Description of Types
fd4_i4k_link
public type fd4_i4k_link
integer (kind=i4k), pointer :: l => NULL ()
end type fd4_i4k_link
fd4_neigh
public type fd4_neigh
type (fd4_mpitype), dimension (2) :: mpitype
type (fd4_r_k_link), dimension (2) :: minptr
type (fd4_i4k_link), dimension (2) :: minpti
logical :: changed = .false.
end type fd4_neigh
Components:
mpitype | MPI data type for send and receive |
minptr | pointer to type component with min address (real) |
minpti | pointer to type component with min address (integer) |
changed | flag to notify that neigh has been changed |
Description of Subroutines and Functions
fd4_neigh_allocate
private subroutine fd4_neigh_allocate (n, datatype_count)
type (fd4_neigh), intent(inout) :: n
integer (kind=i_k), intent(in) :: datatype_count
end subroutine fd4_neigh_allocate
Parameters:
n | pointer to fd4_neigh to allocate |
datatype_count | number of datatypes to allocate |
Allocate all data of the
fd4_neigh
fd4_neigh_deallocate
public subroutine fd4_neigh_deallocate (n)
type (fd4_neigh), intent(inout) :: n
end subroutine fd4_neigh_deallocate
Parameters:
n | fd4_neigh to deallocate |
Deallocate all data of the
fd4_neigh.
fd4_neigh_deallocate_ptr
public subroutine fd4_neigh_deallocate_ptr (n)
type (fd4_neigh), pointer :: n
end subroutine fd4_neigh_deallocate_ptr
Parameters:
n | pointer to fd4_neigh to deallocate |
Deallocate all data of the
fd4_neigh, pointer version.
Deallocates also the
fd4_neigh itself.
fd4_neigh_deallocate_type_ptr
public subroutine fd4_neigh_deallocate_type_ptr (n)
type (fd4_neigh), pointer :: n
end subroutine fd4_neigh_deallocate_type_ptr
Parameters:
n | pointer to fd4_neigh to deallocate |
Deallocate all data of the
fd4_neigh, pointer version.
Deallocates also the
fd4_neigh itself and the basic types.
