[MITgcm-support] [EXTERNAL] identifying connected regions

[Menemenlis, Dimitris (US 329B)]

Hi Dan, I don't know answer to first part of your question.

The gather routines you are looking for are located in MITgcm/eesupp/src/gather* and their opposite, scatter*

Subject: [EXTERNAL] [MITgcm-support] identifying connected regions

Hello -

I am curious if any part of model/src or a package implements an
algorithm to identify connected regions of a 2D (or 3D) array?

If not, i feel this might be best solved in serial, and am wondering
if there are utilities to gather processor tiles to a single 2D array
(and broadcast such an array to tiles) that should be used or are
ideal to use. I am aware that something like this must be done with
useSingleCpuIO but am not sure if this is the best template to follow.

Many thanks
Dan
