weather forecast, aerospace, ship design, life sciences, oil exploration and other fields drives the continuous development of high-performance computers. The design of high-performance computers mainly involves two aspects: one is the parallel multi-processor system The hardware architecture design, the second is the corresponding high-performance application software design. A large part of the design of the hardware architecture focuses on the construction of high-performance Internet, and the design of high-performance application software focuses on the development of efficient parallel algorithms. These two aspects are complementary. System structure designers need to customize the hardware communication netwo...

AI Technical Summary

Problems solved by technology

The disadvantages of the software acquisition method are: (1) it brings additional compilation link overhead and software runtime overhead; (2) adding test codes will affect the original communication behavior and cause unpredictable problems; (3) many applications are Mature commercial software, without open source code, it is difficult to operate it with software methods

[0004] However, there are relatively few tools based on hardware monitoring methods, and their functions only stay at the level of obtaining instruction information for accessing memory by a single processor. There is no tool based on hardware to obtain communication information between multiple processors.
