Embodiment Construction

[0067] In order to make the purpose, technical solution and advantages of the present invention clearer, a parallel simulator and method of the present invention will be further described in detail below in conjunction with the accompanying 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.

[0068] Please refer to FIG. 1 , which is a frame diagram of the parallel simulator of the present invention. The parallel simulator 10 in the present invention includes a simulation kernel (simulation kernel, simk) module 11 (framework) and a simulation sub-module 12 . The emulation kernel module 11 is used to implement functions similar to the operating system. In a specific embodiment of the present invention, the emulation kernel module 11 is used to implement load deployment, memory management, and load deployment in the parallel simulator 10. Synchronize, c...

Abstract

The invention relates to the computer field, which discloses a parallel simulator and the related method. The parallel simulator and method integrate functions of synchronization, communication and scheduling, etc. in the parallel simulator, so as to form a framework; simultaneously, the invention provides a basic application programming interface API for user, the function of the parallel simulator can be realized when user calls the basic application programming interface API under the precondition that only the framework constraint is satisfied.

Description

technical field [0001] The invention relates to the field of computers, in particular to a parallel simulator and its method. Background technique [0002] Simulator is an important tool that researchers need in the process of studying computer architecture. Execution-driven system simulators have been widely used in many aspects because of their high simulation accuracy and the ability to develop and debug system software. At present, the main factor that limits the use of system simulators is the operating speed of the simulator. The interpreted reduction ratio of a functional-level simulator is generally about 1000 times, while a clock-level simulator is 1 to 2 times slower than a functional-level simulator. Magnitude. Since the current uniprocessor is gradually developing from single-core to multi-core, the scale of high-performance computers has reached tens of thousands or even hundreds of thousands of nodes, and the resulting increase in the scale of the target syste...
