Dave, I briefly read the papers and it suggests the SLOAVx algorithm is implemented by the ml collective module this module had some issues and was judged not good for production. it is disabled by default in the v1.10 series, and has been simply removed from the v2.x branch.
you can either use (at your own risk ...) v1.10 or master with mpirun --mca coll_ml_priority 100 ...
