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_Gather: binomial with segmentation * MPI_Reduce_scatter_block: Traff’s butterfly, recursive doubling with vector halving, recursive doubling, pairwise exch. with scattered destinations * MPI_Exscan: recursive doubling * MPI_Scan: recursive doubling * MPI_Alleduce: Rabensifner’s, knomial * MPI_Reduce: Rabensifner’s, knomial As far as I know, some of well-known collective algorithms have already been implemented in the Open MPI. But for the different reasons these algorithms are not used. I am implementing the above algorithms for my research. Does it make sense to implement these algorithms in the Open MPI?
