CPR-like Preconditioners for Large-scale Linear Systems in Reservoir Simulations on GPUs

Bo Yang



This work shows that for large-scale highly heterogeneous reservoir simulation, CPR can be accelerated 6 times faster on average on Tesla C2050 GPU than on Intel Xeon X5570 CPU.  CPR has shorter running time than ILU0 on GPU. CPR has better convergence than ILU0 on GPU.
