how to represent hdf5 variables as 64-bit ?

Daniel_Dombroski · January 31, 2011, 5:56am

Hi All,

I have a fortran code which I would like to compile with the 64 bit real and integer (-r8 and -i8) flags. However, I run into the problem of kind mismatches with the calls to hdf5 routines which do not like double precision. Is there a way to get hdf5 to handle the higher precision values?

Thanks,

-Dan

Daniel,

You will need to recompile HDF5 library using those flags, e.g.,

export FC="gfortran -i8"
./configure --enable-fortran ....
make

When we release the version that supports Fortran2003, recompilation would not be needed. Please let me know if you are interested to try our pre-released version.

Thank you!

Elena

Thanks Elena,

My code is on a DoD Cray XE6. I contacted their tech support to see if I could have them recompile, and they tried but ran into problems. I'm pasting their description of the issues below.

Daniel,
I cannot find any description of compiling HDF5 using "-i8 -r8" on the
HDF5 web site. In the distribution there is brief mention of now being able
to deal with "-i8 -r8" but the code does not look like it can deal with that.
There are generic functions such as

interface h5ltmake_dataset_f
module procedure h5ltmake_dataset_f_int1
module procedure h5ltmake_dataset_f_int2
module procedure h5ltmake_dataset_f_int3
module procedure h5ltmake_dataset_f_float1
module procedure h5ltmake_dataset_f_float2
module procedure h5ltmake_dataset_f_float3
module procedure h5ltmake_dataset_f_double1
module procedure h5ltmake_dataset_f_double2
module procedure h5ltmake_dataset_f_double3
end interface

but with -r8 h5ltmake_dataset_f_float1 and h5ltmake_dataset_f_double1 are
the same.

The release_doc/HISTORY-1_8.txt says that for the F90 API
Bug Fixes since HDF5-1.8.1
       - Put the DOUBLE PRECISION interfaces in a separate module and
          added a USE statement for the module. The interfaces are
          included/excluded depending on the state of FORTRAN_DEFAULT_REAL
          is DBLE_F which detects if the default REAL is DOUBLE PRECISION.
          This allows the library to be compiled with -r8 Fortran flag
          without the user needing to edit the source code.
          (MSB - 200/8/27)
The date above should be 2008/ rather than 200/ .

However, the h5ltmake_dataset_f module shown above is taken directly from the
code. It would appear that the bug fix by "MSB" neglected H5LT. In the
entire history file for version 1.8 "-i8" is mentioned only once and "-r8" is
mentioned only once. I'm inclined to believe that module h5lt is not
compatible with -r8.

Oh, yes, sorry...

Those are from the HL Fortran APIs. You will need to use --disable-hl configure flag to disable them.

If you are using fortran HL APIs, you are out of luck for now.

Hi Elena,

I'm not actually using any HL capabilities ... so what you're saying is that in that case, they can just use --disable-hl compile flag and everything should be ok?

That seems like really good news and a very easy fix
