This program contains sample codes for parallelly writing 2D/3D mesh field data and particle data into HDF5 files using the OpenPMD standard. The output file can be visualized using OpenPMD viewer.

The makefile is set to use gcc and gfortran with MPI. The HDF5-Parallel library (version 1.8.13) is also required for compiling the code.

To compile the programs, execute:

make

The program name is io.e

The command to execute the program is:

mpirun -np nproc ./io.e

where nproc is the number of processors to be used.
