HDF5 Parallel Test Suite

The HDF5 library is located on bitbucket. But the parallel test suite will not all pass since there is some unsupported functionality used by HDF5:

• atomicity
• POSIX and MPI-IO access of the same file
• reading empty data expecting 0s (default fill-value)

Those changes can be obtained from 

git clone https://github.com/mchaarawi/hdf5

Which is a clone of HDF5 develop branch with the above changes.

Build:

After configure and building MPICH (see directions here):

• git clone https://github.com/mchaarawi/hdf5
• cd hdf5
• ./autogen.sh
• mkdir build; cd build

• ../configure --enable-parallel --prefix=dir

• make -j8 install

Run:

Launch server(s)

Using all the directions from this page for client side execution:

1. create pool with dmg and export related env variables

2. export HDF5_PARAPREFIX=daos:

3. mpirun -np 6 --hostfile ~/cli_hosts ./testphdf5

4. mpirun -np 6 --hostfile ~/cli_hosts ./t_shapesame
   

Status:

Passing / Should Pass all tests
