◆ partition_init()

subroutine, public partition_oct_m::partition_init	(	type(partition_t), intent(out)	partition,
		integer(int64), intent(in)	np_global,
		type(mpi_grp_t), intent(in)	mpi_grp
	)

initialize the partition table

Parameters

[out]	partition	the partition table
[in]	np_global	total number of points to distribute
[in]	mpi_grp	the mpi groups

Definition at line 194 of file partition.F90.

◆ partition_end()

subroutine, public partition_oct_m::partition_end ( type(partition_t), intent(inout) partition )

Definition at line 231 of file partition.F90.

◆ partition_set()

subroutine, public partition_oct_m::partition_set	(	type(partition_t), intent(inout)	partition,
		integer, dimension(:), intent(in)	part
	)

Parameters

[in] part The local portion of the partition.

Definition at line 242 of file partition.F90.

◆ partition_dump()

subroutine, public partition_oct_m::partition_dump	(	type(partition_t), intent(in)	partition,
		character(len=*), intent(in)	dir,
		character(len=*), intent(in)	filename,
		integer, intent(out)	ierr
	)

write the partition data

Partition is written in parallel if MPI2 is available. Otherwise, is gathered in root and then written.

Definition at line 259 of file partition.F90.

◆ partition_load()

subroutine, public partition_oct_m::partition_load	(	type(partition_t), intent(inout)	partition,
		character(len=*), intent(in)	dir,
		character(len=*), intent(in)	filename,
		integer, intent(out)	ierr
	)

read the partition data

Partition is read in parallel if MPI2 is available. Otherwise, is read by the root and then scattered

Definition at line 304 of file partition.F90.

◆ partition_get_local_size()

subroutine, public partition_oct_m::partition_get_local_size	(	type(partition_t), intent(in)	partition,
		integer(int64), intent(out)	istart,
		integer, intent(out)	np_local
