Darshan HDF5 Testing Scripts

Python scripts used for generating Darshan logs with HDF5 data via h5py.

To Run

Create Darshan logs with only H5F data:

mpirun -x DARSHAN_LOGPATH=/path/to/logs/dir -x DARSHAN_DISABLE_SHARED_REDUCTION=1 -x LD_PRELOAD=/path/to/libdarshan.so:/path/to/libhdf5.so -np 3 python h5f_only.py

Create Darshan logs with DXT_POSIX, H5F and H5D (write) data:

python gen_hdf5_files.py write 1
mpirun -x DXT_ENABLE_IO_TRACE=1 -x DARSHAN_LOGPATH=/path/to/logs/dir -x DARSHAN_DISABLE_SHARED_REDUCTION=1 -x LD_PRELOAD=/path/to/libdarshan.so:/path/to/libhdf5.so -np 10 python diagonal_hdf5.py write 1

NOTE: Current Darshan instrumentation does not track the h5py read calls, so no H5D data is generated when executing the "read" mode. See this issue for details.
