A simple Fortran example for the ParallelIO Library.

Function/Subroutine Documentation

program main

Main execution of example code.

This is an example program for the ParallelIO library.

This program creates a netCDF output file with the ParallelIO library, then writes and reads some data to and from the file.

This example does the following:

• initialization initializes the MPI library, initializes the ParallelIO library with PIO_init. Then allocate memory for a data array of sample data to write, and an array to read the data back into. Also allocate an array to hold decomposition information.
• creation of decomposition by calling PIO_initdecomp.
• creation of netCDF file with PIO_createfile.
• define netCDF metadata with PIO_def_dim and PIO_def_var. Then end define mode with PIO_enddef.
• write the sample data with PIO_write_darray. Then sync the file with PIO_syncfile.
• read the sample data with PIO_read_darray.
• close the netCDF file with PIO_closefile.
• clean up local memory, ParallelIO library resources with PIO_freedecomp and PIO_finalize, and MPI library resources.
