mpi_array.locale.LndarrayProxy

class mpi_array.locale.LndarrayProxy

Bases: object

Proxy for lndarray instances. Provides peer_rank views of the array for parallelism.

Methods

calculate_intra_partition(intra_locale_size, ...)	Splits extent into self.intra_locale_size number of tiles.
fill(value)	Fill the array with a scalar value (excludes ghost elements).
fill_h(value)	Fill the array with a scalar value (including ghost elements).
free()	Release locale array memory and assign None to self attributes.

Attributes

HI	The “high index” indices.
LO	The “low index” indices.
dtype	A numpy.dtype object describing the element type of this array.
halo	The number of ghost cells for intra locale partitioning of the extent.
intra_partition	A PartitionViewSlices containing slices for this rank (of peer_comm).
intra_partition_dims	A sequence of integers indicating the number of partitions along each axis which determines the per-rank views of the locale extent array.
lndarray	An lndarray instance containing array data in (potentially) shared memory.
locale_extent	A LocaleExtent describing the portion of the array assigned to this locale.
md	Meta-data object of type NdarrayMetaData.
rank_view_h	A tile view (including halo elements) of the array for this rank of peer_comm.
rank_view_n	A tile view of the array for this rank of peer_comm.
rank_view_partition_h	Rank tile view from the paritioning of entire self._lndarray (i.e.
rank_view_slice_h	Sequence of slice objects used to generate rank_view_h.
rank_view_slice_n	Sequence of slice objects used to generate rank_view_n.
shape	The shape of the locale array (including halo), i.e.
view_h	The entire LndarrayProxy view including halo (i.e.
view_n	View of entire array without halo.
