Embodiment Construction

[0098] In order to make the purpose, technical solution and advantages of the present invention clearer, a joint simulation system and its working method of the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0099] The joint simulation system and its working method of the present invention can accelerate the simulation of parallel application programs in heterogeneous systems, and achieve the purpose of quickly and detailedly obtaining feature information of various behaviors. Existing simulators simulate the details of the running behavior of each process of the application on all target nodes when simulating a massively parallel application. When the working sets used by each process are similar, it is meaningless to obtain the simulation details of all nodes. La...

Abstract

The invention discloses a united stimulation system and a working method thereof. The system comprises at least two physical computers, a system main control process module and process libraries, wherein, at least a physical computer comprises a host computer system module used for conducting host computer process, a management process module used for managing the host computer process on the physical computer of the management process module is arranged. At least a physical computer comprises a simulator or various simulators used for simulating target machines and obtaining characteristic information of the specific behavior of the target machine process, a proxy process module used for managing the stimulators on the physical computer of the proxy process module is arranged, and a target machine operation system module used for operating target machine process. The system main control process module is arranged on any of the physical computers and used for transmitting control commands to the proxy process module and the management process module. The process libraries are arranged on all the physical computers and used for unifying the communication operation of the simulation system.

Description

technical field [0001] The invention relates to the technical field of simulation system acceleration, in particular to a joint simulation system and its working method. Background technique [0002] A simulator can be understood as "a machine that simulates a certain hardware function by means of pure software". It is a fast and effective means for researching new high-performance computer architectures and an important tool for computer architecture researchers. When building a new system, the simulator can effectively test and verify the correctness of the new system and verify its performance, which can greatly reduce the cost and time of development. The use of simulators can enable hardware manufacturers to verify hardware before building a system, and software developers can also develop software before prototype production, making it possible for software and hardware to be released simultaneously. In addition, the simulator can collect machine operating information...
