RTM using effective boundary saving: A staggered grid GPU implementation
RTM via effective boundary saving is proposed for regular grid and staggered grid finite difference. CPML boundary condition is combined with staggered grid finite difference to minimize storage requirement. The GPU codes are provided for implementation and reproducible research. The Marmousi and Sigsbee models are used to demonstrate the validity of our method.
