- HDF5 supports collective MPI-IO for irregular selection with HDF5
dataset. Irregular selection is when users use H5Sselect_hyperslab
more than once for the same dataset.
Currently, not all MPI-IO packages support complicated MPI derived
datatype used in the implementation of irregular
selection INSIDE HDF5.
DEC 5.x is not supporting complicated derived datatype.
For AIX 5.1,
if your poe version number is 3.2.0.22 or higher,
please edit powerpc-ibm-aix5.x under hdf5/config,
Find the line with
<< hdf5_mpi_complex_derived_datatype_works>>
and comment out this line before the configure.
check poe version with the following command:
lpp -l all | grep ppe.poe
with IRIX 6.5,
if your C compiler version is 7.4 or higher,
please edit irix6.x under hdf5/config,
Find the line with
<< hdf5_mpi_complex_derived_datatype_works>>
and comment out this line before the configure.
check cc version with the following command:
cc -version

- HDF5 N-bit filter
HDF5 support N-bit filter from this version,
The N-Bit filter is used effectively for compressing data of N-Bit
datatype as well as compound and array datatype with N-Bit fields.
KY - 2005/04/15
- HDF5 scaleoffset filter
HDF5 supports scaleoffset filter for users to do data
compression through HDF5 library.
Scale-Offset compression performs a scale and/or offset operation
on each data value and truncates the resulting value to a minimum
number of bits and then stores the data.
Currently only integer datatype
is supported. Please check the HDF5 reference manual for this.
