【 摘 要 】

2D lattice neutral models in ecology are studied using general-purpose computing on graphic processing units (GPGPU). Processing times of GPGPU and CPU simulations are compared for various system sizes and it is found out that the larger the system size, the faster the GPGPU version, and the efficiency of GPGPU is maximally 263 times higher. Ecological significance of the GPGPU simulations and the lattice neutral model is also reported.
