Abstract:
The cuSolver, a new NVIDIA library, targets on sparse linear system and sparse eigenvalue system on a single GPU. In this talk, we will present Jacobi-Davidson method based on batched sparse QR in cuSolver library. The attendee can learn how to use cuSolver library in the scientific computation. Sparse eigenvalue system exists in many fields, including quantum chemistry, structure of photonic crystal and structural mechanics. Jacobi-Davidson is a Newton-like subspace method to solve exterior/interior eigenpairs. To improve performance of Jacobi-Davidson, pre-conditioners and subspace operations are key components. In this work, we use batched sparse QR factorization to speedup pre-conditioner on a subspace.  Back
