A method, apparatus, apparatus and medium for processing unstructured grid data. The method includes: acquiring grid data to be processed, wherein the grid data to be processed includes a plurality of elements; and dividing the grid data to be processed into blocks based on the data block size to obtain at least one data block, wherein the data block The size is determined according to the capacity of the processor cache of the computing device, and the size of the data block is smaller than the capacity of the processor cache, and wherein each data block in the at least one data block includes a plurality of intra-block elements, and the plurality of intra-block elements The element is at least a part of the multiple elements; the data block to be processed is determined in at least one data block; and the data block to be processed is loaded into the processor cache, wherein, before the processing of the data block to be processed is completed, the data block to be processed The multiple intra-block elements included in the data block are all retained in the processor cache.
Description
technical field [0001] The present disclosure relates to the field of computers, and in particular, to a method, apparatus, electronic device, non-transitory computer-readable storage medium and computer program product for processing unstructured grid data. Background technique [0002] Mesh is a common format for data discretization. According to the shape of the mesh, we can usually divide the mesh into structured mesh (Structured Mesh) and unstructured mesh (Unstructured Mesh). Structured mesh refers to the fact that all internal points in the mesh have the exact same shape. Common structured meshes include quadrilateral (two-dimensional) and hexahedral meshes (three-dimensional). This grid has excellent numerical properties and simple data access. But such grids can usually only be used to represent regular graphics. For irregularly structured graphics, it is difficult to accurately describe the surface structure of structured meshes. In contrast to structured grids...
