Deflated Preconditioned Conjugate Gradient on the GPU
Speakers:
Kees Vuik, Rohit Gupta
- Delft University Of Technology
Abstract:
Explore how to use deflation as a second level preconditioning technique to speed up Block Incomplete Cholesky Preconditioned Conjugate Gradient Method. We use it to solve the Pressure correction equation involved in the solution of the Two-Phase Fluid Flow problem. Our implementation reaches speedup factors between 25-30, for more than 260,000 unknowns, when compared to the CPU.
