Embodiment Construction
[0044] The present invention will be described below in conjunction with the accompanying drawings and specific embodiments.
[0045] In one embodiment, the atomic simulation of the single crystal silicon system is realized by using the Tersoff many-body interaction model on a computer loaded with a graphics processing unit GPU. In this embodiment, the GPU adopted by the computer system has the following configuration: integrated 128 computing cores, including 1.6G bytes of global memory (Global Memory), 64K bytes of constant memory (Constant Memory), and shared memory ( Shared Memory) and texture memory (Texture Memory), through the CUDA (Compute Unified Device Architecture) compilation environment to control the computing behavior on the graphics processing unit GPU.
[0046] The Tersoff multi-body interaction model involved in this embodiment is the prior art. For the convenience of understanding and the needs of the description below, the Tersoff multi-body interaction mod...
