ConstructLimitedRandomPermutation Subroutine

public subroutine ConstructLimitedRandomPermutation(this, actual_matrix_dimension, logical_matrix_dimension, process_grid_in)

Constructs a permutation that has a random order, but there is no permutation from beyond the actual matrix dimension.

Arguments

Type	Intent	Optional	Attributes		Name
type(Permutation_t),	intent(inout)			::	this	The permutation to construct.
integer,	intent(in)			::	actual_matrix_dimension	Actual size of the matrix.
integer,	intent(in)			::	logical_matrix_dimension	Padded size of the matrix.
type(ProcessGrid_t),	intent(inout),	optional		::	process_grid_in	A permutation should be shared amongst these processes. This is to synchronize random number across processes.
