Gravity inversion using wavelet-based compression on parallel hybrid CPU/GPU systems: application to southwest Ghana

We solve the 3-D gravity inverse problem using a massively parallel voxel (or finite element) implementation on a hybrid multi-CPU/multi-GPU (graphics processing units/GPUs) cluster. This allows us to obtain information on density distributions in heterogeneous media with an efficient computational...
