kandi X-RAY | h5cpp Summary

h5cpp is a C++ library typically used in Modeling, 3D Printing applications. h5cpp has no bugs, it has no vulnerabilities and it has low support. However h5cpp has a Non-SPDX License. You can download it from GitHub.

Proud to announce to the HPC community that H5CPP is now MPI capable. The prerequisites are: c++17 capable MPI compiler, and linking against the Parallel HDF5 library. The template system provides the same easy to use functionality as in the serial version, and may be enabled by including parallel hdf5.h then passing h5::mpiio({mpi_com, mpi_info}) to h5::create | h5::open | h5::write | h5::read , as well as h5::independent and h5::collective data transfer properties. There are examples for independent, collective IO, as well as a short program to demonstrate throughput. The MPI extension supports all parallel HDF5 features, while the documentation is in progress please look at the tail end of H5Pall.hpp for details. Note: h5::append operator and attributes are not yet tested, and probably are non-functional.

H5Dwrite fails to write extendible dataset (HDF5)

Asked 2021-Apr-18 at 18:16

I want to write a function that will append a buffer to an extendible HDF5 dataset. The buffer will always have the same size (NXN) during the program execution. Following this brilliant answer Writing & Appending arrays of float to the only dataset in hdf5 file in C++ I have written the following code.

Answered 2021-Apr-18 at 14:29

I found the solution. After extending the dataset dimensions with H5Dset_extent(dset, dims); inside the else branch, one must execute file_space = H5Dget_space(dset);. The complete working solution is below. The function opens the file and if there is no dataset it writes the first buffer. If a dataset exists, it extends it and then writes the next buffer.

Change #include to #include "hdf5.h".

See What is the difference between #include and #include “filename”?.

The quotes around the #include will check in the current directory, while the angle brackets will check the include path.

How to write/read jagged arrays in a HDF5 file using the C++ API?

Asked 2020-Mar-03 at 18:10

I've multiple std::vector of different sizes containing floats. I would like to write/read them all as a jagged array in a HDF5 file (ideally one by one using hyperslabs since I can't hold all vectors in memory simultaneously). I believe I should use a regular array with each of its elements being of a variable length datatype, but all the examples I found were C examples. My code looks as follows:

Not sure how to do this with HDF5 C++ API, but you could try HDFql as it alleviates you from HDF5 low-level details. Using HDFql in C++, you could do the following to write/read an HDF5 jagged array:

QUESTION

Using pre-compiled HDF5 libraries with CMake under Windows

Asked 2019-Feb-12 at 20:58

I would like to use the pre-compiled HDF5 libraries in a CMake project which should be platform independent. The Linux version works very well, under Windows different problems occurred on different systems.

Question #1: Problem on Windows Server 2008, Visual Studio Ultimate 2012

On this machine, CMake 3.7.2 is used to generate the Visual Studio project. This works fine, the versions 1.8.18 and 1.10.1 of the HDF5 libraries are installed and found. The problem appears during compilation, where the header file inttypes.h is not found. This header file belongs somewhat to the C99 standard, which is not supported by some Visual Studio compiler versions. Are there any remedies to this problem?

Question #2: Problem on Windows 10, Visual Studio Enterprise 2017

Here, I installed HDF5 1.10.1 and CMake 3.10 and tried to build my simple example CMake script:

Answered 2019-Feb-12 at 20:58

This answer is the summary of the insights from the comments for later reference. Thanks to vre and the people in the HDF5 forum for their contributions.

The problem here was that the HDF5 library in the Windows installer was configured so that it assumes the presence of certain header files. One may adjust certain defines to get it right (see the discussion in the HDF5 forum), but the clean way is to compile the HDF5 library from scratch.

No solution here. Hence I switched to the module mode of CMake, which found the HDF5 library on every system.

There was another version of the hdf5.dll in the PATH variable. MATLAB and ParaView for example cause such behavior. A solution could be static linking. To achieve this, one has to get the PATH right at least at compile time. Maybe there is a CMake feature that gives an absolute path to the linker.

Still not sure what the best solution is to get safely through the DLL hell. I guess it is a rather general problem, but pointers are welcome anyway.

Maybe you want to try out HDFql and abstract yourself from HDF5 low-level details. In C++ using HDFql, you could read your variable-length char dataset mydata (contained in file myfile.h5) like this:
