Hello,
I am trying to use MPI_T interface to set *coll_tuned_bcast_algorithm* mca
parameter during run time, however I was not successful to do that.
I wonder if is it currently supported in Open MPI.
I had the same problem with setting *btl_self_eager_limit *parameter.
The code I am using atta

Hello,
I would like to know if Open MPI provides some kind of mechanism to select
collective algorithms such as MPI broadcast during run time depending on
some logic. For example, I would like to
use something like this:
if (some_condition) ompi_binomial_broadcast(...);
else ompi_pipeline_broa
