VecCreateSeqCUDA#
Creates a standard, sequential, array-style vector.
Synopsis#
#include <petscvec.h>
PetscErrorCode VecCreateSeqCUDA(MPI_Comm comm, PetscInt n, Vec *v)
Collective, Possibly Synchronous
Input Parameters#
comm - the communicator, must be
PETSC_COMM_SELFn - the vector length
Output Parameter#
v - the vector
Notes#
Use VecDuplicate() or VecDuplicateVecs() to form additional vectors of the same type as an
existing vector.
This function may initialize PetscDevice, which may incur a device synchronization.
