Multi-GPU parallel rendering system and method for space electromagnetic environment

Abstract

The invention discloses a multi-GPU parallel rendering system for a space electromagnetic environment, and the system comprises at least one physical machine, wherein each physical machine is provided with at least one GPU module used for carrying out rendering operation; a GPU agent module installed on each physical machine and used for identifying configuration and identifiers of the GPU modules on the physical machines, setting working states and parameters of the GPU modules, distributing rendering tasks to the GPU modules and collecting rendering results; a GPU virtual server used for managing the number, states and available resources of GPU agents, distributing rendering tasks and rendering parameters, collecting and fusing rendering results and supporting dynamic addition and deletion of GPU agent modules; an electromagnetic environment rendering module used for setting rendering parameters and generating an electromagnetic field of each radiation source and a coordinate transformation matrix of the electromagnetic field; and a communication bus used for mutually connecting the GPU agent module, the GPU virtual server and the electromagnetic environment rendering module. The space electromagnetic environment rendering work can be accelerated, a hardware structure does not need to be changed, and the expansibility is high.

Description

technical field [0001] The invention relates to the technical field of computer and information security, in particular to a multi-GPU parallel rendering system and method for a space electromagnetic environment. Background technique [0002] The electromagnetic environment is generated by the superposition of electromagnetic fields from multiple radiation sources. The electromagnetic field of each radiation source has relationships such as intersection, occlusion, and transparency. From a visualization point of view, it is expressed as the depth of color, light and shade, etc. The general drawing method of the electromagnetic environment is to generate the electromagnetic field of each radiation source, and draw the electromagnetic field through the volume rendering algorithm. The space electromagnetic environment generally has the characteristics of a large number of radiation sources and scattered geographical space. It has high requirements for the storage space of elec...
