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_SELF

• n - 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.
