George,
Thanks for the detailed answer. I will implement algorithms for MPI_Scan
and MPI_Exscan and send a PR.
Thanks,

Mikhail,
Some of these algorithms have been left out due to practical purposes, they
did not behave better than existing algorithms in any case. Some other
(such as Traff's butterfly or double tree) because the implementation
efforts shifted to other types of collective, or because there was a lac
Dear Devel List,
Current version of collective communication frameworks basic, base and
tuned does not include implementations of some well-known algorithms:
* MPI_Bcast: knomial, knomial with segmentation, binomial scatter +
recursive doubling allgather, binomial scatter + ring allgather
* MPI_G
