HDF5 MPI-IO performance tests
This repository provides a collection of self-contained programs that test
the performance of the HDF5 MPI-IO driver. The purpose is to optimize the
use of parallel HDF5 in the [nano-dimer] molecular simulation software.
The tests require an MPI-2 library and HDF5 1.8 with MPI-IO support.
You may need to set `CPATH` and `LIBRARY_PATH` for compilation:
To compile all tests:
make -C test
To set hints for ROMIO, a commonly used MPI-IO implementation:
To run a test on 32 processes with 2 processes per host:
mpirun -np 32 -npernode 2 hdf5_mpio_collective_write_double
