Problems solved by technology

More precisely, GPUs are dedicated to solving problems that can be expressed as data-parallel operations: executing programs in parallel on many data elements, with extremely high computational density (ratio of mathematical operations to memory operations)
[0005] However, the existing cooperative operation of CPU and GPU is mainly through the combination of CPU and GPU processors with two different architectures, so as to only form a cooperative parallel mode on the hardware. This method is difficult to use CPU and GPU flexibly and effectively. Collaborative operations for data processing

Abstract

The invention provides a concurrent numerical simulation method and system based on GPU (Graphic Processing Unit) and CPU cooperative computing, which comprises a concurrent module selection unit and a concurrent granularity determination unit, wherein the concurrent module selection unit is used for selecting a function module suitable for carrying out concurrent operation from al function modules of a numerical simulation algorithm and promoting a CPU to execute residual function modules; and the concurrent granularity determination unit is used for determining an optimal concurrent granularity, adapting to a GPU, of each function module selected by the concurrent module selection module unit, and transplanting the function module with the determined optimal concurrent granularity to the GPU so that the GPU carries out data concurrent operation treatment by using the transplanted function module.

Description

technical field [0001] The invention relates to numerical simulation technology, more specifically, to a parallel numerical simulation method and a system using the method. Background technique [0002] Numerical simulation is a technology for simulating complex engineering and physical systems. It uses electronic computers as means to achieve the purpose of researching engineering problems, physical problems and even various problems in nature through numerical calculation and image display. The scope of application includes petroleum geophysical exploration and other fields. [0003] In recent years, as engineering and physical problems have become increasingly complex, the amount of data calculations for numerical simulations has also increased. For example, when numerical simulation is applied to the field of petroleum geophysical exploration, large-scale data calculation is usually required. It is estimated that the data processing calculation volume of typical seismi...
