Abstract :
Conjugate gradient (CG) solver implementations optimized for GPUs are developed and applied to a 3D finite element (FEM) problem. Results show that our GPUs implementations have a superior improvement in computational performance than cluster and other GPU implementations, due to algorithm and other architecture dependent optimizations.
