410 Designing Scientific Applications on GPUs
17.5 Summary
In this chapter, we have presented a new envelope-following method for
transient analysis of switching power converters. First, the computationally
expensive step, the solving of the Newton update equation, has been par-
allelized on CUDA-enabled GPU platforms with iterative GMRES solver to
boost performance of the analysis method. To further speed up the GMRES
solving for the Newton update equation, we have employed the matrix-free
Krylov basis generation technique. The proposed method also applies the
more robust Gear-2 integration to compute the sensitivity matrix. Experi-
mental results from ...
