Member Function/Subroutine Documentation

subroutine, public mod_oasis_part::oasis_def_partition	(	integer(kind=ip_intwp_p), intent(out)	id_part,
		integer(kind=ip_intwp_p), dimension(:), intent(in)	kparal,
		integer(kind=ip_intwp_p), intent(out), optional	kinfo,
		integer(kind=ip_intwp_p), intent(in), optional	ig_size,
		character(len=*), intent(in), optional	name
	)

The OASIS user interface to define partitions.

Parameters

[out]	id_part	partition id
[in]	kparal	decomposition information
[out]	kinfo	return code
[in]	ig_size	total size of partition
[in]	name	name of partition

• Increment partition number and store user values

Definition at line 58 of file mod_oasis_part.F90.

subroutine, public mod_oasis_part::oasis_part_create	(	integer(ip_i4_p), intent(out)	id_part,
		character(len=*), intent(in)	TYPE,
		integer(ip_i4_p), intent(in)	gsize,
		integer(ip_i4_p), intent(in)	nx,
		integer(ip_i4_p), intent(in)	ny,
		character(len=*), intent(in)	gridname,
		integer(ip_i4_p), intent(in)	gscomm,
		integer(ip_i4_p), intent(in)	mpicom
	)

Create a new partition internally, needed for mapping.

Parameters

[out]	id_part	partition id
[in]	type	type of decomposition specified
[in]	gsize	global size of grid
[in]	nx	global nx size
[in]	ny	global ny size
[in]	gridname	grid name
[in]	gscomm	global seg map communicator
[in]	mpicom	local mpi comm

• Check if an existing gsmap can be reused
• Check that all tasks agree and if so, return with that partition id
• Instantiate a decomposition based on gsize and type
  • Create a new partition and set values
  • Initialize the partition gsmap and pgsmap

Definition at line 421 of file mod_oasis_part.F90.

subroutine, public mod_oasis_part::oasis_part_setup

(

)

Synchronize partitions across all tasks, called at oasis enddef.

• Generate reduced partname list
• Define all partitions on all tasks
• Convert kparal information to data for the gsmap
• Initialize the local gsmap and partition gsmap

Definition at line 140 of file mod_oasis_part.F90.

subroutine mod_oasis_part::oasis_part_write ( type(prism_part_type), intent(in)  s_prism_part, integer(ip_i4_p), intent(in)  npart  )

private

Print parition information.

Definition at line 380 of file mod_oasis_part.F90.

subroutine mod_oasis_part::oasis_part_zero ( type(prism_part_type), intent(inout)  s_prism_part )

private

Zero partition information.

Definition at line 352 of file mod_oasis_part.F90.
