HDF5 version 1.14.2 released on 2023-08-11
This branch contains modified source code of HDF5 r1.14.2. The code will be used to prototype changes for multi-threaded support before creating PRs to the HDF5 develop branch. This is for Lifeboat's internal use only but anyone is welcome to watch our progress.
For autotools builds, one must use the --enable-multithread option for configure
to enable the multithread support. For CMake builds, one must use the
HDF5_ENABLE_MULTITHREAD=ON option to enable the multithread support.
On Mac OS, this requires the presence of the Pthread library and the Atomic header
(stdatomic.h). On Linux, it requires the presence of the Pthread and Atomic libraries
and the Atomic header. Missing any of these requirements will cause configuration to
fail. Using the multithread feature requires disabling the high-level API, C++, Fortran,
Java interfaces, and thread safe.
The following commands are examples to enable the multithread support:
> configure --enable-build-mode=debug --enable-multithread --disable-hl
> cmake -DCMAKE_BUILD_TYPE=Debug -DHDF5_ENABLE_MULTITHREAD=ON -DHDF5_BUILD_HL_LIB=OFF ..
Currently, the only test program to check the correctness of multithread support is test/mt_id_test.c. During the build of the library and the test program, there are multiple warnings related to the atomic issues that we're investigating and fixing.
