Function/Subroutine Documentation

pio_writedof_int()

subroutine __spio_decomp_f90__::pio_writedof_int	(	character(len=*), intent(in)	fname,
		integer, dimension(:), intent(in)	gdims,
		integer(i4), dimension(:), intent(in)	map,
		integer, intent(in)	comm,
		integer, intent(in), optional	ioid,
		integer, intent(out), optional	ierr
	)

Write/Save an I/O decomposition.

Parameters

[in]	fname	The name of the output file where the I/O decomposition will be saved/written out
[in]	gdims	The global dimensions of the I/O decomposition
[in]	map	The mapping between local data index and the global linearized index for each local data element e.g. If after partitioning the local array contains A(2,3) and A(3,3) of an array A[4x4], the map needs to contain [10, 11] corrsponding to the linearized indices of A(2,3) & A(3,3)
[in]	comm	The MPI communicator (that contains the MPI processes in the I/O system associated with the I/O decomposition)
[in]	ioid	(Optional) The I/O decomposition id
[out]	ierr	(Optional) : The error return code.

Set to PIO_NOERR on success, or an error code otherwise (See PIO_seterrorhandling for more information on how to customize/set error handling)

pio_writedof_offset()

subroutine __spio_decomp_f90__::pio_writedof_offset	(	character(len=*), intent(in)	fname,
		integer, dimension(:), intent(in)	gdims,
		integer(pio_offset_kind), dimension(:), intent(in)	map,
		integer, intent(in)	comm,
		integer, intent(in), optional	ioid,
		integer, intent(out), optional	ierr
	)

Write/Save an I/O decomposition.

Parameters
