Function/Subroutine Documentation
◆ init()
| subroutine pioexample::init | ( | class(pioexampleclass), intent(inout) | this | ) |
Initialize MPI, ParallelIO, and example data.
Initialize the MPI and ParallelIO libraries. Also allocate memory to write and read the sample data to the netCDF file.
◆ main()
| 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 Initialize an IOSystem. 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 Define a Decomposition.
- creation of netCDF file with Create a File.
- define netCDF metadata with Define a Dimension and Define a Variable. Then end define mode with Define Mode.
- write the sample data with Write from Distributed Arrays. Then sync the file with Sync File.
- read the sample data with Read to Distributed Arrays.
- close the netCDF file with Close a File.
- clean up local memory, ParallelIO library resources with Free a Decomposition and Free an IOSystem, and MPI library resources.
