Dear HDF users,
A pre-release candidate version of HDF5 1.8.11 is available for testing
and can be downloaded at the following link:
http://www.hdfgroup.uiuc.edu/ftp/pub/outgoing/hdf5/hdf5-1.8.11/hdf5-1.8.11-pre2.tar.gz
For Windows users, there is an equivalent
http://www.hdfgroup.uiuc.edu/ftp/pub/outgoing/hdf5/hdf5-1.8.11/hdf5-1.8.11-pre2.zip
<http://www.hdfgroup.uiuc.edu/ftp/pub/outgoing/hdf5/hdf5-1.8.11/hdf5-1.8.11-pre2.tar.gz>
The tar ball contains fixes for a few CMake problems reported on FORUM
for the previous release candidate. Specifically, the requested
enhancement for building parallel HDF5 with CMake has been addressed.
Last time we failed to announce that HDF5 1.8.11 release will contain
two new features that may be of interest to anyone who works with the
compressed data in HDF5.
- Writing a compressed chunk bypassing HDF5 library internals for a
better speed.
We added a high-level function H5DOwrite_chunk documented here
http://www.hdfgroup.org/HDF5/doc_test/H51.8docs/Advanced/DirectChunkWrite/UsingDirectChunkWrite.pdf
-"Dynamically loaded filters in HDF5" will allow to load a compression
library at run time. With this feature the users will be able to use
the HDF5 library and tools distributed by The HDF Group with the
thrid-party HDF5 compression methods (and other filters).
The document that describes the feature and the BZI2 plugin example
is available from
http://www.hdfgroup.org/HDF5/doc_test/H51.8docs/Advanced/DynamicallyLoadedFilters/HDF5DynamicallyLoadedFilters.pdf
If you have some time to test this pre-release, we would greatly
appreciate it. Newly reported issues will be documented and will be
addressed in the next release.
Thank you!
-Albert Cheng
The HDF Group
