Abstract
This article presents the study and application of mixed precision techniques to accelerate a GPU-based implementation of the Strongly Implicit Procedure (SIP) to solve hepta-diagonal linear systems. In particular, two different options to incorporate mixed precision in the GPU implementation are discussed and one of them is implemented. The experimental evaluation of our proposal demonstrates that a runtime similar to a single precision implementation on GPU can be attained, but achieving a numerical accuracy comparable to double precision arithmetic.
