Daniel,
Many papers have been published about the performance modeling of different
collective communications algorithms (and fortunately these models are
implementation independent). I can pinpoint you to our research in
collective modeling which is the underlying infrastructure behind the

Daniel,
you can run
$ ompi_info --parseable --all | grep _algorithm: | grep enumerator
that will give you the list of supported algo for the collectives,
here is a sample output :
mca:coll:tuned:param:coll_tuned_allreduce_algorithm:enumerator:value:0:ignore
mca:coll:tuned:param:coll_tuned_allred
I am trying to survey the collective algorithms in Open MPI.
I looked at the src code but could not make out the guts of the communication
algorithms.
There are some open mpi papers but not detailed, where they talk about what
algorithms are using in certain collectives.
Has anybody done this sor

Can you explain what you mean / what you did?
E.g., did you build your algorithm code inside an OMPI tree and now
have an mca_coll_
