Embodiment 1

[0039] With the rapid development of supercomputer computing power, larger-scale, higher-precision, and longer-time calculations can be used to simulate more complex physical and chemical phenomena and engineering design issues. The resulting data is also growing explosively, and the calculation volume of a single simulation has reached TB / PB level of data. However, the I / O speed of supercomputers cannot keep up with the increase in computing speed, and the amount of ultra-large-scale data exceeds the storage capacity of supercomputers themselves. Data preprocessing and visualization in related technologies are basically post-processing modes. The massive data results output by the supercomputer after numerical simulation are stored in the disk, and the data is read from the disk when performing visualization processing. In this way, the blocking problem of data transmission and input / output port (Input / Output, referred to as I / O) bottleneck increases the difficulty of data pr...

Embodiment 3

[0108] The particle data processing method based on in-situ visualization in the embodiment of the present invention will be introduced below in combination with preferred implementation manners.

[0109] This embodiment is mainly aimed at the in-situ visualization technology of super-large-scale N-Body simulation, and the data mainly aimed at is unstructured particle data. Due to the irregular spatial distribution, it is difficult to compress the particles in the cosmological simulation.

[0110] In related technologies, there are many in-situ visualizations for volume data, which is uniform three-dimensional grid data. Existing researches have used probability density functions for in-situ data processing for in-situ visualization of volume data, that is, representing volume data through probability density functions. But they are targeting volume data, which is structured data, and there is currently no research on applying this method to particle data, which is unstructure...

Abstract

The invention discloses a particle data processing method, device and system based on in-situ visualization. The method is applied to a computing terminal and comprises the steps of obtaining to-be-processed original particle data; processing the original particle data based on a probability density function to obtain a target parameter; and transmitting the target parameter to a visual terminal,wherein the target parameter is used for being restored into target particle data on the visual terminal through a probability density function, and the difference value between the target particle data and the original particle data is smaller than a target threshold value, and the target parameter is used for performing visual processing on the visual terminal. According to the invention, the effect of effectively processing the particle data is achieved.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a particle data processing method, device and system based on in-situ visualization. Background technique [0002] At present, particle data is unstructured data, and particles in cosmological simulations are difficult to compress due to irregular spatial distribution. For the in-situ visualization processing of data, it is mainly for the in-situ visualization processing of volume data. Volume data has structure data, but currently it is not possible to directly apply the in-situ visualization processing method for volume data to particle data. [0003] In addition, in related technologies, in the preprocessing stage of particle data visualization, the vector quantization method can be used to simplify the particle attributes, and real-time decoding is performed on the Graphics Processing Unit (GPU) side during the visualization process. . Using the static codebook vector...
