VecCreateMPIHIP#

Creates a standard, parallel array-style vector for HIP devices.

Synopsis#

#include "petscvec.h"   
PetscErrorCode VecCreateMPIHIP(MPI_Comm comm, PetscInt n, PetscInt N, Vec *v)

Collective

Input Parameters#

  • comm - the MPI communicator to use . n - local vector length (or PETSC_DECIDE to have calculated if N is given)

  • N - global vector length (or PETSC_DETERMINE to have calculated if n is given)

Output Parameter#

. v - the vector

Notes#

Use VecDuplicate() or VecDuplicateVecs() to form additional vectors of the same type as an existing vector.
