mpi_array.distribution.GlobaleExtent.__init__

GlobaleExtent.__init__(slice=None, start=None, stop=None, halo=None, struct=None)

Construct.

Parameters:

• slice (sequence of slice) – Per axis start and stop indices defining the extent (not including ghost elements).
• start (sequence of int) – Per axis start indices defining the start of extent (not including ghost elements).
• stop (sequence of int) – Per axis stop indices defining the extent (not including ghost elements).
• halo ((len(slice), 2) shaped array of int) – A (len(self.start), 2) shaped array of int indicating the per-axis number of outer ghost elements. halo[:,0] is the number of elements on the low-index side and halo[:,1] is the number of elements on the high-index side.
