public subroutine tem_find_depProc(depProc, nDepProcs, tree, elemPath, PathFirst, PathLast)

Find the partitions holding data on a given path

Using a binary search over the processes first and last elements.

Is the element in question a local or remote element? To look up a certain element by its treeID in the distributed list of elements, it is sufficient to know the splitting positions of all chunks. That is, the first and last treeID of each partition. With a binary search over the splitting positions any requested element can then be identified to be either outside the computational domain at all, or inside of one or several known partitions.
