Abstract

The invention provides a data processing system for a numerical program, and the system comprises: an input configuration module which is used for obtaining input configuration information; a management module which is at least used for registering the first storage grid based on the first configuration information; a data transmission and multi-dimensional interpolation management module which is at least used for completing data transmission between M I / O processes and N calculation processes of the numerical program; a data parallel input driving module which is used for establishing parallel subdivision of the first storage grid in the M I / O processes based on the second configuration information, operating the M I / O processes to read input data corresponding to a variable from a first file, and calling the data transmission and multi-dimensional interpolation management modulewhen the first storage grid is the same as a first calculation grid of the variable so as to enable the M I / O processes to send the input data to N calculation processes so as to input the input data to the variables in parallel.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a data processing system for numerical programs. Background technique [0002] Numerical programs for simulation calculations usually need to discretely represent the simulated object as a certain dimension (one-dimensional, two-dimensional, three-dimensional, four-dimensional, or even more dimensional) and resolution of the grid and the data on it, and then The corresponding mathematical model is numerically integrated and solved on the grid. Numerical programs usually have a large amount of calculation, and it is necessary to use MPI (Message Passing Interface) to parallelize the numerical program into a parallel program for multi-process cooperative computing, so as to accelerate the calculation by using the numerous processor cores of the high-performance computer. One of the numerical programs is The grid point set on the grid will be split into several su...
