Devels, We would like to change the definition of the OSC module to move the communicator one level up from the different module structures into the base OSC module. The reason for this, as well as a lengthy discussion on other possible solutions can be found in https://github.com/open-mpi/ompi/pull/4527.
We need to take a decision on this asap, to prepare the PR for the 3.1. Please comment asap. George.
