VecKokkosPlaceArray#

Allows one to replace the device array in a VecKokkos vector with a device array provided by the user. This is useful to avoid copying an array into a vector.

Synopsis#

Logically Collective; No Fortran Support

Input Parameters#

  • v - the VecKokkos vector

  • a - the device array

Notes#

You can return to the original array with a call to VecKokkosResetArray(). vec does not take ownership of array in any way.

The user manages the device array so petsc doesn’t care how it was allocated.

The user must free array themselves but be careful not to do so before the vector has either been destroyed, had its original array restored with VecKokkosResetArray() or permanently replaced with VecReplaceArray().
