MatSetBindingPropagates#
Sets whether the state of being bound to the CPU for a GPU matrix type propagates to child and some other associated objects
Synopsis#
#include "petscmat.h"
PetscErrorCode MatSetBindingPropagates(Mat A, PetscBool flg)
Input Parameters#
A - the matrix
flg - flag indicating whether the boundtocpu flag should be propagated
Notes#
If the value of flg is set to true, the following will occur
MatCreateSubMatrices()andMatCreateRedundantMatrix()- bind created matrices to CPU if the input matrix is bound to the CPU.MatCreateVecs()- bind created vectors to CPU if the input matrix is bound to the CPU.
The bindingpropagates flag itself is also propagated by the above routines.
Developer Notes#
If the fine-scale DMDA has the -dm_bind_below option set to true, then DMCreateInterpolationScale() calls MatSetBindingPropagates()
on the restriction/interpolation operator to set the bindingpropagates flag to true.
