Module Procedures

private subroutine BundleRegrid(srcBUN, dstBUN, rc)

The subroutine BundleRegrid regrids a source bundle (srcBUN) into a destination bundle (dstBUN) using hinterp. A bundle is thought of as being comprised of n 2D slices (nslices) distributed among the n PEs (ns_per_pe). The limits among each ns_per_pe region are given by n1 and n2 which are functions of mype (the local PE):

                                                     slice_pe
           1 --- n1(pe=0)  -                     -->    0
           2 ---            |                    -->    0
              .             |_  ns_per_pe(pe=0)         .
              .             |                           0
              .             |                           0
             --- n2(pe=0)  -                            0
             --- n1(pe=1)                               1
              .                                         .
              .                                         .
              .                                         .
             --- n2(pe=1)                               1
             --- n1(pe=2)                               2
              .                                         .
              .                                         .
              .                                         .
          ns ---                                  slice_pe(ns)
              .                                         .
              .                                         .
              .                                         .
     nslices --- n2(pe=n)                        -->   npe

Each slice is gathered, regridded (hinterp), and scattered on a PE determined by a slice-to-PE map (slice_pe) to “load balance” the work of the serial hinterp function.
