MatBindToCPU

marks a matrix to temporarily stay on the CPU and perform computations on the CPU

Synopsis

#include "petscmat.h"  
PetscErrorCode MatBindToCPU(Mat A, PetscBool flg)

Logically Collective

Input Parameters

• A - the matrix

• flg - bind to the CPU if value of PETSC_TRUE

Note

MATAIJKOKKOS has yet to implement CPU binding. If Kokkos is configured without GPU support, we deem a MATAIJKOKKOS matrix as bound to the CPU. Different from MATAIJVIENNACL with a CPU backend, MATAIJKOKKOS always use its own operation implementations (in constrast to CPU-bound MATAIJVIENNACL, which uses MATAIJ’s CPU operations).
