PetscViewerHDF5SetSPOutput#

Data is written to disk in single precision even if PETSc is compiled with double precision PetscReal.

Synopsis#

#include "petscviewerhdf5.h" 
PetscErrorCode PetscViewerHDF5SetSPOutput(PetscViewer viewer, PetscBool flg)

Logically Collective

Input Parameters#

  • viewer - the PetscViewer; if it is a PETSCVIEWERHDF5 then this command is ignored

  • flg - if PETSC_TRUE the data will be written to disk with single precision

Options Database Key#

  • -viewer_hdf5_sp_output - turns on (true) or off (false) output in single precision

Note#

Setting this option does not make any difference if PETSc is compiled with single precision in the first place. It does not affect reading datasets (HDF5 handle this internally).
