PetscViewerHDF5Load#

Read a raw array from the PETSCVIEWERHDF5 dataset.

Synopsis#

#include "petsclayoutdf5.h"   
#include "petscis.h"   
PetscErrorCode PetscViewerHDF5Load(PetscViewer viewer, const char *name, PetscLayout map, hid_t datatype, void **newarr)

Collective; No Fortran Support

Input Parameters#

  • viewer - The PETSCVIEWERHDF5 viewer

  • name - The dataset name

  • datatype - The HDF5 datatype of the items in the dataset

Input/Output Parameter#

  • map - The layout which specifies array partitioning, on output the set up layout (with global size and blocksize according to dataset)

Output Parameter#

  • newarr - The partitioned array, a memory image of the given dataset

Notes#

This is intended mainly for internal use; users should use higher level routines such as ISLoad(), VecLoad(), DMLoad().

The array is partitioned according to the given PetscLayout which is converted to an HDF5 hyperslab.

This name is relative to the current group returned by PetscViewerHDF5OpenGroup().
