Hi Jeff, > Should these 2 components be in v1.3? for LibNBC: no. This was a test to implement blocking colls on top of non-blocking when the tuned implementation was lacking some ops (e.g., Allgather). Tuned now efficiently implements most collectives which makes the blocking version of LibNBC unnecessary. Non-blocking collectives are not supported by Open MPI (and were not implemented in this component).
I (as the author) would vote to delete it from the trunk :).
