MatHIPSPARSESetUseCPUSolve

Sets use CPU MatSolve().

Synopsis

#include "petscmat.h" 
PetscErrorCode MatHIPSPARSESetUseCPUSolve(Mat A, PetscBool use_cpu)

Input Parameters

• A - Matrix of type MATSEQAIJHIPSPARSE

• use_cpu - set flag for using the built-in CPU MatSolve()

Notes

The hipSparse LU solver currently computes the factors with the built-in CPU method and moves the factors to the GPU for the solve. We have observed better performance keeping the data on the CPU and computing the solve there. This method to specifies if the solve is done on the CPU or GPU (GPU is the default).
